Impact damage on fibre-reinforced polymer matrix composite – A review

Abstract

As the application of fibre-reinforced polymer composite material continue to increase day by day, so the knowledge about the impact behaviour of fibre-reinforced polymer composite structures in the areas such as automotive and aerospace is very much needed. This article attempts a comprehensive review of recent literature in the broader area of impact damage. Testing methods and standard parameters as well as discussion of important aspects such as impactor shape, weight of impactor, velocity of impact, environment in which impact takes place are presented. Furthermore, the damage area, energy absorbed, contact time and many other considerations are discussed. Finally, an effort is made to review the research work by considering all aspects related to impact on such type of composite materials.

High-Velocity Impact Damage Behavior of Carbon/Epoxy Composite Laminates

“…(1)- (8). As discussed earlier, the use of nominal value of Z c in ly early failure initiation, and thus, the compressive failure mode in the 8) was thought to be under-predicted since only the shear stress was set Also, it was found from preliminary analyses that the predicted surprisingly negligible.…”

“…The above criteria were applied along with the failure criter of time step size, ultimate strain, and ultimate effective strain. The elements were c completely failed if the tension/compression strains or the effective strain were large (8) When the failure criterion was met along a particular direction, the stiffness was set to zero in a time interval of 100 times steps. The above criteria were applied along with the failure criteria by limit of time step size, ultimate strain, and ultimate effective strain.…”

“…MAT59 provides 8 failure modes in eqs. (1)- (8). As discussed earlier, the use of nominal value of Z c in eq.…”

“…The impact can be divided into low velocity and high velocity impact [3][4][5][6][7][8]. This classification depends not only on the projectile velocity but also on the material properties and the mass of the projectile, as well as the stiffness of composite laminates.…”

“…[6][7][8]12]), a limited number of studies on the high velocity impact damage behavior have been reported. Due to the complexity of the microstructural failure modes, the studies have been performed mostly by experiments.…”
