Evaluations of Epoxy Polymer Composites Reinforced with S-Glass Fibers and NaOH Treated Areca Nut Fibers for Mechanical Studies
摘要
In the current market, bio fibers are seeing a significant demand due to the fact that they are environmentally friendly, have a high availability, and are available at a very low cost. The purpose of this study was to investigate the use of areca fibers and s-glass fibers as reinforcement with the purpose of improving mechanical applications. In comparison to untreated fibers, which is having 15.5 MPa tensile strength, 10 wt.% areca fiber and 10 wt.% glass fiber mixture had 23.83 MPa tensile strength. A maximum of 41.4 Mpa tensile strength was obtained when the total weight percentage was up to 40 and the alkali treatment was applied. The tensile modulus increased as the ratio of hybrid fibres containing areca and glass fibres was increased to 50% of the total weight. Flexural strength increased as a result of alkali treatment when hybrid fibres were added at a weight percentage of 20–50 percent. The alkali-treated and untreated fibre combinations were found to have impact characteristics of 3.02–4.56 kJ/m2 and 2.54–3.47 kJ/m2, respectively. A pressure-absorbing zone was created as a result of the fibers interfacial adhesion to the matrix, which had a positive effect under higher loads. A protective film was developed as a result of the fibres and matrix bonding to each other more effectively. This layer will shield the specimen from experiencing an elevated level of wear caused by the matrix. The rate of friction has an exponential relationship with increasing quantity of hybrid fiber and applied pressure load. A higher COF is the result of increasing the percentage of fibres in the hybrid fibre combination. This combination possesses a high level of hardness. These hybrid composites are suitable for automotive interiors, building panels, consumer products, and marine components due to their high strength, durability, and eco-friendliness.
