The invention provides a method of forming structural components for
automotive vehicles from elongated tubular blanks. A longitudinally
oriented tubular blank comprised of a thermoplastic material is provided.
The tubular blank is fluidformed in a fluid forming cavity by orienting
in a hoop direction of the tubular blank to conform the tubular blank to
a predetermined shape of the fluid forming cavity to provide structural
components having increased strength over the tubular blank. The
structural components have biaxial and/or triaxial orientation. Fluid
forming is performed within an orientation temperature range above the
glass transition temperature and below the softening point of the
thermoplastic material. Structural components include bumper beams,
intrusion beams in vehicle doors, crush cans, and frame members. The
produced structural components are strong and light weight.
