Characterization of Amino Silane Modified Ramie Fibre, OMMT Nanoclay-reinforced Epoxy Resin Composite

The importance of adding surface treated Ramie fibre and nanoclay in epoxy resin composites was investigated in this research. The key goal of this study was to demonstrate the significance of surface treatment on naturally occurring fibres and fillers as they are indented for use in high-performance composites. The surface of the Ramie fibre was treated using an amino silane whereas the nanoclay was organo-montmorillonite (OMMT). The composites were made using a hand layup process of 40 vol% Ramie fibre and 0.5, 1.0, 1.5, 2.0, and 2.5.% nanoclay reinforcement. The specimens are then tested for various mechanical properties such as tensile, flexural, impact, and hardness in accordance with ASTM standards in order to determine the composite’s strength. Wear and fatigue properties were also investigated to determine the outcome of surface-treated fibre and particle in a polymer matrix. The mechanical properties of the 40 vol% Ramie fibre and 1.5 vol% OMMT nanoclay are found to be better. Wear tests showed that a composite containing 40vol. % of fibre and 1.5vol.% of OMMT nanoclay produced high abrasion resistance. Similarly, fatigue life counts of composites containing 1.0vol. % nanoclay shows 44,218 cycles. Water absorption resistance is balanced because of silane-treated ramie fibre and OMMT nanoclay in epoxy composite. There is no vast decrement in hydrophobicity on compare with bare resin. The SEM images show exfoliation of OMMT nanoclay in the matrix as well as increased Ramie fibre adhesion to the matrix.
