Abstract: The invention relates to an apparatus and method for fabricating FRP parts. More specifically, the invention relates to a method for forming FRP parts without the use of forms or molds. According to a preferred embodiment of the present invention, the method for fabricating an FRP part comprises the steps of: programming a readable definition of a part into a machine, wherein the machine moves an extrusion head mounted to the machine in a controlled pattern; and wherein the machine regulates the speed of extrusion from the extrusion head; feeding a fiber reinforcement to the extrusion head of the machine; impregnating the fiber reinforcement with a radiation-initiated resin; extruding the impregnated fiber reinforcement from an orifice in the extrusion head; and exposing the extruded fiber reinforcement to curing radiation.

Abstract: The present invention relates to loudspeaker cabinets composed of a moldable wood material and a method for making the same. In particular, the present invention relates to loudspeaker cabinets composed of a compression molded cellulose (CMC) material resulting in a cabinet for loudspeakers with improved acoustic and physical properties. In accordance with the present invention, a compression molded cellulose material, and a process for the mixing, extrusion, and compression molding of the compression molded cellulose material has been developed. Cabinet designs with rounded forms are made possible using the compression molded cellulose material and process. The characteristics of the compression molded cellulose material in combination with the unique shape of each cabinet is designed to enhance the fidelity of the sound produced by the loudspeaker mounted in the cabinet.
