Method of manufacture of an energy absorbing beam

摘要

An energy absorbing beam is shown which may be manufactured by wrapping several side-by-side strands of resin coated filaments about an increasing number of pins mounted upon a base. The base then becomes part of a mold to which heat and pressure is applied for forming the coated filaments into a beam having a variable cross section with variable thickness. Devices for fastening the beam may be molded into the beam by passing the coated filaments about the fasteners as the filaments are wrapped about the pins.
