Modeling short fiber reinforced polymer matrix composite materials using material designer

Abstract In the present era, the importance of simulations pertaining to production is increasing in terms of cost, human resources, and time. As the majority of existing studies on polymer matrix composites are experimental, the development of a modeling approach for these materials will address a significant gap in the existing literature. In order to achieve this objective, the present study investigates the factors influencing the modeling of carbon fiber‐reinforced PPS composites produced by the injection molding method with the Ansys Material Designer tool. Composites containing 10% CF by weight were subjected to a tensile test subsequent to production. Subsequently, the tensile strength, elastic modulus, and tensile strain values obtained were then compared with the values were compared with those obtained from the modeled RVEs, with an examination of the various parameters in the Material Designer tool. The requisite parameter values for the optimal model, exhibiting the closest approximation to the experimental results, were derived from the modeled RVEs. The findings of the study indicated that the mean strength of the samples produced was measured at 143.73 MPa. However, when the optimum parameter conditions were met, this value was obtained at 141.48 MPa, with an error of 1.56% in the RVE model. However, this error increased to 18.58% in the elasticity modulus. Highlights The mesh was found to have no significant impact on the outcomes. The number of additives in the RVE had a direct effect on the results. Changes in the fiber distribution demonstrated comparable outcomes. The most crucial parameter for accurately modeling is the RVE size.
