Bumper component made of fiber-reinforced material for automobiles or the like

摘要

A vehicle bumper bar is made of at least one completely closed box shaped body wound of fiber-reinforced synthetic resin impregnated strands or bands with a fiber orientation that may vary along the length of the bar and also from one wall of the box shape to the other. Several bodies of closed cross-section may be bonded together, for example by the resin curing, to form a single integral body of approximately square configuration. Towing elements may be integrated directly into the bar.
