ABSTRACT OF THE DISCLOSURE As is seen particularly in Figure 3, a composite piston (10) for internal combustion engines is provided. The base structure of the piston is formed from a fiber- reinforced resin material. Covering the head portion (11) of the base structure and integral therewith is a cap por- tion (14) formed of a nonflammable material such as metal, metal alloys and ceramics. The cap (14) and head portion (11) of the piston have an outer diameter which is less than the outer diameter of the piston body by an amount suf- ficient to accommodate for the difference in the thermal coefficient of expansion of the material of the cap and the material of the base structure.
