Abstract
Description
前述した通り、本発明は複合材料繊維マットを利用した繊維強化複合材料の製造方法及び前記繊維強化複合材料の製造装置を提供する。本発明では複合材料のマトリックスとして粉末状或いはペレット状の熱可塑性樹脂の代りに、熱可塑性繊維を使用する。そのような熱可塑性繊維を強化用繊維と高速でマット化して複合材料マットを形成する。前記マットを貯蔵するか又は搬送後にも、望む時点に何時でも繊維強化複合材料シートへの成型が可能である。さらに、一様に繊維が分散した複合材料マットを成型して得た本発明の繊維強化複合材料シートは、強化用繊維とマトリックス樹脂間の均一な接着強度により界面接着性が優れている。結果的に高強度の繊維強化複合材料を製造することでできる。
