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 aluminum extrusion pressing machine. Also disclosed is a heat resistant pad coated and impregnated with a silicone resin to improve wear resistance and impact resistance.
Claims3
In an aluminum extrusion process, the improvement comprising receiving the hot extruded aluminum onto a heat resistant pad comprising a plurality of batt layers, each batt layer consisting essentially of carbon fibers admixed with aromatic polyamide fibers, said batt layers being superimposed one on another and entangled into an integral felt-like structure by needle punching.
