Researchers at the Polymer Processing Research Laboratory of East China University of Science and Technology recently used composite modified PP as a compatibilizer and used a melt impregnation method to prepare a glass fiber mat reinforced PP thermoplastic composite sheet. By adding the composite modified PP, the compatibility between the matrix PP and the reinforcing fibers is improved, the tensile strength of the composite sheet is increased by 29%, the tensile modulus is increased by 23%, the bending strength is increased by 42%, and the flexural modulus is improved. Increase by 25%. This shows that the composite modified PP can be completely used as a compatibilizer, and the effect is remarkable.
