Fecha de publicación: | jul-2013 | Editor: | Elsevier | Citación: | Composites Part A: Applied Science and Manufacturing 50: 102-109 (2013) | Resumen: | The interfacial properties of epoxy composites reinforced with a single, plasma-treated fibre of either poly(p-phenyleneterephthalamide) (PPTA) or poly(p-phenylenebenzobisoxazole) (PBO) have been investigated with a focus on evaluating the effect of two non-oxidative (He and N2) microwave plasma treatments on interfacial adhesion properties. Tensile testing of single filaments revealed that their tensile strength does not diminish with the plasma treatments, despite the fact that their surface properties have been both physically and chemically modified. Interfacial characterisation by Raman spectroscopy indicated that the quality of adhesion was substantially enhanced following exposure of the fibres to microwave plasma treatment in either pure helium or pure nitrogen flows for just one minute. Such improvement was higher than that attained when O2 was used for blowing the plasma, under the same operational conditions. Moreover, no swelling effect was observed by AFM after e | Versión del editor: | http://dx.doi.org/10.1016/j.compositesa.2013.03.011 | URI: | http://hdl.handle.net/10261/332641 | DOI: | 10.1016/j.compositesa.2013.03.011 | ISSN: | 1359-835X | E-ISSN: | 1878-5840 |
