Comparative study on the impact transition behaviour of PPS reinforced with 40%Vf glass

Composite materials, in most cases polymers reinforced with fibers, are these days utilized in numerous applications such as aerospace applications in which lightweight, high strength, high specific modulus and low temperature resistance are critical issues. As these materials have possible applications in different designing areas, a lot of work has been put into enhancing their performance. This study's aim was to study the impact transition behavior of PPS and its composite under different ranges of temperatures by investigating their thermal, mechanical and structural characteristics. PPS and its composite reinforced with 40% vf (volume fraction) glass fibers are employed in this study. The impact transition behavior of PPS and 40%Vf glass fibers composite were investigated by analyzing the mechanical properties: impact, tensile, bending and, hardness at the following temperature ranges: 23°C, -26°C, and -78°C. A particular refrigerator and dry ice were used to achieve the extremely low temperatures (-26 C and -78 C, respectively). The results showed that the addition of 40% glass fibers improved the impact transition behavior of 40%GF PPS composite with temperature decreasing. Which with decreasing in temperature from 23˚C to -78˚C, the impact strength of PPS decreased by fifty five percent while it increased by twenty three percent for
