摘要： In a method producing a molded article of a composite resin containing base resin and fibers, the composite resin containing a fibrous filler in the base resin and the fibrous filler including natural fibers with a fibrillated part on each end of the fibrous filler in a fiber length direction, the base resin and the fibrous filler are charged into a melt-kneading device. The base resin is melted and the molten base resin and the fibrous filler are kneaded in the melt-kneading device, thereby fibrillating only the ends of the fibrous filler. The obtained composite resin is discharged from the melt-kneading device and formed into a pellet shape, with the molded article of the composite resin produced by molding the pellets.

摘要： A method of forming a fiber-reinforced molding compound. The method includes establishing a melt stream of a source material including a first polymeric material having a first melt temperature in an extruder and dosing a composite material into the melt stream. The composite material includes pre-impregnated reinforcing fibers comprising reinforcing filaments and a second polymeric material having a second melt temperature greater than the first melt temperature. The composite material has at least 30% of the reinforcing filaments protected by the polymeric material such that the polymeric material surrounds each filament completely forming a barrier between it and an adjacent filament in the at least 30% of the filaments. The temperature of the melt stream at dosing is below the second melt temperature. The method includes forming a molding compound from the source and composite materials. The method includes dispensing the molding compound to produce a part.
