Question

If a laminate consists of pairs of layers with identical thickness and elastic properties, but with orientation of +θ and -θ with respect to the laminate reference axis, then the laminate is called as

• A. angle ply laminate
• B. symmetric Angle ply laminate
• C. quasi isotropic laminate
• D. balanced laminate

Hint:

Symmetric layouts in composite laminates minimize warping and residual stresses, leading to more predictable and stable structural behavior.

Answer 1

The Correct Option is B

A symmetric angle ply laminate is made of layers where the fibers are oriented at alternating angles of +θ and -θ, symmetrically about the central plane. This arrangement ensures balanced mechanical properties and stability under various load conditions.
