Shear yielding thermoset matrix

As discussed in Chapter 12, crazing does not occur in thermosets therefore, the only possible response of the matrix to a load is to promote localized shear yielding between particles. 

Figure 4.30 Stress transfer to a single fibre in a thermoset matrix, under tension in the x direction. The graph shows the variation of the fibre tensile stress and the interfacial shear stress, when the interface yields at both ends of the fibre.
