ABSTRACT OF THE DISCLOSURE An improved fiber reinforced polyoxymethylene molding composition is provided which when molded forms a composite article having improved physical properties (e.g. tensile strength and Izod impact strength). In admixture with the polyoxymethylene polymer and fibrous reinforcement (e.g. glass fiber) is provided a minor amount (as defined) of a certain poly- carbodiimide (as defined) or a combination of the polycarbodiimide and a high molecular weight thermoplastic phenpoxy resin. It is believed that the polycarbodiimide either alone or in combination with the thermoplastic phen- oxy resin function primarily by a complex mechanism which is incapable of simple explanation to enhance the adhesion between the chemical functional- ity of the oxymethylene polymer chain and the fibrous reinforcement.
