Abstract
A motor vehicle body including inner and outer body panels. The inner body panel and the outer body panel form at least one cavity therebetween. A structural cross woven fiber material is applied to the cavity formed between the inner and outer body panels in order to increase rigidity of the motor vehicle body. The cross woven or unidirectional fiber is fiberglass carbon fiber or other structural fibers which, in combination with resin (in fiber or powder form), becomes an integral part of the motor vehicle body structure when heat is applied.
Claims11
A motor vehicle body structure, comprising:
- an outer body panel;
- an inner body panel mounted to said outer body panel and forming at least one cavity therebetween;
- and
- a structural fiber material applied to said cavity to enhance rigidity of the motor vehicle body wherein the structural fiber material is a cross-weaver of unidirectional structural fiber which is selected from the group of carbon and graphite fibers, metal, cotton, carbon based fibers and combinations thereof,
- wherein the structural supporting fiber material further comprises multiple filaments cross woven with a narrow weave angle.
A motor vehicle body, comprising;
- a left-hand outer body panel;
- a left-hand inner body panel;
- a right-hand outer body panel;
- a right-hand inner body panel;
- the four body panels being capable of being secured together to form a motor vehicle body having a longitudinal midline, the four body panels being securable together at the longitudinal midline of the motor vehicle body;
- the two inner body panels and the two outer body panels forming at least one cavity therebetween;
- and
- the supporting woven fiber material disposed in the cavity, and combined to form an integral part of the motor vehicle body when heat is applied to provide structural support to the four body panels, thereby increasing the rigidity.
