  • Publication number: 20190275705
    Abstract: A method of forming fiber-reinforced composites. The method includes stabilizing two or more carbon fibers tows together (a) with a stabilizing resin and (b) in-line with a commercial carbon fiber production process to form a semi-finished tape; and impregnating the semi-finished tape with a matrix resin in a process offline of the carbon fiber production process to form a prepreg.

  • Publication number: 20190248044
    Abstract: 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.

  • Publication number: 20190022896
    Abstract: A method of forming a fiber-reinforced molding compound. The method includes pre-impregnating carbon reinforcing fibers with a polymeric material to form one or more pre-impregnated continuous strands having at least 30% of the fibers protected by the polymeric material. The method further includes storing the one or more pre-impregnated continuous strands in bulk. The method also includes introducing the one or more pre-impregnated continuous strands into an extruder, forming a molding compound from the one or more pre-impregnated continuous strands, dispensing the molding compound from the extruder, and using the molding compound to produce a part.

  • Patent number: 10024036
    Abstract: Wear members for wear assemblies include a lock configured to secure the wear member to a base, where the lock has two engagement positions, namely: (a) a first position that secures the lock to the wear member, and (b) a second position that secures the wear member to the base. The locks are further configured to be unlatched and removed from the wear member in two phases, a first retraction of the latching mechanism, followed by a rotation of the lock itself with removal from the wear member.

  • Patent number: 10011049
    Abstract: 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 and dosing a composite material into the melt stream. The composite material includes pre-impregnated reinforcing fibers and a second polymeric material. The method further includes forming a molding compound from the source and composite materials and dispensing the molding compound from the extruder. The first and second polymeric materials are different than each other to introduce a functionality into the molding compound that is not present in the second polymeric material. The method further includes using the molding compound to produce a part.

  • Patent number: 9677596
    Abstract: A method for forming an elevated surface feature for compression molded assemblies includes the placement of an afore-mentioned insert onto an actuated fixture pin with the pin initially in a retracted position. An upper portion of a mold configured with said retracted actuated fixture pin over a preform of pre-preg plies placed on the bottom portion of the mold is then closed. The fixture pin is actuated towards the pre-preg plies when a flowable material fills a molding cavity in the upper portion of the mold. The cavity is configured to form the elevated surface feature with the advancing action of the insert packs out the surface feature under the pressure of the pin to eliminate porosity in the elevated surface feature in the molding cavity.

  • Publication number: 20160375649
    Abstract: A process for forming a composite sandwich panel assembly is provided that includes positioning a top sheet and a bottom sheet on opposing sides of an open pore matrix core. The top sheet, bottom sheet, and core are exposed to a heat source with the application of a clamping pressure to the top and the bottom sheet. The heat source is then removed and the clamping pressure maintained for a period of time. The clamping pressure is removed when the top sheet, bottom sheet, and core have cooled and fused together. An assembly formed by such a process is also provided.
