Das neuartige Material kann sogar unter Wasser ausgehärtet werden.
A special formula for epoxy resins has been developed at TU Wien, which can be used for fibre-reinforced composites in aerospace, shipbuilding and automotive manufacturing, or even for underwater renovation. This is achieved merely by irradiating any part of the resin with light. Within seconds the new material can be completely transformed. Initially, the material is transparent and either in liquid or paste form; then, when any part of it is irradiated with the appropriate light, the entire resin begins to solidify and takes on a dark colour. The special epoxy resin formula that makes this possible has been patented by TU Wien. Now, researchers have even successfully carried out the process underwater. This means that the new epoxy resin can be used for jobs that, up until now, had been very difficult to carry out, such as filling underwater cracks in bridge pillars or dams, or repairing pipes during ongoing operation.
