Abstract
Disclosed herein is a heat resistant pad which comprises a plurality layers of batt mixtures essentially consisting of carbon fibers and aromatic polyamide fibers, the layers of batt mixtures being superposed and entangled to integrate into a felt-like structure by way of needle punching. A heat resistant pad of such constitution has a property of adequate flexibility, wear resistance, impact resistance, frictional coefficient and cushioning property for use with rear facilities of an aluminium extrusion pressing machine. Also disclosed is a heat resistant pad coated and impregnated with a silicone resin to improve wear resistance and impact resistance.
