This paper is aimed at investigating the influence of temperature on mechanical properties and behavior of carbon fiber fabric reinforced polyphenylenesulfide (PPS) laminates subjected to different loadings: tensile, open hole tensile, in-plane shear, compressive, flexural, interlaminar shear, single-bolt double lap joint, and single-bolt single lap joint tests. The resulting experimental database is of the utmost importance for generating design allowables for structures integrating such thermoplastic-based composites. Depending on the test and the laminate's staking sequence, a temperature increase higher than the glass transition temperature (Tg = 98 degrees C) of fiber fabric reinforced PPS laminates softens the matrix behavior and significantly degrades the quality of the adhesion at the fiber/matrix interface, resulting in reduced mechanical properties (in-plane shear, compressive, flexural and interlaminar shear). However, it does not seem to be detrimental for the tensile and the double lap joint's properties in quasi-isotropic laminates. In angle-ply laminates, the ductile behavior of the PPS matrix is exacerbated at high temperature resulting in larger plastic deformations and a lesser hole sensitivity of this material.
