Delivering interlaminar reinforcement in composites through electrospun nanofibres

Electrospun nonwoven veils comprising thermoplastic fibres (average diameter 400–600 nm) based on polysulfone (PSU), polyamide (PA-6,6), and polyetherimide (PEI) have been fabricated and used as interlaminar reinforcements in carbon fibre composites containing a commercial epoxy resin (8552/IM7).
