Delamination or cracking
In the past the weakness of regular composite constructions (sandwiches) was their delamination, a problem caused by the skin coming loose from the core. Delamination mainly occurs after impact load, followed by fatigue load. In bridges this could be the case after cracking damage followed by passages with a wheel print. InfraCore® technology is still the only technology that offers a solution for delamination. This solution cleared the way for the use of fiber-reinforced plastics in Infrastructure.
