Discontinuous fibres
In a fibre-reinforced composite the matrix has the task of transferring the
externally-applied load to the fibres. This is done by shear forces at the fibre-
matrix interface. The extent to which this can be done depends on the surface
area of a fibre and hence this is a vital factor in determining the strength of a
composite. Figure 16.5 shows the stress transfer from a matrix to a fibre with
fibres ...
