Beschreibung
Zusammenfassung:	A structural member comprises a plastic base material with fiber reinforced plastic fill material. A gas producing substance or foaming agent is mixed with the base material and provides a lower density within the interior of the member. The structural member can comprise one or more of the components of a utility pole assembly, such as the crossarms, bracing, insulators and pole. A method of producing the structural member includes the steps of mixing additives with plastic pellets for feeding into an extruder. The extruded structural members are formed, cooled, pulled and cut to desired lengths.
