Abstract:
A method of making a carbon fiber composite material, comprising the steps of:formig a carbon fiber sample from a series of carbon fibers and a resin material applied to the carbon fibers;as the carbon fiber sample is formed, randomly altering the carbon fiber sample to disrupt any pattern being formed to the carbon fiber sample and insure the composite material will have a non-uniform, random appearance, wherein the step of randomly altering the carbon fiber sample comprises introducing physical disruptions to the formation of the sample, selected from the group consisting of varying rates at which the fibers are applied, introducing pieces of fibrous materials on the fibers of the sample, varying the thickness of the fibers forming the sample, varying the tension on the fibers as the fibers are formed into the sample, varying the amount of resin applied to the sample, varying the viscosity of the resin applied, altering the topography of the sample, altering the application of the fibers forming the sample, varying the sizes of the fibers, wrapping the sample, and varying the tightness of the sample;vacuuming the carbon fiber sample to remove air from the carbon fiber sample; andapplying pressure to the carbon fiber sample and curing the resin applied to the carbon fiber sample to form a solid carbon fiber composite.
