Patent granted for vehicle interior and exterior member
A recently granted patent (Publication Number: US11945147B2) discloses a vehicle interior and exterior member comprising a fiber molded body with a synthetic resin member affixed to its surface. The fiber molded body is formed by molding a fiber laminated body into a three-dimensional shape, with the synthetic resin member containing a foaming agent and gas bubbles. The patent also details a method for manufacturing this vehicle member, involving steps such as heating the fiber laminated body, press molding it into a fiber molded body, and injecting molten synthetic resin to create gas bubbles within the synthetic resin member. The method also includes cooling the molten synthetic resin and ensuring a portion seeps into the first fiber layer for fixation.
Furthermore, the patent claims specify the distribution and concentration of gas bubbles within the synthetic resin member, emphasizing their size and location relative to the first fiber layer. The method of manufacturing involves specific cooling techniques to control the formation of gas bubbles and ensure proper adhesion between the fiber molded body and the synthetic resin member. The patent also details the composition of the press mold used in the manufacturing process, highlighting the materials and configurations necessary for achieving the desired three-dimensional face shape of the final product. Overall, the patent provides a comprehensive guide for creating a vehicle interior and exterior member with a unique fiber molded body and synthetic resin member construction.
