Influence of void content on the mechanical properties of carbon/PPS laminates

Abstract : Void content of several carbon fiber/PPS laminates was investigated to assess the impact of porosity level on mechanical properties of thermoplastic materials. Specimens with a [0°/90°] 6 stacking sequence were produced by various autoclave and oven consolidation cycles in order to obtain a void content in the range of 2.0% to 6.0%. Mechanical properties (tensile strength and modulus; flexural strength and modulus, interlaminar shear strength) were measured and results were related to void content. Results show that contrary to tensile strength, flexural and interlaminar shear strength are particulary sensitive to void content. C/PPS tensile and flexural moduli are also weekly affected by void content.
