Epoxy resins (EP) are characterised by high ductility and excellent ageing resistance. Components made of EP composite materials exhibit low fatigue even under high alternating loads. Consequently, they are preferred for applications subject to high static and dynamic loads. Bonding capacity on textile reinforcing fibres is outstanding.
Due to the low shrinkage behaviour during the curing process, the moulded parts have a high degree of dimensional stability. An EP resin system consists of a resin component and one or more curing agents, which usually differ in terms of their reactivity (processing time and curing speed). The mixing ratio of resin to curing agent is fixed and must be strictly complied with.
The reactivity of the system cannot be influenced by varying the proportion of curing agent. Incorrect dosing inevitably results in a decline of the mechanical, thermal and chemical properties of the laminate.
