Steel - -

Carbon Fibre 138 6

Glass Fibre 14 -44

• 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

6. Conclusion

8. Recommendation

7. Conclusion and Recommendations

Area Description

Material Data• Experimental value needed• Non-linear gives better prediction

Load Cases • Test for multiple directions

Joining Method• Fastener checks• Attachment with other components

Environment• Earthquake• Fire
