A method of making a composite having end walls, the method comprising:
- inserting a flowable material into a first mold half having a predetermined shape and structures to create a core having end walls;
- placing continuous fibers into the first mold half such that the fibers are oriented proximate the structures that create the end walls such that the continuous fibers will orient along the ends of the composite;
- allowing the flowable material to solidify so that the composite can be removed from the first mold half.
A method of making a composite having end walls, the method comprising:
- providing a first mold half having structures to create a core having end walls;
- providing a second mold half having structures to create a core having end walls;
- placing continuous fibers in the first mold half such that the fibers are oriented with the end wall structure such that the continuous fibers will orient along the ends of the composite;
- compressing the second mold half and the first mold half;
- injecting a flowable material between the two mold halves;
- allowing the flowable material to solidify;
- and removing the composite from the first mold half.

A method of making a composite having end walls, the method comprising:
- creating a screen of continuous fibers;
- placing a flowable material onto the screen of continuous fibers;
- placing the screen and flowable material into a first mold half having a predetermined shape and structures to create a core having end walls such that the fibers are oriented proximate the structures that create the end walls such that the continuous fibers will orient along the ends of the composite;
- allowing the flowable material to solidify so that the composite can be removed from the first mold half.
