  • Publication number: 20230158784
    Abstract: A vehicle component unit including a reinforcing open area core layer, a high gloss surface layer, and an encapsulating plastic layer. The reinforcing open area core layer has a first side and an oppositely opposed second side and a first end and an oppositely opposed second end each extending between the first side and the second side. The high gloss surface layer is positioned on the first side of the reinforcing open area core layer. The encapsulating plastic layer has a first end and a second end and is positioned on the second side of the reinforcing open are core layer. The first end and the second end of the encapsulating plastic layer are embedded into the high gloss surface layer with an embedded length L, such that the encapsulating plastic layer covers the first end and the second end of the reinforcing open area core layer.

  • Patent number: 10293770
    Abstract: Provided is a load-carrying or non-load carrying structural component for a vehicle having improved impact resistance, such as a gas tank protection shield, an underbody shield, a structural panel, an interior floor, a floor pan, a roof, an exterior surface, a storage area, a glove box, a console box, a trunk, a trunk floor, a truck bed, and combinations thereof. The component has a support structure with ridges, each spaced apart from one another at predetermined intervals, to form a corrugated surface capable of load-carrying. The ridges are longitudinally extending, raised ridges. The corrugated designs provide support structures that are impact resistant.

  • Patent number: 10006677
    Abstract: The present invention provides a method for manufacturing a shaped product constituted by a fiber-reinforced composite material including reinforcing fibers and a thermoplastic resin. The shaped product maintains isotropy of the fibers to the end thereof even if press-molded under conditions in which charge ratio of a prepreg to a die is low. Specifically, the method includes using a specific prepreg obtained by impregnating the reinforcing fibers with thermoplastic resin, and molding-processing the prepreg under specific conditions.
