Abstract
Over the past two decades, there has been a remarkable surge in the utilization of composites, with fiber-reinforced polymer composites gaining significant traction owing to their commendable structural performance. Concurrently, extensive research has been conducted to assess the behaviour of composite materials, focusing on various parameters such as fiber type, lamination order, matrix type, and the inclusion of filler materials. In this study, we investigated the hygrothermal analysis and mechanical properties of flax (F)ramie (R) epoxy hybrid composites pretreated with NaOH filled mixed with nano SiO2, specifically exploring the effects of different weights of nano SiO2 mixed with epoxy hybrid composite. Three distinct weighing of nano particles with same sequence of FRFRF was choosen:0.5 %,1.5 %,2.5%. The composites were fabricated using vacuum assisted resin transfer molding techniques, adhering to ASTM standards for the evaluation of mechanical properties including tensile strength, flexural strength and interlaminar shear strength. The most favourable results were observed with 2.5 % Nano SiO2 composite, boasting a tensile strength of 28.06 MPa, interlaminar shear strength of 8.13 MPa and flexural strength at 84.6 MPa. Additionally, Hygrothermal analysis was conducted to investigate moisture absorption of the composite.
