ABSTRACT:
A fiber reinforced structure having a hollow blow-molded core and a method for manufacturing the same. Bulk fibrous material is dispensed between two die pieces of a mold. A blow-moldable plastic parison is extruded within the fibrous material. The mold is closed, pinching the parison closed and detaching the bulk fibrous material from the structure. The parison is inflated thus forcing the fibrous material against the interior mold walls. Liquid resin is injected into mold and impregnates the fibrous material. After curing, the finished reinforced structure is removed from the mold.
