Composite Analysis for Modulus and Strength in the Longitudinal Direction

This video presents a lecture on the theoretical analysis for elastic modulus and strength of a unidirectional continuous fibre composite in the longitudinal direction. You will learn about the calculations of the elastic modulus and strength of a composite if you know those properties of the fibre and the matrix and the volume fraction of the fibre. The video also explains why there is no strengthening in such a composite if the fibre volume fraction is below a critical value.
Summary:
Best reinforcement for a composite can be achieved in unidirectional continuous fibre composite.
Both, modulus and strength of an unidirectional fibre composite in the logitudinal direction can be predicted by the rule of mixture.
There is a critical fibre volume fraction below which fibres do not provide any reinforcement to the matrix.
