Sheet Metal Trade And SMWIA 2nd Year Practice Test

FRP is made from what material arrangement?

Alternating layers of fiberglass cloth and resin over a mold. Sheets of aluminum with epoxy coating Solid plastic with nylon filler Thermoplastic blend of PVC and PET

Correct Answer:

Alternating layers of fiberglass cloth and resin over a mold.

Explanation:

Fiber Reinforced Plastic is a composite made by embedding reinforcing fibers in a polymer resin. In most FRP parts, fiberglass cloth is laid up over a mold and saturated with resin, with multiple layers added before the resin cures. The fiberglass provides strength and stiffness, while the resin binds the fibers and transfers loads between layers, giving a strong, lightweight material. This arrangement—fiberglass fabric plus resin laid over a mold and cured—is what defines FRP, rather than metal substrates with coatings, solid plastics with fillers, or thermoplastic blends that don’t use a fiber-reinforced resin matrix.
