Abstract
Description
複雑形状の成形が可能な短繊維強化熱可塑性複合材料は既に実用化されているが、強化繊維の繊維長が短いため、軽金属と比較すると著しく低弾性率になってしまう問題がある。この為、連続繊維で強化した熱可塑性樹脂組成物が強く望まれている。
例えば、特許文献1には炭素繊維に電解処理を施すことにより、界面接着性の指標である層間剪断強度を向上させる方法が提案されているが、該炭素繊維で強化された熱可塑性樹脂複合材料の機械的特性は、充分とは言えないものであった。
すなわち本発明は、以下に示すものである。
本発明で使用される、連続強化繊維(A)には、ガラス繊維、炭素繊維(例えば、PAN系炭素繊維、ピッチ系炭素繊維など)又はアラミド繊維等が挙げられ、弾性率の点から炭素繊維が好ましい。
連続強化繊維(A)の繊維長は平均10mm以上であるものが好ましく、成形後の成形品よりも長い繊維を使用することがより好ましい。
また、連続強化繊維の形態としては、一方向シート、織物シート、多軸積層シート等が挙げられ、具体例としては以下に示されるが、本発明を限定するものではない。
アラミド繊維:(帝人社製)トワロン
炭素繊維:(有沢製作所社製)CFP3113
本発明に用いられる熱可塑性樹脂(B)は、シアノ基含有ビニルモノマー(c1)及び芳香族系ビニルモノマー(c2)の共重合体(C)を含有する。ここで、シアノ基含有ビニルモノマー(c1)及び芳香族系ビニルモノマー(c2)の共重合体(C)とは、モノマー(c1)及びモノマー(c2)を含むモノマー混合物より生成する共重合体を意味し、そのモノマーの配列には、特に限定はなく、ランダム、ブロック、グラフト、交互などであってよい。
共重合体(C)100質量%において、シアノ基含有ビニルモノマー(c1)の割合は、15質量%~45質量%であってよく、機械的特性の理由から20質量%~40質量%であることが好ましい。すなわち、共重合体(C)を生成するモノマー混合物中のモノマー成分の合計に対して、シアノ基含有ビニルモノマー(c1)の割合が、15質量%~45質量%であってよく、20質量%~40質量%であることが好ましい。
共重合体(C)100質量%において芳香族系ビニルモノマー(c2)の割合は、55質量%~85質量%であってよく、機械的特性の観点から60質量%~80質量%であることが好ましい。すなわち、共重合体(C)を生成するモノマー混合物中のモノマー成分の合計に対して、芳香族系ビニルモノマー(c2)の割合が、55質量%~85質量%であってよく、60質量%~80質量%であることが好ましい。
共重合体(C)を生成するモノマー混合物には、任意のビニル系モノマーを含んでいてもよい。そのようなビニル系モノマーとして、エチレンプロピレンジエン、アクリル酸エステル、2-クロロエチルビニルエーテルなどが挙げられる。好ましくは、共重合体(C)は、シアノ基含有ビニルモノマー(c1)及び芳香族系ビニルモノマー(c2)のみから生成される共重合体である。
より具体的には、日本エイアンドエル社製ライタック-A 100PCF/120PCF、テクノポリマー社製サンレックス SAN-C/SAN-R/SAN-H/SAN-L/SAN-T、ダイセルポリマー社製セビアン-N 020/020SF/050/050SF/070SF/080SF、旭化成ケミカルズ社製スライタックAS 767/T8701/769/789/783/T8707/CS747、東レ社製トヨラックA20C-300/A25C-300などのいわゆるAS樹脂もしくはSAN樹脂が挙げられ、市販品を容易に入手することができる。ただし、発明の効果を奏する限りにおいて、これらに限定されない。
熱可塑性樹脂(B)100質量%中の上記共重合体(C)の割合は50質量%~100質量%であってよく、80質量%~100質量%のものが安価な複合材料が得られるため好ましい。
例えば耐熱性や耐薬性などの改善を目的としたエンジニアリングプラスチックやスーパーエンジニアリングプラスチックなど(ポリカーボネート、ポリアミド、ポリエステルなど)を加えてAS樹脂、AES樹脂、ASA樹脂などのアロイとして用いることが出来る。
これらの成分の熱可塑性樹脂(B)100質量%中の割合は0~50質量%であってよく、0~20質量%のものが安価な複合材料が得られるため好ましい。
共役ジエン成分とはひとつの単結合によって二重結合が隔てられ、共役したジエンを持つモノマーであり、例えばブタジエン、イソプレンなどが挙げられる。
共重合体(C)中の共役ジエン成分が10質量%より多いと、曲げ強度が低下する。
本発明の繊維強化熱可塑性樹脂組成物中の連続強化繊維(A)と熱可塑性樹脂(B)の割合は、繊維強化熱可塑性樹脂組成物100質量%において、連続強化繊維(A)1質量%~80質量%、熱可塑性樹脂(B)20質量%~99質量%であってよく、繊維強化熱可塑性樹脂組成物の機械的特性の観点から、好ましくは、連続強化繊維(A)40質量%~75質量%、熱可塑性樹脂(B)25質量%~60質量%である。
この範囲よりも強化繊維の割合が少ない場合、繊維強化熱可塑性樹脂組成物の機械的特性は軽金属と同等以下となってしまい、強化繊維割合がこの範囲よりも多い場合では、樹脂量が少なく、マトリックス樹脂による強化繊維の集束作用が機能せず、機械的特性が低下する。

CFRTPにおいてマトリックス樹脂をAS樹脂にした場合、マトリックス樹脂がPS樹脂である場合と比較して、曲げ強度が向上する(実施例1、比較例2)。これは、AS樹脂に含まれるシアノ基が曲げ強度の向上に寄与していると考えられる。
