Description

纖維複合材料及其製法    Fiber composite material and manufacturing method thereof   

本發明係關於一種纖維複合材料及其製法，尤指一種具有制振(vibration damping)特性之纖維複合材料及其製法。 The present invention relates to a fiber composite material and a manufacturing method thereof, and more particularly to a fiber composite material having vibration damping characteristics and a manufacturing method thereof.

由於高分子纖維複合材料相關產品配合人類在輕量化、高強度及高設計自由度等要求下，結合各種功能特性及用途於輕量化的各種結構物用品中已是現今必然的發展趨勢。而複材產品朝輕薄短小發展，結構設計以高強度為重點，而物性強度越高的材料卻常會伴隨著脆性增加，所以當材料受力後常會因此脆性增加而斷裂，為解決此一問題則必須改善材料的阻尼特性，以增加其吸收受力後的制振效果。 As polymer fiber composite materials related to human requirements for light weight, high strength, and high design freedom, combining various functional characteristics and uses in various structural articles with light weight has become an inevitable development trend today. However, composite materials are becoming thinner, lighter and shorter. The structural design is focused on high strength. Materials with higher physical strength are often accompanied by increased brittleness. Therefore, when materials are stressed, they often break due to increased brittleness. In order to solve this problem, The damping characteristics of the material must be improved to increase its damping effect after absorbing the force.

運輸用機械手臂在高速移動(2.8m/秒)、旋轉(210°/秒)時會產生位移、變形與震動，高分子纖維複合材料製成之機械手臂因運動而產生形變之振幅擺動至停止的時間若過長時，需待較長的時間至擺動靜止或振幅降低至可接受之程度，方得再進行下一動作，如此勢必使產能受到影響，所以必須縮短振動的衰減時間，其產能動作才不致於降低。 The transport robot arm will move, deform, and vibrate during high-speed movement (2.8m / sec) and rotation (210 ° / sec). The robot arm made of polymer fiber composite material will oscillate to stop due to the amplitude of deformation due to movement. If the time is too long, you need to wait a long time until the swing is stationary or the amplitude is reduced to an acceptable level before you can perform the next action. This will inevitably affect the production capacity, so the vibration attenuation time must be shortened. The action is not reduced.

已有文獻指出纖維複合材料具制振之效果，惟仍有制振縮減比例不足及希望能同時維持材料硬度特性之問題待解決。 Existing literature points out that fiber composite materials have the effect of damping vibration, but there are still problems to be solved in which the reduction ratio of damping vibration is insufficient and it is desired to maintain the hardness characteristics of the material at the same time.

The resin layer is surrounded to form a hollow pipe body, so that the ratio of the number of layers of the at least one composite resin layer to the fiber prepreg layer between the outer wall and the inner wall of the hollow pipe is 1: 4 to 1: 7 ; And shaping the hollow tube body.

通常，纖維預浸布層的製備方法包括手工積層、噴佈、積層、連續積層、樹脂轉注成型、纏繞成型、片狀模造(SMC)、塊狀模造(BMC)、預浸成型、壓力釜成型等。 Generally, the preparation method of the fiber prepreg layer includes manual lamination, spraying, lamination, continuous lamination, resin injection molding, winding molding, sheet molding (SMC), block molding (BMC), prepreg molding, and autoclave molding. Wait.

於一具體實施例中，所述纖維的實例包含碳纖維、玻璃纖維、芳香族聚醯胺(克維拉，Kevlar)纖維、硼纖維、耐綸纖維、特多龍纖維、棉纖維、羊毛纖維、鋼纖維、鋁纖維或陶瓷鬚絲纖維，且可選自所述纖維的至少一者。本揭露中，纖維預浸布層之纖維經第一樹脂含浸，而該複合樹脂層經多層奈米碳管及第二樹脂混成，其中，第一樹脂及第二樹脂為相同或不同，且可包括熱塑性樹脂或熱固性樹脂。熱塑性可舉例包括聚碳酸脂(Polycarbonate，PC)、尼龍(Nylon)、聚丙烯(Polypropylene，PP)、聚苯硫醚(Polyphenylene sulfide，PPS)或聚醚醚酮(polyetheretherketone，PEEK)；熱固性樹脂可舉例包括環氧樹脂。 In a specific embodiment, examples of the fiber include carbon fiber, glass fiber, aromatic Kevlar fiber, boron fiber, nylon fiber, Tedlon fiber, cotton fiber, wool fiber, Steel fiber, aluminum fiber, or ceramic whisker fiber, and may be selected from at least one of the fibers. In this disclosure, the fibers of the fiber prepreg layer are impregnated with a first resin, and the composite resin layer is mixed with a multilayered carbon nanotube and a second resin, wherein the first resin and the second resin are the same or different, and may be Including thermoplastic resins or thermosetting resins. Examples of thermoplastics include polycarbonate (PC), nylon (Nylon), polypropylene (PP), polyphenylene sulfide (PPS), or polyetheretherketone (PEEK); thermosetting resins may Examples include epoxy resins.

於一具體實施例中，所述纖維預浸布層的厚度可為50μm至200μm；所述複合樹脂層的厚度可為5μm至200μm，此處的厚度可依所製備之構件剛性強度需求作調整。 In a specific embodiment, the thickness of the fiber prepreg layer may be 50 μm to 200 μm; the thickness of the composite resin layer may be 5 μm to 200 μm, and the thickness here may be adjusted according to the rigidity and strength requirements of the prepared component. .

咸信，當外力使樹脂與奈米碳管管壁間產生相對位移(滑動)時，其位移差值與介面間剪力的積分等於所產生的能量損耗，就是可產生減振的原因。 It is believed that when the external force causes relative displacement (sliding) between the resin and the wall of the carbon nanotube tube, the integral of the displacement difference and the shear force between the interfaces is equal to the energy loss generated, which is the reason for the vibration reduction.

於一具體實施例中，奈米碳管係使用多層奈米碳管， 以其多層之管壁提供相較於單層奈米碳管更多微滑動現象，累積的阻尼特性可快速地被放大，更有效抑制振動。 In a specific embodiment, the carbon nanotube system uses multilayer carbon nanotubes. The multilayer walls provide more micro-slipping than single-layer carbon nanotubes, and the accumulated damping characteristics can be quickly amplified. , More effectively suppress vibration.

另一方面，奈米碳管經改質後，係具有反應性官能基，該反應性官能基可為胺基、羧基、羥基或醯氯基，但不以此為限。該改質的方法可參考J.Mater.Chem.,2011,21,7337-7342所揭露之方法。 On the other hand, after the carbon nanotube is modified, it has a reactive functional group. The reactive functional group may be an amine group, a carboxyl group, a hydroxyl group, or a chloro group, but it is not limited thereto. The modified method can refer to the method disclosed in J. Mater. Chem., 2011, 21, 7337-7342.

此外，於一具體實施例中，奈米碳管之比表面積為100至300m2/g，使用此比表面積範圍的奈米碳管可使奈米碳管較佳地與第二樹脂混成，且該至少一複合樹脂層中之該奈米碳管之含量係0.5至8wt%。相對地，該至少一複合樹脂層中之該第二樹脂之含量係92至99.5wt%。 In addition, in a specific embodiment, the specific surface area of the nano carbon tube is 100 to 300 m 2 / g. Using the nano carbon tube in this specific surface area range allows the nano carbon tube to be better mixed with the second resin, and The content of the nano carbon tube in the at least one composite resin layer is 0.5 to 8 wt%. In contrast, the content of the second resin in the at least one composite resin layer is 92 to 99.5 wt%.

根據本揭露之方法，纖維複合材料係經加熱而塑形，在加熱過程中，奈米碳管的反應性官能基與第一樹脂及第二樹脂鍵結而硬化定型。 According to the disclosed method, the fiber composite material is shaped by heating. During the heating process, the reactive functional group of the nano carbon tube is bonded with the first resin and the second resin to be hardened and shaped.

一般而言，形成纖維複合材料之製法係使用傳統疊合方式，亦即，將所欲達到各層層數比例的不同材料層疊合後，經過捲曲再塑形。但此種製法一次僅能製造一個纖維複合材料，於工業上大量製造時係不經濟的。 Generally speaking, the manufacturing method of forming a fiber composite material uses a traditional lamination method, that is, after laminating different materials to achieve the proportion of each layer and layer, and then curling and shaping. However, this manufacturing method can only manufacture one fiber composite material at a time, which is uneconomical when it is mass-produced in industry.

因此，在另一具體實施例中，本揭露的纖維複合材料之製法係於纖維預浸布層上鋪墊至少一複合樹脂層，且根據需要，係於該纖維預浸布層上鋪墊複數該複合樹脂層，並令複數該複合樹脂層彼此間隔，並使得在形成中空管體後，該中空管體外壁至內壁之間的該至少一複合樹脂層與該纖維預浸布層的層數比例為1：4至1：7。具體而言，鋪墊 該複數該複合樹脂層時，該複合樹脂層係以沿著該纖維預浸布層捲曲方向間隔地鋪墊。因此，透過本揭露的一種纖維複合材料之製法，機器可更經濟地一次大量生產多個纖維複合材料。 Therefore, in another specific embodiment, the method for manufacturing the fiber composite material disclosed in the present invention is to pave at least one composite resin layer on the fiber prepreg layer, and pave a plurality of the composite on the fiber prepreg layer as required. A resin layer, and a plurality of the composite resin layers are spaced apart from each other, so that after the hollow pipe body is formed, the at least one composite resin layer and the fiber prepreg layer between the outer wall and the inner wall of the hollow pipe The number ratio is from 1: 4 to 1: 7. Specifically, when the plurality of composite resin layers are padded, the composite resin layer is padded at intervals along the curling direction of the fiber prepreg layer. Therefore, through a method for manufacturing a fiber composite material disclosed herein, the machine can more economically produce a large number of fiber composite materials at a time.

此外，根據本揭露之製法，所形成之該中空管體之形狀包含圓形、橢圓形、方形、矩形，但不限於此。 In addition, according to the manufacturing method of the present disclosure, the shape of the hollow pipe body formed includes a circle, an oval, a square, and a rectangle, but is not limited thereto.

本揭露透過實施例之示例來說明細節。不過，本揭露之詮釋不應當被限制於以下實施例之闡述。 This disclosure illustrates details through examples of embodiments. However, the interpretation of this disclosure should not be limited to the description of the following embodiments.

比較例一 Comparative example one

比較例一(編號：0)的製法與條件如第一實施例所敘述，於纖維預浸布層上不鋪墊複合樹脂層，達到捲曲後纖維預浸布層之層數為20的纖維複合材料。 The manufacturing method and conditions of Comparative Example 1 (No. 0) are as described in the first embodiment. The composite resin layer is not laid on the fiber prepreg layer, and the fiber composite material having a number of 20 layers of the fiber prepreg layer after crimping is reached. .

振動衰減時間(秒，S)之測量係使用雷射位移計(Polytec OFV 350 Sensor hand)，測量自振動開始(樣品之一端固定，另一端施加2Kg載重後釋放)至靜止之時間，並將結果記錄於表1。 The vibration decay time (second, S) is measured using a laser displacement meter (Polytec OFV 350 Sensor hand). It measures the time from the beginning of the vibration (one end of the sample is fixed and the other end is released after applying a 2Kg load) to the standstill, and the result is Recorded in Table 1.

根據表1，與未添加複合樹脂層之比較例相比，添加複合樹脂層之2L至6L實施例，可產生53.5%至89.2%的全振幅縮減效果。此外，表1之自然頻率係指一結構體本身存在之動態特性，其與系統剛性平方根成正比，與質量塊平方根成反比。因此，由表1可知，雖複合樹脂層之層數越多，全振幅縮減效果越高，惟複合樹脂層較纖維預浸布層軟，因此複合樹脂層不能無限增加，複合樹脂層與纖維預浸布層的層數比例最佳範圍在為1：4至1：7之間， 在此範圍內，纖維複合材料之制振效率與剛性同步提高，但當編號6L之複合樹脂層與纖維預浸布層的層數比例為1：3.3時，其制振效率雖可持續提高，但纖維複合材料剛性則會降低，不符合有需要求結構剛性之相關產品應用需求。 According to Table 1, compared with the comparative example without the composite resin layer, the 2L to 6L embodiment with the composite resin layer can produce a full amplitude reduction effect of 53.5% to 89.2%. In addition, the natural frequency of Table 1 refers to the dynamic characteristics of a structure itself, which is directly proportional to the square root of the system rigidity and inversely proportional to the square root of the mass. Therefore, it can be known from Table 1 that although the more layers of the composite resin layer, the higher the full amplitude reduction effect, but the composite resin layer is softer than the fiber prepreg layer, so the composite resin layer cannot be infinitely increased. The optimal range of the number of layers of the impregnated layer is between 1: 4 and 1: 7. Within this range, the vibration-damping efficiency and rigidity of the fiber composite material increase simultaneously. When the ratio of the number of layers of the cloth impregnation layer is 1: 3.3, although the vibration damping efficiency can be continuously improved, the rigidity of the fiber composite material will be reduced, which does not meet the application requirements of related products that require structural rigidity.
