Question

Longitudinal strength of fiber reinforced composite is mainly influenced by:

• A. Fiber strength
• B. Fiber orientation
• C. Fiber volume fraction
• D. Fiber length

Hint:

In fiber reinforced composites, maximizing the fiber volume fraction is crucial for improving the strength properties, as more fibers mean greater load-bearing capacity.

Answer 1

The Correct Option is C

The longitudinal strength of a fiber reinforced composite is primarily influenced by the fiber volume fraction. The fiber volume fraction refers to the proportion of the composite that is made up of fibers, and this directly affects the mechanical properties of the material. A higher fiber volume fraction generally leads to better strength characteristics, as the fibers provide the primary load-bearing support in the composite material. While other factors like fiber strength, orientation, and length also play a role, the fiber volume fraction has the most significant impact on the longitudinal strength.
