Abstract

The popularity of additive manufacturing has been growing over the last few decades. Additive manufactured composites have a wide range of applications in engineering sectors specifically in aerospace structures. In addition to mechanical loads, they are subjected to thermal loads caused by aerodynamic heating. Temperature increases cause changes in material properties, which complicates thermal stress analysis. The thermal loading was simulated with specific boundary conditions similar to the experiments where the sample was placed inside the oven chamber. While for the mechanical (tensile) testing loading, the sample’s geometry was created with gripping lines to be in accordance with ASTM D3039 standards for tensile tests used in experimental work and surface traction for the applied load. The highest modulus and strength were achieved from the intact sample while the lowest mechanical modulus and strength were obtained in the sample with heat treatment at prolonged temperature of 145^◦C. At high temperatures, matrices soften affecting matrix-dominated properties such as transverse and in-plane shear stiffness and strength. A good correlation between the predictive models and experimental results is obtained.
