Effect of Fiber Orientation on Tensile Property of Basalt Reinforced Epoxy Composite

Abstract

Because of higher strength/stiffness, lower density and good chemical stability, basalt fiber-reinforced polymeric composites (BFRPs) have found many applications in various areas like aircraft, automotive, ship and packing industry. Purpose of study is to find out the fiber orientation’s effect for tensile property of BFRPs, produced by Temperature-Controlled Vacuum Resin Infusion Transfer (VARTIM) method. Standard tensile testing samples are prepared. Tensile tests are conducted at various fiber directions such as 0o, 45o, 0/90o, respectively, and a comparison is made among these composites. The results indicated that fiber arrangement affected the tensile behavior, especially for angle-ply samples. There are some differences occurred between longitudinal direction and orthogonal direction of tensile strengths around 460 MPa and 480 MPa, respectively. In 45o direction, tensile strength was around 82 MPa average but strain reached to 1.1%. In addition, analysis of variance results showed that orientation effects were statistically significant for 5%. Fisher’s Least Significant Difference Tests also confirmed that significant differences occurred among A, B and C factors.
