Elastic modulus of fibre-reinforced composites

The objective of fibre reinforcement is to endow a lightweight matrix with high strength and stiffness. A critical fibre length, 4, is necessary to achieve this  

In practice, the fibre orientation, concentration and distribution all contribute to the final properties of 

This is the same equation as the upper bound for large-particle composites. 

The fraction of the load carried by each component is given by
