Abstract
Description
本発明に係る炭素繊維強化プラスチック成形品においては、成形品は、連続炭素繊維束が所定の一方向に配された一方向連続炭素繊維強化シートを含む少なくとも2層以上の積層体からなるが、このうちとくに、成形品の意匠面を形成する最表層の一方向連続炭素繊維強化シートの意匠面における炭素繊維について観察したとき、炭素繊維の角度が上記所定の一方向に対し3°以上傾いている炭素繊維の割合が0.5%以上ある箇所の、意匠面の全体に対する面積割合が20%以下であるものとされている。そして、前述したように、好ましくは、この最表層の一方向連続炭素繊維強化シートの炭素繊維目付が30g/m2以上100g/m2以下のものが用いられる。また、好ましくは前述したように、最表層の一方向連続炭素繊維強化シートの樹脂含有率が15質量%以上50質量%とされ、最表層の一方向連続炭素繊維強化シートにおける炭素繊維束1本の繊度が300tex以下とされる。さらに、好ましくは、前述したように、プリプレグの製造工程において炭素繊維束に0.5〜6N/texの張力を付与して引き揃えることによって炭素繊維束に樹脂を含浸させる前に炭素繊維束を予め目的幅の80〜98%まで拡幅する工程を経て製造された一方向連続炭素繊維強化シートが、上記成形品の意匠面を形成する最表層に用いられる。また、この最表層の一方向連続炭素繊維強化シートに用いられる炭素繊維として、引張弾性率が270GPa以上の炭素繊維を用いることが好ましい。また、成形品の意匠面を形成する最表層上にさらに樹脂シートが設けられる場合には、目付15g/m2以下の樹脂シートとされることが好ましい。
測定装置:KEYENCE VHX-500

画像視野範囲:3.04×2.28mm
倍率:100倍
解像度:1600×1200画素
測定点数:25point以上(ランダム)
撮影方法:繊維が主に0°(水平方向)を向くように撮影
OS:Windows(登録商標) XP

処理前画像(0)の読込→ノイズ除去→輪郭強調→2値化→膨張・収縮→細線化
→150画素(0.285mm)以上の長さの繊維を抽出(抽出画像(1))(実際には色づけされた繊維として抽出される。)
処理前画像(0)と抽出画像(1)の例を図2に示す。
上記抽出画像(1)で抽出された各繊維について、繊維の角度を割り出し、水平方向(0°方向)に対して±3°以上傾いた繊維10を抽出する(この抽出画像(2)においては、実際には色づけにより強調されて±3°以上傾いた繊維10が抽出される)。
±3°以上傾いた繊維の割合(%)=
[抽出画像(2)で抽出された繊維の面積(画素数)/抽出画像(1)で抽出された繊維の面積(画素数)]×100
実施例1
アクリロニトリル99.5モル%、イタコン酸0.5モル%からなる固有粘度[η]が1.80のアクリロニトリル系重合体を20質量%含むジメチルスルホキシド溶液を紡糸原液として、孔径が0.15mmφの6000ホールの口金を用いて一旦空気中に吐出し、10℃に温調されたジメチルスルホキシド35%水溶液から成る凝固浴に導入して凝固糸を得た。該凝固糸を水洗・延伸後、アミノ変性シリコーン分散物を主成分とした界面活性剤を付与した後、乾燥緻密化を行い、スチーム延伸装置を用いて延伸を行ない、円形断面で表面平滑な前駆体繊維を巻き取った。
この樹脂組成物を担持シートに塗布し、プリプレグ用樹脂シートを得た。
上記実施例1に対し、炭素繊維の引張弾性率や、炭素繊維束の繊度、プリプレグにおける炭素繊維目付や樹脂含有率、製造時の張力、拡幅率、意匠面に樹脂シート(目付15g/m2以下のPET不織布)を設けた場合などの他の条件の少なくとも一つを変更した場合(実施例2〜8、比較例1〜8)の試験結果を表2、表3に示す。
