Which term is used for the material that provides strength in a composite?

• A. Reinforcement
• B. Matrix
• C. Planned Obsolescence
• D. Repair

Answer: (A)

In composites, there are two parts: a strong reinforcing material and a surrounding binder. The reinforcement carries most of the load and gives the material its high strength and stiffness, while the matrix binds the reinforcement together and helps distribute the stress. So the term for the material that provides strength in a composite is reinforcement. The matrix, usually a resin, binds and protects the reinforcement. Planned obsolescence and repair aren’t related to what provides strength in a composite.
