A structural member is provided which is heat resistant and is formed from a mixture of poly(phenylene sulfide) resin and a filler with the structural member being comprised of an inner core formed from the poly(phenylene sulfide) and filler with the inner core having a cellular structure. The inner core is coated with poly(phenylene sulfide) which is fused and cured to provide additional strength for the member and to seal the porous inner core. Preferably, the structural member is of a honeycomb type having a plurality of voids to further lighten the member. Laminate members can be bonded or otherwise secured to the member to form a laminate type structure. The inner core portion of the structural member is made by molding the mixture and curing same to a predetermined degree of cure, after which the core portion is coated with a coating of poly(phenylene sulfide) which is then fused and cured.
