  • Patent number: 11072093
    Abstract: A process for producing a carbon sheet molding compound (SMC). An SMC manufacturing line including at least one conveyor line for laying up SMC resins on a carrier film is provided. A chopped carbon fiber which is evenly distributed using dehumidified supply air and using a pressurized air venturi apparatus which is used to debundle and randomize the carbon fibers, onto the resin on the carrier film as the carrier film moves along the conveyor.

  • Publication number: 20210221074
    Abstract: A process for molding a hollow structure comprising the steps of: a. Forming a mandrel in a shape of a proposed cavity from a water-soluble substance capable of withstanding temperatures and pressures from a predetermined compression molding process; b. Positioning the mandrel in a suitable mold for forming an article which includes the mandrel within the article; and, c. Removing the mandrel by loosening and dissolving the mandrel with a water solution, thereby creating a cavity in the article.

  • Publication number: 20210213692
    Abstract: Co-molding of non-crimped fabric and sheet molding composition. The pre-preg of non-crimped fabric is dried to achieve suitable stiffness for molding. The pre-preg allows the pre-formed non-crimped fabric feature to retain its shape during molding. A plurality of thorns is provided in the molding tooling to further prevent movement of pre-preg during molding. The method of co-molding includes, drying of the pre-preg to achieve suitable stiffness for molding, pre-forming of the pre-preg, and incorporating a plurality of stand-off features or thorns in the molding tool to prevent movement of pre-preg during co-molding so that predetermined full coverage of non-crimped fabric is maintained in predetermined area(s) of the molded part and the continuous fibers of the non-crimped fabric are not distorted.

  • Publication number: 20200262480
    Abstract: A structural automotive sub frame component (10) that is formed from a sheet molding compound having carbon fibers. The three dimensional structure is formed of a resin fiber mixture having a resin material infused with carbon fibers having a length of about 12.5 mm (0.5 inches) dispersed throughout the structural automotive sub frame component (10) and an even manner such that there are no resin rich areas or knit lines present. The absence of knit lines provides a structural automotive sub frame component (10) that has a high degree of flex modulus, tensile strength properties well also providing a greater breaking load property due to the absence of knit lines.
