MELT IMPREGNATION FORMATION OF THERMOFORMABLE THERMOPLASTIC/KNITTED GLASS CLOTH COMPOSITES

摘要

MELT IMPREGNATION FORMATION OF THERMOFORMABLE THERMOPLASTIC/KNITTED CLASS CLOTH COMPOSITES Disclosed is a method for making thermoformable glass fiberreinforced composite suitable for thermoforming into an aircraft interior part where deep draws are required. The method comprises placing within a press a sheet of a polyetherimide and a sheet of knitted glass cloth. The sheet within the press then is subjected to sufficient pressure and temperature to melt impregnate the knitted glass cloth with a polyetherimide to form a thermoformable composite thereof.
