Abstract: An apparatus for manufacturing stiffness-taper tubing includes a die having an extrusion hole, a die holder for holding the die, and a mandrel mounted inside the die holder and that fits in the extrusion hole. The apparatus forms stiffness-taper tubing by switching between and supplying resins having different stiffnesses over the mandrel from a plurality of resin-supply ports formed in the die holder such that the stiffness gradually changes in the lengthwise direction. A mandrel insertion hole connecting to the extrusion hole is formed in the die holder and the mandrel is mounted in this mandrel insertion hole. The plurality of resin-supply ports open to a cylindrical space formed between the inner surface of the mandrel insertion hole and the outer surface of the mandrel at a position separated from the extrusion hole in the die, and the plurality of resins flow together in this space.

Abstract: A method of making polymeric particulates wherein polymeric scrap material, virgin polymeric material and mixtures thereof are supplied to intermeshing extruder screws which are rotated to transport the polymeric material along their length and subject the polymeric material to solid state shear pulverization and in-situ polymer compatibilization, if two or more incompatible polymers are present. Uniform pulverized particulates are produced without addition of a compatibilizing agent. The pulverized particulates are directly melt processable (as powder feedstock) and surprisingly yield a substantially homogeneous light color product. The pulverized particulates also can be more intimately mixed than mixtures which are provided by only melt mixing, and can be melt processed without a significant delay in achieving phase inversion. The pulverized particulates also provide a stable microstructure.

Abstract: The invention is to perform operations from sealing of a honeycomb core with a thermosetting sealing material having an adhesive property to its hardening in one step, prevent a resin from flowing into cells of the honeycomb core during resin impregnating operation, and thereby mold low-cost honeycomb sandwich components by using RTM technique which is adopted in molding solid materials, for instance. Dry fabric sheets are stacked on both sides of a honeycomb core with thermosetting sealing members having an adhesive property placed in between, and the sealing members and the dry fabric sheets are heated at the curing temperature of the sealing members to cause initial hardening of the sealing members and to dry the dry fabric sheets. Then, the dry fabric sheets are impregnated with a thermosetting resin and the resin impregnated into the dry fabric sheets is hardened by hot-pressing an entire assembly thus prepared under specific conditions.

Abstract: The present invention is a continuous in-line compounding and extrusion system that does not require pre-dried wood flour or pelletized feed stock of cellulosic/polymer composite materials in order to produce net shapes from cellulosic/polymer composite materials. A preferred embodiment of the present invention utilizes automated loss-in-weight feeders to dispense wood flour and all of the other cellulosic/polymer composite materials into a compounder. The compounder blends the cellulosic/polymer composite materials into a composite melt. The composite melt is continuously devolitalized as it travels through the compounder, a transition chute, and a finish extruder. The composite melt is then forced through a profile die which is fitted to the finish extruder in order to achieve a net shape.
