L10 Summary - Coggle Diagram

- - - - repaired structure must be able to withstand the same load as the original structure
    - - stiffness of the material must be as same as the original material which can prevent excessive deflection and unnecessary load distribution
        
        less stiff -> fail easily
    - - should not create more weight
    - - should have smooth external surface to minimize drag
- - - - Top Skin Damage Only
        
        caused by low energy impacts
        
        only top skin removed
        Top Skin and Core Damage
        
        due to greater impact
        
        cause debonding
        
        core must be remove with the skin
        Damage Through the Laminate
        
        remove core and taper both side of skin
    - - damage should be cut/removed in circular or oval shape
        
        it there is sharp edges, there will be little debris, which makes repair more challenging and stress concentration areas created/increase
      - routing and grinding cn produce large amount of disintegrated fibers and dust which can enter our lungs -> use proper PPE (disposible clothing and respirator)
