Prepreg Technical datasheets

GMS Composites Standard Prepreg Range & Technical datasheets

All standard high performance prepreg resin systems can be combined with a wide range of woven and multi-axial technical fabrics and fibres  based  on glass fibre, carbon fibre and aramid fibre, as well as other specialty fibres and hybrid fabrics  to  suit  application and performance  needs.

Custom design prepregs are also developed on request.

A range of resin films for vacuum moulding with technical fabrics and cores to product sandwich construction laminate parts are also available.
