RP542-4 system for broadloom and unidirectional prepreg

Designed as an intermediately toughened system, complimenting both its RP542-1 and super-toughened RP549 systems, PRF's new RP542-4 system is producing excellent results on unidirectional and woven carbon fabrics.

The mechanical testing carried out shows the system to have excellent Tensile, Compressive, Flexural and Interlaminar properties and a relatively high Tg of 138°C after curing at 120°C. The onset Tg can be improved by 20°C to 120°C after post curing at 140°C for 2 hours. Adding to its usability, the system also has an out life of 60 days at 20°C.

The system is now in manufacture on 300gsm and 600gsm unidirectional carbon and PRF’s wide range of high quality woven fabrics in a variety of fibre types.
