Finite Element Prediction of Mechanical Properties of Composite Materials at Different Temperatures

A numerical model has been developed to predict the mechanical properties of GRP, CFRP and KRP composites under three key temperatures, namely, -46°C, +20°C +70°C. This model has been used to calculate the hoop modulus of these materials in the form of 3 cover tubular specimen with three different winding angles, ±25°, ±55°, and ±75°, i.e. angle between fibers and tube axis. This model is also capable of predicting other mechanical properties over a wider temperature range and winding angles. Comparison of the equivalent hoop modulus from this model with experimental results carried out in a separate research showed good agreement.
