Abstract
The present invention provides a composite of a thermosetting resin with a metallic oxide, prepared by a process which comprises subjecting a metal alkoxide containing a silicon alkoxide and/or a low condensate thereof to hydrolysis and polycondensation in a solution of a phenolic resin and/or thermosetting resin containing a phenolic resin while effecting the removal of the solvents and/or curing reaction of the resins to incorporate a particulate metallic oxide having an average particle diameter of from 0.01 to 5 .mu.m homogeneously in said thermosetting resin with a good interfacial wettability without causing macroscopic phase separation. Thus, the present invention can provide a cured or uncured composite of a thermosetting resin with a metallic oxide which can be used as a molding material, sliding material, friction material, coating material, film-forming material, etc.
