What are the main advantages of fiber-reinforced composites?
Low strength-to-weight ratio, susceptibility to corrosion, and limited design flexibility
High strength-to-weight ratio, corrosion resistance, and design flexibility
Explain the difference between continuous and discontinuous fiber-reinforced composites.
Discontinuous fiber-reinforced composites have fibers that run continuously through the material, providing high strength and stiffness.
Continuous fiber-reinforced composites have fibers that are randomly oriented, providing improved impact resistance and toughness.
Continuous fiber-reinforced composites have fibers that run continuously through the material, providing high strength and stiffness. Discontinuous fiber-reinforced composites have fibers that are randomly oriented or chopped, providing improved impact resistance and toughness.
Continuous fiber-reinforced composites have no fibers, making them weaker than discontinuous fiber-reinforced composites.
How does the orientation of fibers affect the properties of fiber-reinforced composites?
The orientation of fibers has no effect on the properties of fiber-reinforced composites.
The orientation of fibers only affects the color of fiber-reinforced composites.
The orientation of fibers increases the electrical conductivity of fiber-reinforced composites.
The orientation of fibers affects the mechanical properties of fiber-reinforced composites.
What are the different types of resin matrix composites?
Metallic, Ceramic, Glass
Fiberglass, Carbon fiber, Kevlar

Explain the process of curing in resin matrix composites.
Curing is the process of adding a layer of paint to the surface of the composite material.
Curing in resin matrix composites is achieved by exposing the material to direct sunlight for several hours.
The process of curing involves the application of heat and pressure to initiate and complete the polymerization reaction of the resin.
The process of curing involves soaking the composite material in water for a specific period of time.
