Claims35
A method of forming an impact absorbing composite, the method comprising:
- placing a flexible layer into a molding apparatus, the molding apparatus having a plurality of first surfaces that define a plurality of first mold cavity portions and a second surface that defines a second mold cavity portion and, the flexible layer positioned between the first mold cavity portions and the second mold cavity portion, and the first mold cavity portions and the second mold cavity portion collectively forming a mold cavity;
- placing polymeric resin in the mold cavity;
- expanding the polymeric resin in the mold cavity to form an impact absorbing composite intermediate, the impact absorbing composite intermediate comprising expanded polymeric resin and the flexible layer;
- and
- finishing the impact absorbing composite intermediate to form the impact absorbing composite.
