Experimental investigations on the tensile properties of notched and unnotched carbon woven-ply PPS laminates at different temperatures

The effect of temperature on the mechanical behavior of woven carbon fabric/polyethylene sulfide (CF/PPS) was investigated in this paper. Tensile tests were both conducted on notched and unnotched specimens at different temperatures (ambient, 95°C and 125°C), their strength and moduli were obtained and compared. The damage patterns of notched specimens were examined with the aid of optics. The results revealed that the strength of the two type...
