Abstract
A laminated composite material comprising a polymeric matrix material and plurality of fiber layers is heated to a first pre-determined temperature which is defined as the temperature at which there is a first pre-determined time interval until the matrix material reaches its gel point. The first pre-determined time interval being defined as the time required to insert the required quantity of through-thickness reinforcement fibers into the laminated material. A plurality of holes is formed in the laminated material; each hole being formed by inserting a needle having a conical tip, into the laminated material. A reinforcing element is then inserted into each of a respective one of the plurality of holes.
