Effect of Reinforced Glass Fibre on the Mechanical Properties of Polyamide

Abstract

The aim of this study is to enhance the tensile and flexural strength of polyamide (nylon 6, 6) by incorporation of glass fibre. Nylon has high elasticity, strength, toughness and maintain mechanical properties at elevated temperatures. The method employed for enhancement of properties is by the reinforcement of glass fibre. Glass fibre is the most extensively used reinforcement material. It is a lightweight, extremely solid, durable, low cost material that moderafly stiff. The composition of glass fibre was kept at 0 wt.%, 30 wt.% and 50 wt.% in nylon 6,6 blend. Initially, samples were manufactured by injection molding of nylon 6,6 and glass fibre. The pressure and velocity profiles at 0 wt.%, 30 wt.% and 50 wt.% reinforced nylon 6,6 are also compared. The samples thus formed were checked for shrinkage. The samples were tested for their tensile and flexural properties. The mechanical properties of polyamide (nylon 6,6) significantly improves by increasing glass fibre reinforcement.
