上記比重、曲げ特性、シャルピー衝撃強さ、難燃性は後述する実施例の記載に従って測定される。
本実施形態の樹脂組成物は、熱可塑性樹脂と他の成分を含む樹脂組成物の常法の製法によって製造できる。例えば、本実施形態の樹脂組成物は、結晶性熱可塑性樹脂100質量部と、再生炭素繊維5~40質量部と、難燃剤5~60質量部とを押出機に投入し、溶融混練することを含む方法によって製造される。再生炭素繊維は、炭素繊維の表面に表面処理剤や収束剤が付着していない場合があるが、本実施形態では樹脂と炭素繊維の複合物の焼成物であり、かつ、樹脂由来の残渣を10質量%以上の割合で含む再生炭素繊維を用いることにより、樹脂由来の残渣が表面処理剤や集束剤等の役割を果たし、官能基含有化合物が再生炭素繊維の表面処理剤等の役割を果たし、押出機に投入しての溶融混練が可能になる。そのため、本実施形態の樹脂組成物から形成されたペレットとすることができる。
押出機には、各成分をあらかじめ混合して一度に供給してもよいし、各成分を予め混合することなく、ないしはその一部のみを予め混合し、フィーダーを用いて押出機に供給してもよい。押出機は、一軸押出機であっても、二軸押出機であってもよい。また、一部の成分を樹脂成分と溶融混練してマスターバッチを調製し、次いでこれに残りの成分を配合して溶融混練してもよい。
なお、再生炭素繊維は、押出機のシリンダー途中のサイドフィーダーから供給することも好ましい。
溶融混練に際しての加熱温度は、通常、220~350℃の範囲から適宜選ぶことができる。
本実施形態の成形品は、種々の用途、例えば、各種保存容器、電気・電子機器部品、オフィスオートメート(OA)機器部品、家電機器部品、機械機構部品、車両機構部品、車載用筐体部品などに適用でき、車載用筐体部品に好ましく用いられる。
成形品の製造方法は、特に限定されず、熱可塑性樹脂を含む樹脂組成物について一般に採用されている成形法を任意に採用できる。その例を挙げると、射出成形法、超高速射出成形法、射出圧縮成形法、二色成形法、ガスアシスト等の中空成形法、断熱金型を使用した成形法、急速加熱金型を使用した成形法、発泡成形(超臨界流体も含む)、インサート成形、IMC(インモールドコーティング成形)成形法、押出成形法、シート成形法、熱成形法、回転成形法、積層成形法、プレス成形法、ブロー成形法等が挙げられ、中でも射出成形が好ましい。
射出成形の詳細は、特許第6183822号公報の段落0113~0116の記載を参酌でき、これらの内容は本明細書に組み込まれる。
実施例で用いた測定機器等が廃番等により入手困難な場合、他の同等の性能を有する機器を用いて測定することができる。
表1-1における再生炭素繊維の残渣は、再生炭素繊維中の炭化物の量を示している。すなわち、本実施例で用いる再生炭素繊維は、樹脂(例えば、エポキシ樹脂)と炭素繊維の複合物の焼成物であるため、再生炭素繊維には樹脂(例えば、エポキシ樹脂)由来の残渣(炭化物)が含まれている。樹脂残渣の量は、加熱処理前の炭素繊維強化樹脂に含まれる炭素繊維質量を炭素繊維含有率から算出し、式(X)から求めた値である。単位は、質量%で示している。
[B - (A × C)/(B)]× 100 式(X)
A:加熱処理前の炭素繊維強化樹脂の質量
B:加熱処理物の質量
C:加熱処理前の炭素繊維強化樹脂の炭素繊維含有率
<樹脂組成物(ペレット)の製造>
表3~5に示すように、再生炭素繊維およびバージン炭素繊維以外の成分を撹拌混合した。表3~5の各成分は質量部表記である。得られた混合物を、1ベントを備えた2軸押出機のメインホッパーに投入し、再生炭素繊維またはバージン炭素繊維はサイドフィーダーより供給し、結晶性熱可塑性樹脂の溶融温度の温度条件にて、スクリュー回転数250rpm、吐出量200kg/時間の条件で混練してストランド状に押し出し、樹脂組成物のペレットを得た。
尚、比較例2は、サイドフィーダーによる再生炭素繊維の安定投入が不可能であったため、所定の樹脂組成物(ペレット)を得ることができなかった。
スクリュー回転数250rpm、吐出量200kg/時間の条件において、樹脂組成物のペレットが得られたか否かを以て生産性の判断を行った。5人の専門家が行い、多数決で判断した。
A:樹脂組成物のペレットを得ることができた

ISO1183に準拠し、比重を測定した。また、以下の通り判定した。

上記で得られたISO曲げ試験片(厚さ4mm)をISO178に従って曲げ最大強さおよび曲げ弾性率を測定した(単位:MPa)。
上記で得られたISO多目的試験片を用い、ISO179-1およびISO179-2に従い、23℃におけるシャルピー衝撃強さ(ノッチ付き)の測定を行った。単位は、kJ/m2で示した。
上記曲げ最大強さに基づき、機械的強度を以下の通り判定した。
A:曲げ最大強さが190MPa以上
B:上記A以外
上記で得られた樹脂組成物のペレットを120℃で7時間乾燥させた後、射出成形機(住友重機械工業社製「SE50DUZ」)を用い、樹脂温度250℃、金型温度80℃の条件下で射出成形を行い、長さ127mm、幅12.7mm、肉厚1.0mm、および、長さ127mm、幅12.7mm、肉厚1.5mmのUL試験用試験片を得た。
得られたUL試験用試験片を、23℃、相対湿度50%の恒温室の中で48時間調湿し、米国アンダーライターズ・ラボラトリーズ(UL)が定めているUL94試験(機器の部品用プラスチック材料の燃焼試験)に準拠して試験を実施した。
UL94試験とは、鉛直に保持した試験片にバーナーの炎を10秒間接炎した後の残炎時間やドリップ性から難燃性を評価する方法であり、V-0、V-1およびV-2の難燃性を有するためには、以下の表2に示す基準を満たすことが必要となる。
