Fire retardant glass fiber fabric / epoxy resin prepreg Gurit
EP137

EP137

- Fiber reinforced thermosetting preimpregnated materials for aircraft parts(e.g.passenger floor).
- Woven fabric of E-glass filament yarn Style 0180, 48 g/m2, plain weave, preimpregnated with 40% epoxy resin EP137 (125°).
- Low-smoke, highly toughened and self-extinguishing epoxy resin system
- Very good FST behaviour
- Excellent adhesion to core materials
- Improved storage conditions at -5°C

EP137-03-40 consists of a E-glass fabric Style 0180, impregnated with the epoxy resin EP137. The highly-toughened resin matrix is a 125°C curing system with a high flameretardancy and low smoke behaviour at fire and provides excellent properties such as high interlaminar shear strength, adjustable tackiness and retarded flow during processing.

The prepreg is perfectly suitable to complement high performance light-weight composite structures meeting the highest requirements of structural interior applications as such as the passenger floor where it is used as a top layer to avoid electro-galvanic corrosion of carbon structure with aluminium and improve overall impact behaviour of the panels.

Both monolithic and sandwich structures can be easily manufactured with this prepreg. The curing can be performed by press, vacuum and autoclave moulding at a temperature range between 120°C and 155°C and a pressure of at least 0.07 MPa.

Such composite structures can be exposed easily to temperatures in the range of -55°C up to +90°C.
