Thermoplastic composites Flashcards
1
Q
What advantages do thermoplastic composites have over thermoset composites?
A
Fracture toughness Environmental resistance Potentially simplified joining and repair Faster fabrication time Potential for lower cost fabrication
2
Q
Undesirable results that occur while forming thermoplastic composites
A
Fiber bridging
Fiber breakage
Wrinkling
Imperfect consolidation
3
Q
Deformation mechanisms
A
Resin percolation
Transverse flow
Interlaminar slip
Intraply shear
4
Q
Matched die molding
A
Displacements and curvatures must be limited to avoid damage to composite
5
Q
Rubber forming
A
One die replaced with silicone rubber, either flat or shaped
6
Q
Diaphragm forming
A
Thermoplastic sheet placed between two flexible diaphragms- apply a more uniformly distributed force
