Description

The aerospace industry is increasing its use of composite materials because of their: high strength and stiffness to weight ratio, low thermal expansion and resistance to fatigue and corrosion. Furthermore, their elastic and thermal properties can be tailored to suit anticipated service loads. Unfortunately, the very nature of these fibre reinforced polymers makes them prone to several types of damage. Among these damage modes, interlamina disbonding, or delamination, has been found to be the most serious. This form of damage can be induced by relatively low energy impacts such as a carelessly dropped tool, runway stones, hail and once started the region of damage can grow with the load cycling incurred in normal operation.
