Abstract

PURPOSE: To provide the titled molding material having excellent mechanical strength and heat resistance, consisting of a phenolic resin and a gypsum fiber treated with aminosilane and/or epoxysilane.
CONSTITUTION: A gypsum fiber (a) having a diameter of 1W10μm and a length of 40W400μm, is sprayed with a soln. (b) of 1W3wt% (based on the weight of the component a) aminosilane and/or epoxysilane dissolved in 5W10wt% (based on the weight of the component a) solvent (e.g. methanol or water) to produce a silane- treated gypsum fiber (B). Then 50W200pts.wt. component B and, if necessary, a hardener (e.g. hexamethylenetetramine), a curing aid [e.g. Ca(OH)2], a lubricant, a glass fiber, etc. are blended with 100pts.wt. novolak type phenolic resin (A). The mixture is kneaded by using heating roll.
