In recent decades, there has been an increasing interest in the use of carbon fiber reinforced plastic (CFRP), in the aerospace,renewable energy and other industries, due to low weight and relatively good mechanical properties compared with traditional metals. However, Carbon fiber composite materials have relatively poor properties in the direction transverse to their reinforcing fibers, with notably low resistance to impact. Impact events are inevitable during the lifetime of a composite structure, occurring during both service and maintenance in the form of collisions with stones or tools. Such events can cause extensive internal delamination.This damage, while often difficult or even impossible to detect
at the surface of the material, severely degrades the load bearing capacity of the structure [1].
