Description

technical field [0001] The invention relates to the field of composite materials, in particular to a low-temperature-resistant and impact-resistant automobile bumper material. Background technique [0002] Both the front and rear ends of the car are equipped with bumpers, which have the functions of safety protection, vehicle decoration and improvement of the aerodynamic characteristics of the vehicle. From the safety point of view, when the car has a low-speed collision accident, it can play a buffer role to protect the front and rear car bodies; it can play a certain role in protecting pedestrians in the event of an accident with pedestrians. [0003] The existing car bumpers on the market are more and more made of plastic materials, which are light, low-cost, and recyclable, but their defects are also prominent, such as poor low temperature resistance, poor energy absorption, and low impact resistance, which cannot meet the needs of the industry. Market requirements for ...
