Abstract

Abstract: For polyimide resins with a temperature of 375 ℃ for the thermos-pressor tank-vacuum bag molding curing temperature, the single-layer vacuum bag package system is often broken in the curing process because the curing temperature is close to the temperature limit of high temperature vacuum bag and high temperature sealing material. Dual vacuum package cured parts by non-destructive testing, glass transition temperature and with the furnace part bending and layer shear performance test, in line with the standard requirements, indicating that the dual vacuum package is reasonable and feasible.

Key words: autoclave curing process, polyimide, seal, composites
