ABSTRACT:
A dowel for use in the woodworking industry to secure two pieces of wood together is made of a composite, polymeric material comprising from about 4% to 90% by weight thermosetting resin and from about 10% to 96% by weight fibrous filler material. The thermosetting resin and the fibrous filler material are mixed together and then subjected to a high pressure and an elevated temperature to set the thermosetting resin and form a dense, hard mass of composite, polymeric material which is formed into the cylindrical shape of a dowel. The dowels have a surface that will adhere to conventional glues used in the woodworking industry.
