Title:
現場重合型熱可塑性プリプレグ、熱可塑性コンポジット及びその製造方法
Document Type and Number:
Japanese Patent JP6440222
Kind Code:
B2
Abstract:
Methods for manufacturing an in-situ polymerized type thermoplastic prepreg, which is excellent in productivity has tack properties and drape properties that allow easy shaping in a mold, is excellent in handling properties, and allows a molded product obtained by curing to have both mechanical properties as high as those of a thermosetting composite and the features of the thermoplastic composite. The method comprises (a) preparing an in-situ polymerized thermoplastic epoxy resin having two functional groups, applying it onto a release sheet while adjusting the temperature of the resin at 40-70°C, polymerize to cure to the B-stage while maintaining the temperature of the resin at 25-40°C for 50-240 hours and impregnating the reinforcing fibers or (b) preparing an in-situ polymerized thermoplastic epoxy resin having two functional groups, polymerize to cure to the B-stage while maintaining the temperature of the resin at 25-40°C for 50-240 hours, applying it onto a release sheet while adjusting the temperature of the resin at 40-80°C and impregnating the reinforcing fibers.
