Abstract: An elongate composite structural member and method of making the same which is particularly useful for forming the handle of hand-held striking and prying tools or implements. The elongate structure member comprises a foamed in place molded resin composition core and outer skin layer which is reinforced with intermediate layer of structurally strong, unidirectional oriented fibers. The expanded foam resin, intermediate fiber layer and the expanded foam resin outer skin are bound together by the cured foamed resin composition formed during the molding process to form a strong, integral composite structure.

Abstract: A molded, composite, airfoil-defining, synthetic resin blade for large diameter cooling tower fans is disclosed wherein a moderately dense synthetic resin foam core is first formed that is generally of the same size and shape as the final desired blade. A shank embedded in the foam core extends outwardly from the end of the blade that is adapted to be fastened to the fan hub. A skin of fiberglass reinforced synthetic resin material is placed over the foam core with the thickness of the skin being greatest at the hub end of the blade and especially around the shank. The foam core with the skin thereon is molded into the final desired configuration thereof under pressure and temperature conditions such that the core is compressed and the thickness reduced to an extent correlated with the thickness of the synthetic resin skin on opposite faces thereof.
