Correlation between Process Parameters with Flexural Properties of Hybrid Glass/Jute Fibre Reinforced Epoxy Composite Fabricated via Vacuum Infusion Technique

摘要

Flexural properties of hybrid glass/jute fibre reinforced epoxy composites were optimised by response surface methodology. The processing parameters of vacuum infusion technique such as supply pressure, soaking time and use of flow media were investigated. The flexural properties of the resulting composites were evaluated using three-point bending test in accordance with the ASTM D790-03 standard. The flexural strength of ～195 MPa and elastic modulus of ～13412 MPa were achieved at optimum parameter of 100 kPa pressure, 120 minutes soaking time with the utilization of flow media during vacuum infusion process.
