Abstract
CFRP laminates are used by about 50% weight ratio in the body of the Boeing 787 jet plane. Many kind of impact damage, for example due to the collision of small stone, bird, tool dropping and hail, may be introduced in the airplane body during the long time use. The effect of impact damage due to dropping weight on the flexural strength of the fabricated CFRP laminates with copper mesh sheet, were investigated. The flexural strength decrease strongly, depending on the impact damage. Effect of the cure condition on the strength of CFRP with copper mesh sheet was recognized. The strength of CFRP with copper mesh sheet against impact damage was good compared to the result of CFRP.
