Abstract
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, inโplane shear, compressive, flexural, interlaminar shear, singleโbolt double lap joint, and singleโbolt single lap joint tests. The resulting experimental database is of the utmost importance for generating design allowables for structures integrating such thermoplasticโbased composites. Depending on the test and the laminate's staking sequence, a temperature increase higher than the glass transition temperature (T~g~ = 98ยฐC 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 (inโplane 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 quasiโisotropic laminates. In angleโply 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. ยฉ 2011 Wiley Periodicals, Inc.
