PROBLEM TO BE SOLVED: To obtain a phenolic resin molding material having a high mechanical strength and excellent abrasion resistance by using a phenolic resin, glass fibers and a tetrafluoroethylene resin powder as the essential components and specifying the contents of the glass fibers and the tetrafluoroethylene powder. SOLUTION: This material comprises novolac phenolic resin precondensate or a resol phenolic resin precondensate obtained by reacting a phenol (e.g. phenol or cresol) or a phenol modified with molasses, lignin, xylene or the like with an aldehyde (e.g. formalin or paraformaldehyde) in the presence of a catalyst or a phenol resin being a combination thereof, 5-50wt.%, based on the entire molding material, glass fibers being chopped strands used as a molding material and 0.1-20wt.%, based on the entire molding material, fine tetrafluoroethylene resin powder having a mean-particle diameter of 10-50μm and a maximum particle diameter of 50-100μm.
