Apparatus for molding and hardening resinous composite structure

Abstract

Abstract PURPOSE:To provide the titled apparatus that carries out heating and cooling according to prescribed conditions, by providing adjusting means for detecting and controlling the temperature, the pressure and the state of a resin when a resinous composite structure is molded under pressure and heating in an autoclave by using a bag. CONSTITUTION:Preliminarily molded items W are layered on a molding jig 2 of the molding and hardening apparatus 1. The top of the items W is covered with the vacuum bag 3 of a soft film whose inside is made airtight by sealing members 4 and is applied with vacuum by a vacuum pump 6. The drum inside temperature adjusting apparatus 7 comprises a cooler 8, a heater 9 and a fan 10. The heating apparatus 12 comprises a multi-heater 13 embedded in the jig 2 and heaters 14 that are embedded in for example a heat-resistant rubber mat and will cover the items W. The resin state detector 40 is provided for detecting the time when the resin in the items W initially flows and the time when it starts to gel. The controller 16 controls the signals of the above-mentioned channels to supply electric power to valves.
