REVIEW ON METHODS TO REDUCE DELAMINATION IN COMPOSITE LAMINATE

Composite material has much more advantage and applica tion than metal. This is mainly because of their excellent mechanical properties with low density and ease of manufacturing, but failure mechanism of composite is unpredictable, testing of composite is very costly. The main reason for damages in composite materials are inter - laminar de - bonding, delamination, micro - cracks, micro - buckling and inclusions among these damages delamination is one of the major defects observed in composite structure. In this paper, we are reviewing the methods to reduce occurrence of delamination in composite laminate by understanding the effect of number of ply and effect of stiffener on delamination in composite laminate
