Abstract

Mode I fracture behaviour of jute/glass fibre hybrid composite was investigated based on experimental and finite element analysis. Compact tension test was performed to find out the mode I fracture toughness. Fracture toughness was determined for five specimens each with different volume fractions of jute and glass fibre. The results indicated that 100% glass fibre composite gave maximum fracture toughness. Whereas composites with 75% glass & 25% jute fibre and 50% glass and 50% jute fibre also gave nearest values with that of pure glass fibre composite. A similar fracture test was simulated using the finite element analysis software ANSYS and critical stress intensity factor was calculated. The finite element analysis results are found to be close with the experimental results.

Keywords
