Experimental Research of the Impact Response of E-Glass / Epoxy and Carbon / Epoxy Composite Systems
Keywords:low-velocity impact, absorbed energy, damage, delamination
The impact response of woven carbon/epoxy and E-Glass / epoxy composite systems on vehicle body structures has been
investigated – by considering energy profile diagrams and force-displacement curves. For low-velocity impact, dropweight
impact tests performed by EADS (European Aeronautic Defense and Space Company) Corporate Research
Center Germany have been carried out. Because the total amount of energy introduced to a composite specimen and the
energy absorbed by the composite specimen through the impact event are important parameters to assess impact
response of the composite structures they are considered in this paper. It is established that by increasing the impact
energy elastic deformation of woven E-glass / epoxy composite systems is 1.5 times higher than that of carbon / epoxy
composite systems that defines the formation of smaller areas of damage.
