Abstract
Description
そのためFRPと非連続繊維強化熱可塑性複合材を張り合わせて一体化することにより、複雑形状を持つ成形品の成形性と生産性を高めることが提案されている。
テープ状プリプレグは強化繊維が一軸方向に配列しているので、テープ状プリプレグの配置方向は極めて重要である。本発明における連続繊維強化熱可塑性複合材料はテープ状プリプレグから得られる織物または多軸積層布によって構成される。織物とはテープ状プリプレグを縦、横に織り込んだもので、強化繊維の方向が縦と横方向に配列している。
一方、多軸積層布とはテープ状プリプレグが縦、横以外に、例えば縦方向に対して45度傾いた方向にテープ状プリプレグを配列したものである。この多軸積層布は、成形する製品で最も強度が必要とする方向にテープ状プリプレグを配列することが出来るので、強化繊維の補強効率が最もすぐれた強化形態である。また、原理的には360度、全方向に強化繊維を配列した多軸積層布を製作することが可能である。
テープ状プリプレグの切断する長さは10mm〜60mmであり、好ましくは20mm〜50mmである。強化繊維はテープ状プリプレグの長さ方向に配列されているため、短冊状に切断されたテープ状プリプレグの長さが強化繊維の長さとほぼ等しくなる。
切断する長さが10mm以下では強化繊維の補強効率が低く好ましくない。一方、切断する長さが60mm以上では成形品のリブやボス等の突起物に強化繊維が均一に流入することが困難になる場合が多い。特にリブ等の先端が1〜2mmと薄い場合や50mm以上の長いリブやボスを持つ成形品においては、繊維の流入が少なくなり、リブ先端部の補強効果が低下する場合があり好ましくない。
本発明の非連続繊維強化熱可塑性複合材料では成形品の突起物の形状、大きさおよび高さ等の形状によって、2種類以上の長さの短冊状テープ状プリプレグを使用することも出来る。
本発明の製造法は特に限定されるものではないが、次のような工程で成形品の製造を行うことが出来る。テープ状プリプレグを所定に長さに切断した短冊状の薄片を、リブやボス等の突起物を形成する金型の下型にランダムな向きに配列させてチャージする。特にリブやボスの大きさや深さによって、テープ状プリプレグの切断した短冊状の長さや下型にチャージするプリプレグの量等を調節する必要がある。
次に、その上にテープ状プリプレグから得られた織物または多軸積層布を少なくとも1層積層した後、上型を閉じ、電磁誘導加熱によって熱可塑性樹脂の融点より高い温度まで加熱し、所定の圧力下で保持した後、冷却水により金型を冷却することにより成形品を取り出すことが出来る。
本発明において製造法は特に限定されるものではないが、電磁誘導加熱によってチャージしたプリプレグを加熱溶融する方式は、金型に材料をチャージする際の材料の取り扱いのし易さ等で好ましい製造方法である。勿論、連続繊維強化および非連続繊維強化の複合材料をそれぞれ、あらかじめシート状材料にしておき、別々に加熱溶融することにより、従来のスタンピング成形により、一体成形することもできる。
また以下に実施例、比較例において示した試料や物性値は、下記のような試料の作製法や試験法で行った。
・連続繊維強化熱可塑性複合材料はガラス繊維を強化材とし、熱可塑性樹脂にマレイン酸変性ポリプロピレンを使用し、体積含有率Vfが50%のテープ状プリプレグを用い、多軸積層布を作製した。
・非連続繊維強化熱可塑性複合材料はガラス繊維を強化材とし、熱可塑性樹脂にマレイン酸変性ポリプロピレンを使用し、体積含有率Vfが50%のテープ状プリプレグを用い、30mmの長さに切断した短冊状のプリプレグを使用した。
・成形品は図1に示した「リブ付き平板」の金型を使用し、上記の連続繊維強化熱可塑性複合材料および非連続繊維強化熱可塑性複合材料を金型のキャビティーに装入し、上型を閉じて、電磁誘導加熱で約250℃に加熱、加圧した後、金型を冷却して成形品を取り出した。
・成形品の曲げ強度は成形品の図1に示したa、b、c、dの各部位から試料を切り出し、ISO178に準じて測定した。
・ガラス繊維の体積含有率Vfは図1に示したa、b、c、dの各部位から試料を切り出し、電気炉で625℃に加熱し、樹脂成分を完全に除去した後、残ったガラス繊維の重量から計算して測定した。
評価結果は表1に示した。
比較例1では成形品の平板部分は主にテープ状プリプレグで織った織物(平織)のみからなる成形品である。織物の補強効果が高いため、平板部分を示すa部位の強度は高い。しかしながら、リブ部分に強化繊維が入り込めないため、b部位ではガラス繊維の体積含有率Vfが20%となり、更にc部位やd部位ではガラス繊維の体積含有率Vfが0%となり、樹脂のみの強度しか得られなかった。
比較例2では非連続繊維強化熱可塑性複合材料である30mmの長さに切断されたテープ状プリプレグからなる成形品である。流動性が優れるため、リブ部分にも強化繊維が充填されている。しかしながら、最も強度を必要とするa部位の平板部分では強度が低く、織物によって補強された成形品に対して著しく見劣りがする。
