Cracks Behavior Analysis of Jute Yarns Fiber Reinforced With Polyester Resin

Abstract

Jute yarns is one of the fibers that It can be supplied at a low price which can be used in a wide range of Applications of composite materials in industry where it works as a composite material with polyester. It is widely and practically used in construction And cars and aviation. In this paper, the composite material was prepared using polyester resins with different weight ratios of jute yarn at 5,15 and 25%. Manufactured by hand. And after obtaining the composite material with different weight ratios, mechanical tests were used to analyze and study the fracture surface through tensile testing and impact testing. The fracture surface was analyzed using SEM images for all weight ratios. Analysis of the images found that tensile fracture occurs easily. However, in impact fracture, the fiber test is well connected between the substrate and the fibers.
