Description
本発明はナイロン６及び下記（ｉ）〜（ii）を満足する炭素繊維を含有する熱可塑性樹脂組成物からなる、曲げ弾性率が５０００ＭＰａ以上、シャルピー衝撃試験によるノッチなし衝撃強度が９０ｋＪ／ｍ ２ 以上、比重が１．４以下である熱可塑性樹脂成形品に関するものである。
（ｉ）単繊維の表面に単繊維の長手方向に延びる皺が実質的に無く、
（ii）ストランド弾性率が２３０〜３７０ＧＰａである。
The present invention comprises a thermoplastic resin composition containing nylon 6 and carbon fibers satisfying the following (i) to (ii), a flexural modulus of 5000 MPa or more, and an unnotched impact strength by a Charpy impact test of 90 kJ / m 2. As described above, the present invention relates to a thermoplastic resin molded product having a specific gravity of 1.4 or less.
(I) The surface of the single fiber is substantially free from wrinkles extending in the longitudinal direction of the single fiber,
(Ii) The strand elastic modulus is 230 to 370 GPa.
このような物性を有する熱可塑性樹脂成形品は、ナイロン６を含有する熱可塑性樹脂（Ａ）と炭素繊維（Ｂ）を含有する熱可塑性樹脂組成物からなり、炭素繊維（Ｂ）が、下記（ｉ）〜（ii）を満足する熱可塑性樹脂組成物を成形することによって製造することができる。
（ｉ）単繊維の表面に単繊維の長手方向に延びる皺が実質的に無く、
（iii）ストランド弾性率が２３０〜３７０ＧＰａである。
The thermoplastic resin molded article having such physical properties comprises a thermoplastic resin (A) containing nylon 6 and a thermoplastic resin composition containing carbon fiber (B), and carbon fiber (B) has the following ( It can be produced by molding a thermoplastic resin composition satisfying i) to (ii).
(I) The surface of the single fiber is substantially free from wrinkles extending in the longitudinal direction of the single fiber,
(Iii) Strand elastic modulus is 230-370 GPa.
炭素繊維（Ｂ）は、下記（ｉ）〜（ii）を満足するものである。
（ｉ）単繊維の表面に単繊維の長手方向に延びる皺が実質的に無く、
（ii）ストランド弾性率が２３０〜３７０ＧＰａである。
The carbon fiber (B) satisfies the following (i) to (ii).
(I) The surface of the single fiber is substantially free from wrinkles extending in the longitudinal direction of the single fiber,
(Ii) The strand elastic modulus is 230 to 370 GPa.
炭素繊維（Ｂ）が上記（ｉ）〜（ii）を満足する場合に、得られる炭素繊維強化熱可塑性樹脂の衝撃強度が十分となる。
ここで、単繊維表面の皺は、電子顕微鏡で単繊維表面を観察し、繊維方向に溝があるか無いかを判定したものであり、単繊維の繊維断面の長径と短径との比は、電子顕微鏡度で単繊維の断面を観察して評価したものである。
When the carbon fiber (B) satisfies the above ( i) to (ii), the impact strength of the obtained carbon fiber reinforced thermoplastic resin is sufficient.
Here, the wrinkles on the surface of the single fiber are obtained by observing the surface of the single fiber with an electron microscope and determining whether or not there is a groove in the fiber direction. The cross section of the single fiber was observed and evaluated with an electron microscope.
