Composite Materials
5 self-contained study topics — notes, diagrams, formulas, and worked examples for exams and GATE.
Topics
- Composite ConstituentsComposite constituent relations estimate stiffness and density from fibre-matrix volume fractions.
- Laminate TheoryClassical laminate theory builds global ABD matrices from ply stiffness and stacking sequence.
- Failure Criteria for CompositesComposite failure criteria compare multiaxial ply stresses against directional strength allowables.
- Manufacturing of Composite PartsComposite manufacturing controls fibre alignment, void content, and cure cycle to achieve design allowables.
- NDT for Composite StructuresNDT for composites detects delamination, disbond, and porosity without damaging costly primary structures.
