Rod-reinforced cushion beam

摘要

A rod-reinforced cushion beam includes a rigid frame having a spaced of main rod members and a longitudinally paced plurality of connecting elements; and a plastic body encapsulating substantially solidly filling the frame. At least some of the transverse elements are shear panels. A preferred embodiment has least 90 percent by weight of the plastic body in a main polymeric component of linear low density polyethylene, and an additive component that does not contain filler material. Also disclosed is a method for forming a rod-reinforced cushion beam.
