Contrast Joints of Glass Fiber with Carbon Fiber-reinforced Low-density Polyethylene Composite Bonded by Microwave Irradiation

Abstract

This paper contrasts the loss tangent, durability of reinforcement and, lap shear strengths of 33% by weight random glass fiber-reinforced low-density polyethylene matrix composite [LDPE/GF (33%)] with 33% by weight random carbon fiber reinforced low-density polyethylene matrix composite [LDPE/CF (33%)] bonded using microwave irradiation. Fixed (2.45 GHz) and variable (2-18 GHz) frequency microwave (VFM) facilities are used to bond the two composites. With a given power level, the composites are exposed at various exposure times to microwave irradiation. The primer or coupling agent used for joining the glass fiber-reinforced composite is a 5-min two-part adhesive, Araldite. No filler was used in joining the carbon fiber-reinforced composite.
