PRODUCTION OF SANDWICH PANEL MADE OF FIBER REINFORCED THERMOPLASTIC RESIN

摘要

PURPOSE:To efficiently and continuously produce a thermally shapable sandwich structure made of a fiber reinforced thermoplastic resin. CONSTITUTION:A room temp. or heat polymerizable thermoplastic resin precursor whose viscosity is 10-10<4> centipoise and a reinforcing fiber fabric are brought to a contact state and the resin precursor is infiltrated in the fabric to form a fiber reinforced thermoplastic resin precursor. This resin precursor is bonded to the upper and rear entire surfaces of a core material and the whole is polymerized and cured at room temp. or/and at high temp.
