Understanding of how fractures move through a material.

What is it about?

Fracture properties of a wide range of filled unsaturated polyester resin composites have been investigated with respect to filler size, shape, loading and adhesion to the matrix resin. Mechanisms are proposed for the fracture behaviors found, based on geometrical considerations of interacting filler particles and stress concentrations which result from them.

Why is it important?

Its impact on the strength & durability of materials in practical usage.


Dr Stephen K Brown

A simplified mechanism of fracture behaviour at different loadings & interfacial bonding of fillers is proposed.
