Kinetic study of the cure process at the silica microfibres/epoxy interface using pyrene fluorescence response. Journal of Materials Processing Technology, 143-144, pp. 153-157.0924-0136https://hdl.handle.net/10016/26030In the present work, using the pyrene fluorescence response, the kinetic of the cure process at the interface of a composite material is studied. Silica microfibres were surface coated with 3-aminopropyltriethoxysilane (APTES), labelled with the pyrene group and dispersed in a mixture based on diglycidylether of bisphenol A (DGEBA) and ethylenediamine (EDA). The fluorescence of the pyrene was used to monitor, at different temperatures, the cure process at the epoxy/microfibres interface. A simple kinetic model was discussed from the fluorescence data and an apparent activation energy was obtained (Eₐ=33 kJ/mol). On the other hand, the cure process of the whole mixture was followed by FT-IR and by DSC and their results were compared with those obtained by fluorescence.5application/pdfeng© Elsevier 2003Atribución-NoComercial-SinDerivadas 3.0 EspañaFluorescenceCuringEpoxyKineticresearch articleMaterialesQuímicahttps://doi.org/10.1016/S0924-0136(03)00397-2open access153157Journal of materials processing technology143-144AR/0000004117
