• Significant improvement observed• Weight Saving• Approximately 70% weight loss over metal
• Deflection• Carbon fibre composite reduced beam deflection by 50%• Glass fibre composite deflects 200 times more than steel
• Factor of Safety• Carbon fibre composite 138 times stronger than steel• Glass fibre composite almost 40 times weaker than steel
