Abstract: To weld a filter made of a laser beam-transmittable fiber material to a case made of a laser beam-nontransmittable resin material by a laser beam the filter is first placed on the case; subsequently, the filter is pressurized by a jig to increase the fiber density of a welding portion; and then the welding portion is irradiated by the laser beam. In the step of increasing the fiber density, a periphery of the welding portion is pressurized by the jig to increase the fiber density of the filter in a larger area than the welding portion. Accordingly, the laser beam transmitting through the filter melts a part of the case, and the melted resin material permeates through gaps between the fibers constituting the filter, thereby welding the welding portion to the case.

Abstract: A polyethylene composite is manufactured by passing an inner core of fabric mesh sandwiched between two sheets of polyethylene material through a conventional set of high-pressure rollers at room temperature. The pressure exerted by the rollers on the polyethylene material causes its fluidification, so that each polyethylene layer permeates through the open mesh of the core material, bonds to the other layer and incorporates the core fibers to form a laminate composite. The thickness of the polyethylene sheets in relation to the gap and speed of the rollers has to be judiciously selected so that the pressure applied to the material is sufficient to fluidize the polyethylene at ambient temperature. Because no heat is applied to the system, the laminate composite is rapidly cooled as it passes through the rollers and requires no additional forming or processing.
