“…Short fiber–rubber composite (SFRC) is a type of polymer material with high performance, which has the rigidity of short fibers and the high elasticity of rubber, and gives its products a series of excellent properties such as high modulus, high hardness, tear resistance, puncture resistance, cutting resistance, low-pressure shrinkage deformation, load fatigue resistance, low heat generation, swelling resistance and creep resistance [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 ]. Stephan Günzel [ 2 ] et al found that short glass fiber-reinforced polyamides are increasingly used in automotive applications.…”
