CYCOM® 5270-1

CYCOM® 5270-1 is an advanced bismaleimide prepreg resin available with glass and carbon fabric, designed for high temperature use. CYCOM® 5270-1 has similar mechanical properties to CYCOM® 5250-4, has a damage tolerance equivalent to epoxy with low moisture absorption, does not produce any volatiles during the 375°F (190°C) cure and can be processed as RTM. A post cure at 480°F (249°C) is required to reach a service temperature as high as 350°F (176°C)

Typical applications include aircraft cowlings, thrust reversers, pylons, hot ducts and various areas where a high service temperature is required.

Features and Benefits 
- Epoxy-like processing, no volatiles evolved during cure 
- Can be processed by RTM 
- Damage tolerance equivalent to epoxies 
- No MDA or toxic components 
- Tg stabilized to thermal aging, which provides stable mechanical properties
