The method for calculating the elastic parameters of continuous glass fiber/PE reinforced composite

To study the elastic properties of continuous glass fiber/PE reinforced composite belt, a model was established, and the foundamental assumption of their materials and structure was proposed. The elastic parameters of the composite belt were solved based on the theoretical formula method. The finite element model of the composite belt under the uniaxial tensile state was established. The displacement coupling of the glass fiber and PE was performed. The elastic modulus of the composite belt along the length direction of the fiber was calculated. The calculation results agree well with the theoretical results. The elastic moduli of the composite belt along both the length and bandwidth directions of glass fiber were obtained by tensile test. The elastic modulus of the composite belt along the bandwidth direction agree well with the theoretical results. The elastic modulus of the composite belt along the length direction is smaller than the theoretical and numerical solutions, because of the difference in the processing technique and the material state between the assumption conditions and the actual conditions, and the errors during the experimental testing process.
