Latest Patents
Choul Won So's latest patents include a polyolefin resin, a preparation method therefor, and a vehicle rear bumper beam using the same. The polyolefin resin is characterized by being composed of a thermoplastic resin composite that includes a polymer base made of a polypropylene homopolymer, which has a molecular weight distribution of 2 to 10, along with a colorant. Additionally, a fiber reinforcing material is impregnated into the polymer base, with a length of 5 to 20 mm, where 10 to 50 wt % of the fiber reinforcing material is included with respect to the polyolefin resin. The method for preparing this resin involves forming a thermoplastic resin composite by impregnating a molten mixture of the polypropylene homopolymer and a colorant with the fiber reinforcing material. Furthermore, his invention of a bumper system for vehicles includes a bumper beam with fastening holes, a crash box, and a bracket designed to prevent the crash box from separating, ensuring compliance with low-speed crash regulations and RCAR
