Der einfluß von faseroberflächen auf die matrixhärtung bei faserverbundwerkstoffen

Abstract: SUMMARY:The influence of extraction of reinforced fibres on surface properties and the curing reaction of epoxy resin matrix in composites were investigated. With increasing fibre surface polarity, as the result of the extraction, the resin wettability was improved and the reaction rate of curing of the epoxy resin matrix increased. The wettability and the reaction rate oppositely decreased with decreasing fibre surface polarity.

“…Kinetics modeling of prepregs curing is not easy to evaluate owing to the many concomitant reactions occurring contemporary and/or in sequence on several comonomers and initiators, to the possible presence of additive or accelerants and to the intrinsic difficulty of monitoring such a complex system that ends up in an insoluble network . Moreover, in prepregs the situation is made even more complex by the influence that different fibers might have, depending on surface chemistry and sizing treatments . When studying curing kinetics of epoxy resins by DSC, both isothermal and dynamic methods can be adopted.…”
