Experimental data for cooling rate-dependent properties of Polyphenylene Sulfide (PPS) and Carbon Fiber Reinforced PPS (CF/PPS)

Abstract

In this study, the cooling rate-dependent properties of polyphenylene sulfide (PPS) and carbon fiber reinforced PPS (CF/PPS) manufactured at different cooling rates (1, 5, and 10 °C/min) are presented. The cooling rate-dependent densities of neat PPS and CF/PPS were determined based on the Archimedes' principle. The coefficients of thermal expansion (CTEs) were determined using a thermomechanical analyzer. The stress–strain curves of neat PPS manufactured at different cooling rates under tensile, compressive, and shear loading were obtained using a universal tester. In addition, the R curves of CF/PPS and the corresponding load–displacement curves are presented under mode I and mode II loading. The experimental data provide useful information for the development of numerical models that depend on both cooling rates and stress triaxiality. In addition, the data can be directly utilized to evaluate the properties and quality of carbon fiber reinforced thermoplastic components in the aerospace, automobile, energy, and civil engineering industries. Detailed experimental results have been presented in a previous study [1].
