The purpose of this research is to investigate the physical and mechanical characteristics of hybridized composites made from Ramie fibre, nano-silica, and epoxy. A hybrid composite containing 0, 2, 4, and 6% Silica by weight and four layers of the Ramie fibres was prepared using the hand layup procedure and then compression moulded. Mechanical qualities were determined by doing tests for hardness, flexural strength, tensile strength, and impact resistance. Hybridized composites with up to 4 wt.% silica and Ramie fibre have significantly better mechanical characteristics. According to the results of Rockwell Hardness testing, composites’ hardness (at the R4 level) has increased by up to 29% since the R0 level. At 4 wt.% Silica, the tensile strength is roughly twice that of neat laminates. The R4 now has a 50% greater impact strength than before. Up to 4wt.% Silica reinforcing, flexural characteristics are also improved. For the development of material qualities, wear tests were conducted on density, water absorption, and thickness swelling.

摘要

The purpose of this research is to investigate the physical and mechanical characteristics of hybridized composites made from Ramie fibre, nano-silica, and epoxy. A hybrid composite containing 0, 2, 4, and 6% Silica by weight and four layers of the Ramie fibres was prepared using the hand layup procedure and then compression moulded. Mechanical qualities were determined by doing tests for hardness, flexural strength, tensile strength, and impact resistance. Hybridized composites with up to 4 wt.% silica and Ramie fibre have significantly better mechanical characteristics. According to the results of Rockwell Hardness testing, composites’ hardness (at the R4 level) has increased by up to 29% since the R0 level. At 4 wt.% Silica, the tensile strength is roughly twice that of neat laminates. The R4 now has a 50% greater impact strength than before. Up to 4wt.% Silica reinforcing, flexural characteristics are also improved. For the development of material qualities, wear tests were conducted on density, water absorption, and thickness swelling.
