Abstract
A method of forming a cross-car beam is provided. A composite is melted to form a viscous polymer. The polymer is injected into a mold. Pressurized fluid is injected into the mold to evacuate a portion of the viscous polymer from the mold and to form a channel therethrough. The remaining viscous polymer is cooled within the mold to form a cross-car beam.
Claims14
A method of forming a cross-car beam, comprising the steps of:
- melting a composite material to form a viscous polymer;
- injecting the viscous polymer into a mold;
- injecting a pressurized fluid into the mold to evacuate a portion of the viscous polymer from the mold and to form a narrow channel therethrough to accommodate a greater load stress, wherein the channel has first and second ends and defines a hollow chamber therebetween;
- and
- cooling the remaining viscous polymer within the mold to form a cross-car beam.

The method of forming a cross-car beam, comprising the steps of:
- melting a composite material to form a viscous polymer;
- injecting the viscous polymer into a mold, the mold comprising a cavity that remains unfilled with viscous polymer;
- injecting a pressurized fluid into the mold in order to force a portion of viscous polymer into the cavity to form a narrow channel enclosed by a layer of solid composite material, wherein the narrow channel is configured to accommodate a greater load stress;
- and
- cooling the viscous polymer within the mold to form a cross-car beam.
