Abstract
The present invention relates generally to composite materials and to methods of manufacturing the composite materials. In particular, the composite material of the present invention utilizes combinations of continuous fibers in the form of loops, chopped fibers, woven fibers and foams.
Claims9
A composite, comprising:
- a material matrix, comprising:
- at least one layer of chopped fiber having a first edge and a second edge;
- at least one layer of unidirectional fiber having a first edge and a second edge, wherein the layer of unidirectional fiber is longer than the layer of chopped fiber;
- and
- at least one layer of a woven roving having a first edge and a second edge, wherein the layer of woven roving is longer than the layer of unidirectional fiber;
- and
- a foam core,
- wherein each layer is secured around the foam core such that the first edge and the second edge of each of the layers are staggered respective to the first and second edge of any other layer such that the edges do not produce a single seam over the length of the composite.

A composite, comprising:
- a foam core,
- at least one layer of chopped fiber having a first edge and a second edge, said layer of chopped fiber being disposed about said foam core;
- at least one layer of unidirectional fiber having a first edge and a second edge, said layer of unidirectional fiber being disposed about said foam core;
- and
- at least one layer of a woven roving having a first edge and a second edge, said layer a woven roving being disposed about said foam core;
- and
- wherein each layer is secured around the foam core such that the first edge and the second edge of each layer are staggered respective to the first and second edge of any other layers such that the edges do not produce a single seam over the foam core.
