AI Article Synopsis
- Electrospun veils made from copolyethersulfones (coPES) were created to act as interlaminar layers in carbon fiber/epoxy composites, with varying thermoplastic content (10-20 wt%).
- The process involved impregnating neat resin samples into coPES veils and then infusing dry carbon fabrics with these veils to construct reinforced laminates.
- Curing processes for the samples involved initial heating at 180 °C and then post-curing at 220 °C, resulting in significant differences in viscoelastic and morphological properties between the carbon-reinforced and neat resin samples.
Article Abstract
Electrospun veils from copolyethersulfones (coPES) were prepared as soluble interlaminar veils for carbon fiber/epoxy composites. Neat, resin samples were impregnated into coPES veils with unmodified resin, while dry carbon fabrics were covered with electrospun veils and then infused with the unmodified epoxy resin to prepare reinforced laminates. The thermoplastic content varied from 10 wt% to 20 wt%. TGAP epoxy monomer showed improved and fast dissolution for all the temperatures tested. The unreinforced samples were cured first at 180 °C for 2 h and then were post-cured at 220 °C for 3 h. These sample showed a high dependence on the curing cycle. Carbon reinforced samples showed significant differences compared to the neat resin samples in terms of both viscoelastic and morphological properties.
