Ultra-drawn polyethylene fibre reinforced composite material and method of manufacturing same.

摘要

The present invention relates to an ultra-drawn polyethylene fibre reinforced composite material having the ultra-drawn polyethylene fibres as the reinforcement material and the epoxy resin as the matrix resin, wherein the epoxy resin is modified with an elastomer to improve adhesion with the ultra-drawn polyethylene fibres. Such improvement in adhesion is ascribable to the fact that low polarity portions are formed in the epoxy resin by introducing the elastomer to raise affinity with ultra-drawn polyethylene fibres, and that the low polarity portions are formed into domains with a specific shape according to types of elastomer employed to effect intercation by a shape effect with the surface micro-structure of the fibres.
