Abstract

Mechanical properties of a structure and materials is essential in designing a product to know the strength of the material as well as the structure. The purpose of this research is to study and analyze the mechanical properties of fiber reinforced plastic pipe. The research is collaborated with Pacific Advance Composites Sdn. Bhd. to know the mechanical strength of their pipe design and the 3 inch in inner diameter welded and plain pipe specimen was prepared by that company. In this study, tensile and bending test was done in order to know the tensile and bending strength of the FRP pipe. In conjunction to that, a jig has been designed according to ASTM D2105 to accommodate the pipe specimen with the Universal Testing Machine for tensile testing. A critical component of the jig has been analyzed with finite element analysis software in order to know the safety factor of the jig while targeted force is applied. The tensile test is conducted in accordance to ASTM D2105 which recommended by ISO 14692-2:2002 while bending test is conducted accordance to ASTM D790. From the tensile testing, it is found that the specimen does not fail despite the maximum force applied was 33.535 kN. Also, it is found that the failure is happening at the stress concentration area from the modification done to the specimen. Next, the bending test was done and found that the failure is happening due to the brittleness and shearing effect on the specimen. From both of the test, it is suggested that the jig need to be modify to have higher gripping pressure for the test and for bending test, the span length of the specimen need to be increase in order to give higher bending moment.
