Abstract

Evaluating the tensile strength of novel epoxy composite laminates with and without stainless steel wire mesh reinforcing. Composite laminate without stain less reinforcement is made using five plys of bidirectional composite laminate fabric (kenaf-kenaf-kenaf-kenaf-kenaf (K-K-K-K-K), and composite laminate with reinforcement is made using bidirectional fiber fabric and stainless steel wire mesh stacked in the sequence K-S-K-S-K (kenaf-stainless steel-kenaf-stainless steel-kenaf). This research is aimed at achieving better tensile strength with the addition of stainless steel wire mesh reinforcement. The experimental and control groups were each given a sample size of 20. The tensile testing is done according to the ASTM D3039 standard. To analyze the tensile strength, T-independent tests were done using the SPSS statistical software tool. According to the experimental data, group 1, a novel kenaf fiber reinforced stainless steel wire mesh epoxy composite laminate, had an average of 20.8519 MPa, while group 2, a novel kenaf fiber-reinforced composite laminate, had an average of 16.2721 MPa. The number of samples was decided with a power of 80%. The results of the studies were assessed using the T-test, and it was found that the significance value of p < 0.001 was attained, which is less than (p < 0.05) indicating that there is a statistically significant difference between the two samples. The mean tensile strength of the samples in the experimental and control groups is 20.8519 MPa and 16.2721 MPa, respectively. The resulting tensile strength of the samples of the experimental group is on average 44% higher than that of the control group.
