| description | A method and apparatus for producing a reinforced composite prepreg material comprising the steps of aligning discontinuous fibers by use of a strong electric field while simultaneously inserting the fibers through a mesh screen and into a ply or plies of fiber reinforced polymer matrix composite in an uncured state in a direction normal to the surface of the composite material. After the fibers are attached in the ply of fiber reinforced polymer matrix composite, the aligned fibers are forced through the composite material by applying a gentle pressure to the top of the conductive fibers while simultaneously being guided by the mesh screen. After the insertion process has been completed, the mesh screen is lifted vertically away from the composite material and any unaligned fibers are simultaneously removed. The newly formed reinforced prepreg composite films are then stacked on top of each other and pressurized and cured in an autoclave or press to produce an improved composite laminate. |
