L10 Summary
Section 1: Damage
-
-
goal of repair
-
- 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
-
Structural repair manual
- use same material
- same orientation
- stacking sequence processing methods
substitution material must be same as original material
Section 2
Damage removal
-
Once damage have been identifies, can cut using sharp knife
- routing for cleaner cut and reduce splinter
- grinding to sand away material
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)
