摘要:
Systems (300) for and methods of forming structural components from a source, such as one or more rolls (302), of a fibrous material (e.g., fabric) are disclosed. The fibrous material (304) is made up of multiple layers (308, 310, 312), with at least one pair of adjacent layers having different lengths.
摘要:
A load unit (700) of material for forming a structural component made from layers of a fiber reinforced material, the load unit (700) comprising a pallet (704) and a single layer of rolls of fiber reinforced material (702).
摘要:
A continuous fabric for use in forming a repair liner for reinforcing a pipe. The fabric includes a top layer and one or more bottom layers. The width of the top layer is less than the width of the continuous fabric and the density of the top layer is less than the density of at least one of the at least one or more bottom layers. The top layer may serve as a guide for winding the fabric in an overlapping pattern about a mandrel so that the essentially only the top layer is visible in the fabric winding.
摘要:
A hybrid sheet molding compound material is provided that includes at least one hybrid assembled roving comprising a plurality of reinforcement fiber strands (12) and a plurality of carbon fibers (14) comingled with the reinforcement fibers (12). The carbon fibers (14) are coated with a compatibilizer. The hybrid sheet molding compound material further includes a polymer resin material.
