Thermo-Mechanical Properties of Unsaturated Polyester Reinforced with Coconut and Snail Shells
Abstract: AbstractParticulate-filled polymer composites are becoming quite attractive because of their low cost and wide applications. In this study, the effects of coconut shell (CS) and snail shell (SS) volume fractions (5–50 vol. %) on the thermal and mechanical properties of unsaturated polyester resin (UPR) composite are investigated. The results show that tensile strength, elongation at break, flexural strength, and hardness of the composite increase as filler concentration increases. However, impact …
