Question

If a laminate consists of pairs of layers with identical thickness and elastic properties, but with orientation in opposite sense (+θ and –θ) with respect to the laminate reference, then the laminate is called

• A. Angle ply laminate
• B. Symmetric angle ply laminate
• C. Cross ply laminate
• D. Balanced laminate

Hint:

Balanced laminates improve mechanical stability in composites.

Answer 1

The Correct Option is D

Balanced laminates have pairs of layers at +θ and –θ, which balances the in-plane shear forces and helps avoid coupling effects.
