Investigations into lightweight solutions for epoxy composite fire property improvement

摘要

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.
