Description

本発明は複合材料シートおよびそれを備える複合体部品に関し、特に、航空機や車両等に搭載される各種機器を外部の衝撃から保護する複合材料シートに関する。   The present invention relates to a composite material sheet and a composite part including the composite material sheet, and more particularly to a composite material sheet that protects various devices mounted on an aircraft, a vehicle, and the like from external impacts.

しかしながら、更に耐衝撃性を向上させることが望まれている。例えば、Ａｌなどの金属から形成された被保護体の表面を保護するシートとして繊維強化プラスチック単体で形成されたシートを用いると、強い衝撃が加えられた際に、その衝撃を十分に吸収することができず、被保護体が変形する（陥没する）という問題があった。   However, it is desired to further improve the impact resistance. For example, when a sheet made of a fiber reinforced plastic is used as a sheet for protecting the surface of an object to be protected formed of a metal such as Al, it absorbs the impact sufficiently when a strong impact is applied. There was a problem that the protected object could be deformed (depressed).

本発明は、上記の問題を解決するためになされたものであり、その主な目的は、従来の繊維強化プラスチック単体のシートよりも耐衝撃性に優れた複合材料シートを提供することにある。   The present invention has been made in order to solve the above-mentioned problems, and its main object is to provide a composite material sheet that is more excellent in impact resistance than a conventional sheet of fiber reinforced plastic.

本発明の複合材料シートは、被保護体の表面に配置される複合材料シートであって、 前記被保護体側に配置される、ポリカーボネートから形成された非繊維強化プラスチック層と、前記非繊維強化プラスチック層の前記被保護体とは反対の側に配置される、アラミド繊維または炭素繊維と樹脂とを含む繊維強化プラスチック層とを有することを特徴とする。   The composite material sheet of the present invention is a composite material sheet disposed on the surface of a protected object, the non-fiber reinforced plastic layer formed of polycarbonate disposed on the protected body side, and the non-fiber reinforced plastic. It has the fiber reinforced plastic layer containing an aramid fiber or carbon fiber, and resin arrange | positioned on the opposite side to the said to-be-protected body of a layer.

本発明の複合体部品は、金属から形成された被保護体と、前記被保護体の表面に設けられた複合材料シートとを有し、前記複合材料シートが上記の複合材料シートであることを特徴とする。   The composite part of the present invention has a protected body formed of metal and a composite material sheet provided on the surface of the protected body, and the composite material sheet is the composite material sheet described above. Features.

本発明の複合材料シートは、外側に配置される繊維強化プラスチック層と内側に配置されるポリカーボネート層とを有する。繊維強化プラスチック層の高弾性または高剛性が外部からの強い衝撃に対する被保護体側への押し込み量を抑制するとともに、内側のポリカーボネート層が衝撃を効果的に吸収する。従って、本発明の複合材料シートは、従来の繊維強化プラスチック単体のシートよりも耐衝撃性に優れる。   The composite material sheet of the present invention has a fiber reinforced plastic layer disposed on the outside and a polycarbonate layer disposed on the inside. The high elasticity or high rigidity of the fiber reinforced plastic layer suppresses the amount of pushing into the protected body against a strong impact from the outside, and the inner polycarbonate layer effectively absorbs the impact. Therefore, the composite material sheet of the present invention is more excellent in impact resistance than a conventional sheet of fiber reinforced plastic alone.

以下、図面を参照して、本発明における実施の形態の複合材料シートおよびそれを備える複合体部品の構成と特性を説明する。   Hereinafter, with reference to the drawings, the configuration and characteristics of a composite material sheet according to an embodiment of the present invention and a composite part including the composite material sheet will be described.

［実施の形態１］
図１に本発明における実施の形態１の複合材料シート１０を備える複合体部品１００の模式的な断面図を示す。 [Embodiment 1]
FIG. 1 is a schematic cross-sectional view of a composite component 100 including a composite material sheet 10 according to Embodiment 1 of the present invention.

複合体部品１００は、被保護体３０と、被保護体３０の表面に配置された複合材料シート１０とを有している。なお、ここでは、簡単のために被保護体３０としてＡｌ板を示している。Ａｌは塑性変形しやすいので、複合材料シート１０に高い耐衝撃性が求められる。   The composite component 100 includes a protected body 30 and a composite material sheet 10 disposed on the surface of the protected body 30. Here, an Al plate is shown as the protected body 30 for simplicity. Since Al is easily plastically deformed, the composite material sheet 10 is required to have high impact resistance.

複合材料シート１０は、被保護体３０側に配置されたポリカーボネートから形成された非繊維強化プラスチック層（単に「ポリカーボネート層」ということがある）１４と、非繊維強化プラスチック層１４の外側（すなわち被保護体とは反対の側）に配置された繊維強化プラスチック層１２とを有している。繊維強化プラスチック層１２は、アラミド繊維または炭素繊維と樹脂とを含む。後述するように、繊維強化プラスチック層は単一の層から形成されてもよいし、複数の層からなる積層構造を有してもよい。   The composite material sheet 10 includes a non-fiber reinforced plastic layer 14 (sometimes simply referred to as a “polycarbonate layer”) 14 formed of polycarbonate disposed on the protected body 30 side, and an outer side of the non-fiber reinforced plastic layer 14 (that is, a covered material). And a fiber reinforced plastic layer 12 disposed on the side opposite to the protective body. The fiber reinforced plastic layer 12 includes aramid fibers or carbon fibers and a resin. As will be described later, the fiber-reinforced plastic layer may be formed from a single layer or may have a laminated structure including a plurality of layers.

複合材料シート１０の厚さは１ｍｍ以上１０ｍｍ以下の範囲にあることが好ましい。この範囲よりも小さいと、十分な耐衝撃性が得られず、大きいと重量増加という問題が発生することがある。また、繊維強化プラスチック層１２の厚さは、複合材料シート１０の厚さの５０％以上８０％以下の範囲で特に被保護体３０側への押し込み量を抑制する効果が顕著になる。また、ポリカーボネート層１４の厚さは、複合材料シート１０の厚さの２０％以上５０％以下の範囲で特に衝撃吸収効果が顕著になる。   The thickness of the composite material sheet 10 is preferably in the range of 1 mm or more and 10 mm or less. If it is smaller than this range, sufficient impact resistance cannot be obtained, and if it is larger, a problem of weight increase may occur. Further, the thickness of the fiber reinforced plastic layer 12 is in the range of 50% or more and 80% or less of the thickness of the composite material sheet 10, and the effect of suppressing the pushing amount to the protected body 30 side is particularly remarkable. Further, the impact absorption effect is particularly remarkable when the thickness of the polycarbonate layer 14 is in the range of 20% to 50% of the thickness of the composite material sheet 10.

繊維強化プラスチック層１２に用いられる樹脂としては、熱硬化性樹脂および熱可塑性樹脂のいずれを用いても良い。熱硬化性樹脂としては、例えば、不飽和ポリエステル樹脂、ビニルエステル樹脂、エポキシ樹脂およびフェノール樹脂を例示することができる。また、熱可塑性樹脂としては、ポリカーボネート、ポリエチレン、ポリプロピレン、ポリアミド、ポリアミドイミド、ポリスルホン、ポリアセタール、ポリフェニレンエーテル、ポリフェニレンスルフィド、ポリアリレート、ポリエーテルイミド、ポリエーテルスルホンおよびポリエーテルケトン、さらにこれらのブレンドポリマーを例示することができる。
好ましくは、エポキシ樹脂である。 As the resin used for the fiber reinforced plastic layer 12, either a thermosetting resin or a thermoplastic resin may be used. Examples of the thermosetting resin include unsaturated polyester resins, vinyl ester resins, epoxy resins, and phenol resins. The thermoplastic resin includes polycarbonate, polyethylene, polypropylene, polyamide, polyamideimide, polysulfone, polyacetal, polyphenylene ether, polyphenylene sulfide, polyarylate, polyetherimide, polyethersulfone and polyetherketone, and blended polymers thereof. It can be illustrated.
Preferably, it is an epoxy resin.

繊維強化プラスチック層１２中の繊維の体積分率は３０％以上７０％以下の範囲で特に被保護体３０側への押し込み量を抑制する効果が顕著になる。   The effect of suppressing the amount of pushing into the protected body 30 side is particularly remarkable when the volume fraction of the fibers in the fiber reinforced plastic layer 12 is in the range of 30% to 70%.

非繊維強化プラスチック層１４は、例えば射出成形法により製造することができる。また、繊維強化プラスチック層１２は、例えばプリプレグ製造法により製造することができる。これらを積層させてなる複合材料シート１０は、例えば非繊維強化プラスチック層１４と繊維強化プラスチック層１２とを接着することにより製造することができる。   The non-fiber reinforced plastic layer 14 can be manufactured by, for example, an injection molding method. The fiber reinforced plastic layer 12 can be manufactured by, for example, a prepreg manufacturing method. The composite material sheet 10 formed by laminating them can be manufactured by, for example, bonding the non-fiber reinforced plastic layer 14 and the fiber reinforced plastic layer 12 together.

以下、具体的に実施例を示して、本発明における複合材料シートの構造と耐衝撃性を説明する。   Hereinafter, the structure and impact resistance of the composite material sheet according to the present invention will be described with specific examples.

［実施の形態２］
図２に本発明における実施の形態２の複合材料シート１０Ａを備える複合体部品１００Ａの模式的な断面図を示す。 [Embodiment 2]
FIG. 2 shows a schematic cross-sectional view of a composite component 100A including the composite material sheet 10A according to Embodiment 2 of the present invention.

複合体シート１０Ａは、単一の層から形成された繊維強化プラスチック層１２Ａを有しており、繊維強化プラスチック層１２Ａはアラミド繊維強化プラスチック層のみを有している。   The composite sheet 10A has a fiber reinforced plastic layer 12A formed from a single layer, and the fiber reinforced plastic layer 12A has only an aramid fiber reinforced plastic layer.

ここでは、複合材料シート１０Ａの全厚さを２．０ｍｍとし、繊維強化プラスチック層１２Ａ（第１層；アラミド繊維強化プラスチック）およびポリカーボネート層１４（第２層；ポリカーボネート）の厚さを種々変えたテストピース（１００×１００ｍｍ）を作製した（実施例１−１、１−２、１−３）。被保護体３０として、厚さ３０ｍｍの純アルミ板を用いた。被保護体３０の上に複合材料シート１０Ａを配置し、直径１５ｍｍの領域に１００Ｊの衝撃を印加する落錘試験を行った。試験後に、被保護体３０の表面の陥没深さを測定した。   Here, the total thickness of the composite material sheet 10A was set to 2.0 mm, and the thicknesses of the fiber reinforced plastic layer 12A (first layer; aramid fiber reinforced plastic) and the polycarbonate layer 14 (second layer; polycarbonate) were variously changed. Test pieces (100 × 100 mm) were produced (Examples 1-1, 1-2, and 1-3). A pure aluminum plate having a thickness of 30 mm was used as the protected body 30. A falling weight test was performed in which the composite sheet 10A was placed on the protected body 30 and an impact of 100 J was applied to a region having a diameter of 15 mm. After the test, the depression depth of the surface of the protected body 30 was measured.

また、比較例１−１として、複合材料シート１０Ａに替えて、厚さ２．０ｍｍのアラミド繊維強化プラスチック層だけからなるテストピースを用意した。また、比較例１−４として、ポリカーボネート層１４のみからなるテストピースを用意した。これらを用いて上記実施例と同様に耐衝撃性を評価した。   In addition, as Comparative Example 1-1, a test piece including only an aramid fiber reinforced plastic layer having a thickness of 2.0 mm was prepared in place of the composite material sheet 10A. Moreover, the test piece which consists only of the polycarbonate layer 14 was prepared as Comparative Example 1-4. Using these, the impact resistance was evaluated in the same manner as in the above example.

また、比較例１−２、１−３として、図４に示す複合材料シート２０のように、被保護体３０側に配置される繊維強化プラスチック層１２（第２層）と、繊維強化プラスチック層１２の外側に配置されるポリカーボネート層１４（第１層）とを有する複合体部品２００の構造について耐衝撃性を上記と同様の方法で評価した。なお、比較例１−２と１−３は、繊維強化プラスチック層１２およびポリカーボネート層１４の厚さが異なっている。   Further, as Comparative Examples 1-2 and 1-3, like the composite material sheet 20 shown in FIG. 4, a fiber reinforced plastic layer 12 (second layer) disposed on the protected body 30 side and a fiber reinforced plastic layer. The impact resistance of the structure of the composite part 200 having the polycarbonate layer 14 (first layer) disposed on the outside of 12 was evaluated in the same manner as described above. In Comparative Examples 1-2 and 1-3, the thicknesses of the fiber reinforced plastic layer 12 and the polycarbonate layer 14 are different.

表１は本実施の形態における、実施例および比較例の耐衝撃性を比較した特性表である。表１の結果から明らかなように、図２に示した構成を有する実施例の複合材料シート１０Ａは、外側から第１層目のアラミド繊維強化プラスチック層１２Ａが被保護体３０側への押し込み量を抑制し、加えて第２層目のポリカーボネート層１４が衝撃を吸収する効果により、比較例１−１〜１−４に比べていずれも被保護体３０の陥没深さが小さく、従来よりも耐衝撃性に優れていることがわかった。   Table 1 is a characteristic table comparing the impact resistance of the examples and comparative examples in the present embodiment. As is clear from the results in Table 1, in the composite material sheet 10A of the example having the configuration shown in FIG. 2, the first aramid fiber reinforced plastic layer 12A is pushed from the outside into the protected body 30 side. In addition, due to the effect that the second polycarbonate layer 14 absorbs the impact, the depth of depression of the protected body 30 is smaller than those of Comparative Examples 1-1 to 1-4, and compared with the conventional case. It was found to be excellent in impact resistance.

さらに、外側から第１層目にポリカーボネート層１４を配置した比較例１−２、１−３では、ポリカーボネート層１４の大きな変形により、第２層目のアラミド繊維強化プラスチック層１２からポリカーボネート層１４が剥離し大きく膨らむという不良が発生したのに対し、実施例のテストピースではこのような不良は発生しなかった。   Furthermore, in Comparative Examples 1-2 and 1-3 in which the polycarbonate layer 14 is disposed as the first layer from the outside, the polycarbonate layer 14 is changed from the second aramid fiber reinforced plastic layer 12 due to a large deformation of the polycarbonate layer 14. While such a defect that peeling and swelling greatly occurred, such a defect did not occur in the test piece of the example.

なお、特許文献１に記載されている技術は、繊維強化プラスチック層の表面の凹凸を防止、意匠性を高めるために、繊維強化プラスチック層の表面に非繊維強化樹脂層（例えばポリカーボネート層）を設けるものであり、一方、特許文献２に記載されている技術は、平滑な表面を得るために、２種類の繊維強化プラスチック層を配設するものである。しかし、これらは本発明とは構成が異なるだけでなく、表１の結果から分かるように、表面に繊維強化プラスチック層を設けたポリカーボネート層との２層構造にすることにより、優れた被保護体に対する損傷抑制効果を発揮する。例えば、表面にポリカーボネート層を設けると、繊維強化プラスチック層だけを用いる場合よりも被保護体３０の陥没深さが大きくなり、耐衝撃性を改善する効果は低い。ポリカーボネート層は強い衝撃に対して大きく変形するので、その結果として、被保護体の陥没量も大きくなったと考えられる。   The technique described in Patent Document 1 provides a non-fiber reinforced resin layer (for example, a polycarbonate layer) on the surface of the fiber reinforced plastic layer in order to prevent irregularities on the surface of the fiber reinforced plastic layer and enhance the design. On the other hand, in the technique described in Patent Document 2, two types of fiber-reinforced plastic layers are disposed in order to obtain a smooth surface. However, these are not only different in configuration from the present invention, but as can be seen from the results in Table 1, an excellent protected object is obtained by forming a two-layer structure with a polycarbonate layer having a fiber-reinforced plastic layer on the surface. Demonstrate the effect of suppressing damage to For example, when a polycarbonate layer is provided on the surface, the depressed depth of the protected body 30 becomes larger than when only the fiber-reinforced plastic layer is used, and the effect of improving the impact resistance is low. The polycarbonate layer is greatly deformed in response to a strong impact, and as a result, it is considered that the amount of depression of the protected object has increased.

上述したように、本実施の形態では、比較例１−１〜１−４に比べていずれも被保護体の陥没深さが小さく、従来よりも耐衝撃性能に優れていることがわかった。   As described above, in the present embodiment, it was found that the depth of depression of the protected body was smaller than those of Comparative Examples 1-1 to 1-4, and the impact resistance performance was superior to that of the conventional example.

［実施の形態３］
実施の形態３においても実施の形態２と同様に図２に示した構成を有しており、複合体シート１０Ａとして、繊維強化プラスチック層１２Ａが炭素繊維強化プラスチック層のみを有している点において異なっている。 [Embodiment 3]
Similarly to the second embodiment, the third embodiment also has the configuration shown in FIG. 2, and as the composite sheet 10A, the fiber reinforced plastic layer 12A has only a carbon fiber reinforced plastic layer. Is different.

先と同様に、複合材料シート１０Ａの全厚さを２．０ｍｍとし、繊維強化プラスチック層１２Ａ（第１層；炭素繊維強化プラスチック）およびポリカーボネート層１４（第２層）の厚さを種々変えたテストピース（１００×１００ｍｍ）を作製した（実施例２−１、２−２、２−３）。被保護体３０として、厚さ３０ｍｍの純アルミ板を用いた。被保護体３０の上に複合材料シート１０Ａを配置し、直径１５ｍｍの領域に１００Ｊの衝撃を印加する落錘試験を行った。試験後に、被保護体３０の表面の陥没深さを測定した。   As before, the total thickness of the composite material sheet 10A was 2.0 mm, and the thicknesses of the fiber reinforced plastic layer 12A (first layer; carbon fiber reinforced plastic) and the polycarbonate layer 14 (second layer) were variously changed. Test pieces (100 × 100 mm) were produced (Examples 2-1, 2-2, 2-3). A pure aluminum plate having a thickness of 30 mm was used as the protected body 30. A falling weight test was performed in which the composite sheet 10A was placed on the protected body 30 and an impact of 100 J was applied to a region having a diameter of 15 mm. After the test, the depression depth of the surface of the protected body 30 was measured.

また、比較例２−１として、複合材料シート１０Ａに替えて、厚さ２．０ｍｍの炭素繊維強化プラスチック層だけからなるテストピースを用意した。   In addition, as Comparative Example 2-1, a test piece including only a carbon fiber reinforced plastic layer having a thickness of 2.0 mm was prepared instead of the composite material sheet 10A.

また、比較例２−２、２−３として、図４に示す複合材料シート２０のように、被保護体３０側に配置される繊維強化プラスチック層１２（第２層）と、繊維強化プラスチック層１２の外側に配置されるポリカーボネート層１４（第１層）とを有する複合体部品２００の構造について耐衝撃性を上記と同様の方法で評価した。なお、比較例２−２と２−３は、繊維強化プラスチック層１２およびポリカーボネート層１４の厚さが異なっている。   Further, as Comparative Examples 2-2 and 2-3, like the composite material sheet 20 shown in FIG. 4, a fiber reinforced plastic layer 12 (second layer) disposed on the protected body 30 side and a fiber reinforced plastic layer. The impact resistance of the structure of the composite part 200 having the polycarbonate layer 14 (first layer) disposed on the outside of 12 was evaluated in the same manner as described above. In Comparative Examples 2-2 and 2-3, the thicknesses of the fiber reinforced plastic layer 12 and the polycarbonate layer 14 are different.

表２は本実施の形態における、実施例および比較例の耐衝撃性を比較した特性表である。表２の結果から明らかなように、図２に示した構成を有する実施例の複合材料シート１０Ａは、外側から第１層目の炭素繊維強化プラスチック層１２Ａが被保護体３０側への押し込み量を抑制し、加えて第２層目のポリカーボネート層１４が衝撃を吸収する効果により、比較例２−１〜２−３に比べていずれも被保護体３０の陥没深さが小さく、従来よりも耐衝撃性に優れていることがわかった。   Table 2 is a characteristic table comparing the impact resistance of the examples and comparative examples in the present embodiment. As is clear from the results in Table 2, the composite material sheet 10A of the example having the configuration shown in FIG. 2 is the amount by which the first carbon fiber reinforced plastic layer 12A is pushed into the protected body 30 from the outside. In addition, due to the effect that the polycarbonate layer 14 of the second layer absorbs the impact, the depression depth of the protected body 30 is smaller than those of Comparative Examples 2-1 to 2-3, compared with the conventional case. It was found to be excellent in impact resistance.

さらに、外側から第１層目にポリカーボネート層１４を配置した比較例２−２、２−３では、ポリカーボネート層１４の大きな変形により、第２層目の炭素繊維強化プラスチック層１２からポリカーボネート層１４が剥離し大きく膨らむという不良が発生したのに対し、実施例のテストピースではこのような不良は発生しなかった。   Furthermore, in Comparative Examples 2-2 and 2-3 in which the polycarbonate layer 14 is disposed as the first layer from the outside, the polycarbonate layer 14 is changed from the second carbon fiber reinforced plastic layer 12 due to the large deformation of the polycarbonate layer 14. While such a defect that peeling and swelling greatly occurred, such a defect did not occur in the test piece of the example.

アラミド繊維強化プラスチック層に替えて炭素繊維強化プラスチック層を用いた本実施例でも、先の実施例と同様に、比較例２−１〜２−３に比べていずれも被保護体の陥没深さが小さく、従来よりも耐衝撃性能に優れていることがわかった。   In the present example using a carbon fiber reinforced plastic layer instead of the aramid fiber reinforced plastic layer, as in the previous example, the depth of depression of the object to be protected is compared to Comparative Examples 2-1 to 2-3. It was found that the impact resistance was superior to that of the conventional product.

［実施の形態４］
図３に本発明における実施の形態４の複合材料シート１０Ｂを備える複合体部品１００Ｂの模式的な断面図を示す。 [Embodiment 4]
FIG. 3 shows a schematic cross-sectional view of a composite component 100B including the composite material sheet 10B according to Embodiment 4 of the present invention.

複合体シート１０Ｂの繊維強化プラスチック層１２Ｂは積層構造を有している。繊維強化プラスチック層１２Ｂは、炭素繊維強化プラスチック層１２ａとアラミド繊維強化プラスチック層１２ｂとを含む。例えば、アラミド繊維強化プラスチック層１２ｂが２つの炭素繊維強化プラスチック層１２ａの間に挟まれた積層構造を有する。   The fiber reinforced plastic layer 12B of the composite sheet 10B has a laminated structure. The fiber reinforced plastic layer 12B includes a carbon fiber reinforced plastic layer 12a and an aramid fiber reinforced plastic layer 12b. For example, it has a laminated structure in which an aramid fiber reinforced plastic layer 12b is sandwiched between two carbon fiber reinforced plastic layers 12a.

ここでは、複合材料シート１０Ｂの全厚さを３．０ｍｍとし、繊維強化プラスチック層１２Ｂの全体の厚さを２．０ｍｍ、２つ炭素繊維強化プラスチック層１２ａの合計の厚さを１．０ｍｍ、中間層であるアラミド繊維強化プラスチック層１２ｂの厚さを１．０ｍｍ、ポリカーボネート層１４の厚さを１．０ｍｍとしたテストピース（１００×１００ｍｍ）を作製した（実施例３−１）。被保護体３０として、厚さ３０ｍｍの純アルミ板を用いた。被保護体３０の上に複合材料シート１０Ｂを配置し、直径１５ｍｍの領域に１００Ｊの衝撃を印加する落錘試験を行った。試験後に、被保護体３０の表面の陥没深さを測定した。   Here, the total thickness of the composite material sheet 10B is 3.0 mm, the total thickness of the fiber reinforced plastic layer 12B is 2.0 mm, and the total thickness of the two carbon fiber reinforced plastic layers 12a is 1.0 mm. A test piece (100 × 100 mm) in which the thickness of the aramid fiber reinforced plastic layer 12b as the intermediate layer was 1.0 mm and the thickness of the polycarbonate layer 14 was 1.0 mm was produced (Example 3-1). A pure aluminum plate having a thickness of 30 mm was used as the protected body 30. The composite material sheet 10B was disposed on the protected body 30, and a falling weight test was performed in which an impact of 100 J was applied to a region having a diameter of 15 mm. After the test, the depression depth of the surface of the protected body 30 was measured.

表３は本実施の形態における、実施例および比較例の耐衝撃性を比較した特性表である。なお、表３には、比較のために、図２に示した、中間層を有しない繊維強化プラスチック層１２Ａ（図２参照）としてアラミド繊維強化プラスチック層を用いたテストトピース（実施例１−４）、および炭素繊維強化プラスチック層を用いたテストピース（実施例２−４）についての評価結果を併せて示す。   Table 3 is a characteristic table comparing the impact resistance of the examples and comparative examples in the present embodiment. In Table 3, for comparison, a test piece (Example 1-) using an aramid fiber reinforced plastic layer as a fiber reinforced plastic layer 12A (see FIG. 2) without an intermediate layer shown in FIG. The evaluation result about 4) and the test piece (Example 2-4) using a carbon fiber reinforced plastic layer is shown collectively.

表３から明らかなように、実施例３−１の陥没深さ最も小さい。すなわち、高剛性の炭素繊維強化プラスチック層１２ａで高弾性のアラミド繊維強化プラスチック１２ｂを挟んだサンドイッチ構造とすることで、他の実施例よりも被保護体の陥没深さがより小さくなり、耐衝撃性能がさらに向上することがわかった。   As is clear from Table 3, the depression depth of Example 3-1 is the smallest. That is, by adopting a sandwich structure in which the highly elastic aramid fiber reinforced plastic 12b is sandwiched between the highly rigid carbon fiber reinforced plastic layer 12a, the depressed depth of the protected body is smaller than in other embodiments, and the impact resistance is increased. It was found that the performance was further improved.

なお、積層構造はここで例示したものに限られず、繊維強化プラスチック層１２Ｂとして炭素繊維強化プラスチック層１２ａとアラミド繊維強化プラスチック層１２ｂとが交互に積層された構造を有するものを用いても同様の効果が得られる。   Note that the laminated structure is not limited to the one exemplified here, and the same thing may be used when the fiber reinforced plastic layer 12B has a structure in which carbon fiber reinforced plastic layers 12a and aramid fiber reinforced plastic layers 12b are alternately laminated. An effect is obtained.
