The C86 / G86 series is a phenolic resin flame-retardant prepreg manufactured using a modified phenolic resin impregnated into carbon fibre fabric (C86) and E-glass fibre fabric (G86). The resin system combines rigidity with outstanding flame resistance, delivering excellent drapeability and mechanical performance.
- Low heat release rate during combustion
- Low smoke density — suited to enclosed passenger environments
- Meets fire retardant grade EN 45545, RE HL3
- Available in press moulding and autoclave processing
- Curing at 130–150°C with a short gel time of 10–15 min at 130°C
- Fibre options: carbon (Toray / Aksaca) or E-glass (2400 Tex)
Fire Safety Compliance: Tested by DSC at 10°C/min heating rate. Meets EN 45545 rail transit fire retardant requirements at Hazard Level RE HL3 — applicable to aircraft, high-speed rail, and marine interior decorative structural components.
