Abstract
The aim is to study methods to improve the fire properties of carbon fibre reinforced epoxy composites with interlayers without compromising structural performance, i.e. using a carbon fibre veil with expandable graphite, an intrinsically flame retardant thermoplastic film or a carbon fibre reinforced thermoplastic (CFTP) layer. The CFTP layer seems the most promising, with a significant improvement in fire properties as determined with cone calorimetry, while the mechanical performance of the modified composite appears unaffected.
