Optimization — a tool in advanced materials technology

This paper demonstrates the use of simple optimization techniques in the production of two advanced materials - a fibre-reinforced composite laminate and a transformation toughened ceramic - having enhanced mechanical properties. Both example materials are based on a brittle matrix prone to cracking at very low applied stresses. The optimization process aims at altering the microstructure so that the materials have enhanced resistance to crack propagation without any undesirable side effects.
