Introduction to Composites
- What is a composite material and what characteristics make composites useful in engineering? In one line A composite is a multiphase material made by combining two or more chemically and physically different constituents, separated b... 1
- What is the matrix phase in a composite and what functions does it perform? In one line The matrix is the continuous phase of a composite that surrounds and binds the dispersed phase, transfers load to it, protects i... 1
- What is the dispersed (reinforcing) phase in a composite and what are its functions? In one line The dispersed phase is the discontinuous phase (fibres, particles, flakes) embedded in the matrix that mainly carries the load a... 1
- How are composites classified based on the type of reinforcement used? In one line Based on the reinforcement, composites are classified into particle-reinforced, fibre-reinforced and structural composites, each... 1
- How are composites classified by matrix as polymer, metal and ceramic matrix composites? In one line Based on the matrix material, composites are classified as polymer matrix composites (PMC), metal matrix composites (MMC) and ce... 1
- What are fibre-reinforced composites and why does fibre length and orientation matter? In one line Fibre-reinforced composites contain strong, stiff fibres embedded in a matrix; their strength depends heavily on fibre length, o... 1
- What are structural composites like laminates and sandwich panels, and why are they so stiff yet light? In one line Structural composites are made of layers or of face sheets and a core bonded together, and their properties depend on the geomet... 1
- Explain fiber reinforced composite and write its applications and limitations. Fibre-reinforced composites (FRC) are composites in which the dispersed phase is in the form of fibres, i.e. long, thin filaments with a hig... 1
- Define Matrix phase and dispersed phase of composites. A composite has two constituents: 1. Matrix phase – the continuous phase that surrounds and binds the other phase. It may be a polymer, meta... 1
- Write a short note on sandwich panel of structural composite write its applications. Sandwich panel (a structural composite) A sandwich panel has two thin, strong and stiff outer face sheets (skins) bonded to a thick, lightwe... 1
- Discuss applications of composites. Composites combine high strength and stiffness with low weight and good corrosion resistance. Their main applications are: Aerospace: CFRP a... 1
- Classify composites with the help of a diagram and an example of each class. COMPOSITES ______________________|______________________ | | | Particle-reinforced Fibre-reinforced Structural ____|____ ____|_______ ____|_... 1
- Define matrix and dispersed phase with its functions and examples. A composite has two constituents: 1. Matrix phase – the continuous phase that surrounds and binds the other phase. It may be a polymer, meta... 1
- Define Matrix phase and dispersed phase with example. A composite has two constituents: 1. Matrix phase – the continuous phase that surrounds and binds the other phase. It may be a polymer, meta... 1
- Explain Laminar and sandwich panel of structural composite. Structural composites are made of homogeneous and composite layers. Their properties depend on the constituent materials and on the geometri... 1
- Explain a) Fiber glass reinforced composite. b) Carbon fiber reinforced composite. a) Glass-fibre reinforced composite (GFRP / fibreglass) Constituents: continuous or chopped glass fibres (E-glass, S-glass), about 3–20 µm i... 1
