Abstract
Description
本実施形態において、活性水素成分は、アルキルチオ基を有する芳香族ジアミン(A)を含む。アルキルチオ基を有する芳香族ジアミン(A)としては、芳香環に直接結合した2つのアミノ基とともに、芳香環に直接結合したアルキルチオ基を有する化合物が好ましい。アルキルチオ基は−SCnH2n+1(ここで、nは1以上の整数であり、好ましくは1〜5の整数)で表される基である。芳香族ジアミン(A)は、一分子中にアルキルチオ基を1つ有してもよく、2つ又はそれ以上有してもよい。好ましくは、芳香環に直接結合した2つのアルキルチオ基を有することである。
本実施形態において、ジイソシアネート成分は、脂肪族ジイソシアネート、脂環式ジイソシアネートおよびこれらの変性体からなる群から選択された少なくとも一種のジイソシアネート(B)を含む。このようなジイソシアネート(B)を用いることにより、上記芳香族ジアミン(A)との組み合わせにより、成形時の低い樹脂粘度と高いガラス転移温度を両立することができる。特に脂肪族ジイソシアネートまたはその変性体を用いることにより、得られる樹脂の引張破壊ひずみをより高めることができる。また、脂環式ジイソシアネートまたはその変性体を用いることにより、得られる樹脂のガラス転移温度をより高めることができる。
本実施形態に係る二液硬化型組成物は、上記活性水素成分と上記ジイソシアネート成分とを含むものであり、これら活性水素成分とジイソシアネート成分との反応により熱可塑性樹脂が生成されるものである。すなわち、該二液硬化型組成物は、反応生成物が熱可塑性樹脂になるという性質を持つものである。二液硬化型組成物は、活性水素成分を第1液とし、ジイソシアネート成分を第2液として、これら第1液と第2液を混ぜ合わせることにより両成分を反応硬化させることができる、二液硬化性の樹脂組成物である。
本実施形態に係るマトリックス樹脂は、上記活性水素成分と上記ジイソシアネート成分との反応物を含む熱可塑性樹脂であり、一実施形態として上記二液硬化型組成物を硬化させることにより得られる。活性水素成分にジオール(C)が含まれない場合、得られる樹脂は熱可塑性ポリウレア樹脂であり、活性水素成分にジオール(C)が含まれる場合、得られる樹脂は熱可塑性ポリウレタン・ウレア樹脂である。ここで、熱可塑性ポリウレタン・ウレア樹脂は、主鎖にウレタン結合とウレア結合の両方を含む樹脂である。
本実施形態に係る繊維強化複合材料(FRP)は、上記した二液硬化型組成物の硬化物またはマトリックス樹脂と、強化繊維と、を含むものである。
本実施形態であると、成形時の樹脂粘度が低いにもかかわらず、高いガラス転移温度を有する熱可塑性樹脂を提供することができる。成形時の樹脂粘度が低いことにより、強化繊維と複合化させる際のマトリックス樹脂の流動性を向上して、成形作業性を向上することができる。
