Abstract
Synthetic rubber/thermoplastic blends were electrospun from their solutions. The rubber was a solid acrylonitrile/butadiene/acrylic acid copolymer and the thermoplastic was polyacrylonitrile. The aims of this study were to identify suitable systems and processing conditions for obtaining rubber-based electrospun nanofibers, to investigate the ability of an epoxy resin system to impregnate and swell selected hybrid rubber/thermoplastic mats, and to assess the impact of the nanofibers on the resin morphology and curing behavior. In particular, electrospinning trials were carried out varying the composition of the feed solution and process parameters, such as the applied voltage, the flow rate, and tip-to-collector distance. The morphology of the hybrid mats was characterized by scanning electron microscopy and their thermal properties by thermogravimetry. An epoxy resin-mat monolayer was also prepared and its fracture surface inspected; both rubber nanoparticles and PAN nanofibers were evident. The highly corrugated fracture surfaces suggest activation of local epoxy-resin toughening mechanisms. Altogether, the results encouraged the application of hybrid mats as interleaves in high-performance carbon/epoxy composites to contrast delamination. (c) 2019 Wiley Periodicals, Inc. J. Appl. Polym.
