Mechanical Properties of Automotive Instrument Panels with Semi-Rigid Foam

Abstract:

Semi-rigid polyurethane foam to soften the instrument panel has a lightweight, impact and energy absorption performance, while improving the texture of the surface of the instrument panel. This article was prepared by one-step car instrument panel with semi-rigid polyurethane foam, through the design of the four factors and three levels orthogonal test program, using Fourier infrared spectroscopy to characterize its structure, measuring its apparent density and hardness properties of transformation, the combination of research influence of the proportion of polyether foam system.
