Abstract

Aim:The aim of present research work is to find the flexural strength of novel composites made of aluminum powder and woven Okra fiber. Materials and Methods: The okra fiber acts as a control group, whereas the aluminum powder acts as an experimental group in this study. There were two groups involved, each with a sample size of 20 and a total of 40 samples. The G power for the independent sample tests utilized in this investigation was set to 80 %. The okra fibers were treated with 5 % KOH solution. To accomplish the above mentioned objective the following parameters were chosen like (i) aluminum powder (μm), (ii) okra fiber mate (gsm), and (iii) KOH treatment hours (hours), each at three distinct levels. The L9 orthogonal array was chosen for the appropriate parameters, and the necessary composite materials were manufactured by hand lay-up procedures. Results: Based on the experimental trials, the flexural properties of the hybrid novel composites were considerably improved. The composite provides the highest value of flexural strength (46.69 MPa) upto 4 hours of KOH treatment and it provides the significance values of P = 0.041 (P<0.05). Conclusion: The research shows that the suggested levels of controlled process parameters for okra fiber and aluminum powder based hybrid novel composites are 15 μm of aluminum powder, 300 gsm of okra fiber and 4 hours of KOH treatment.
