Effect of Temperature on the Impact Performance of Short Fiber Reinforced Composites

Abstract:

In order to test the impact performance of short glass fiber reinforced composite materials in different temperature, on the basis of molding process, the specimens of polypropylene modified resin based glass fiber reinforced composites were made, the impact performance of the materials with the different temperature of -35°C, 23°C and 80°C were tested. Results show that the maximum load of specimen can bear is gradually increased with the temperature increase, and the maximum impact load of specimen is 0.8722kN at -35°C, while the maximum impact load which is improved 38% is 1.2024kN at 80°C. Also the energy absorbed by composite materials increase with the temperature increase. Results also show that the composite materials manifest as plastic fracture in high temperatures and brittle fracture in low temperatures.
