Glass fibre
Find glass fibre for manufacturing composite parts and moulds. Explore glass fibre fabrics, glass fibre chopped strand mat, tapes, multiaxial reinforcement and spray-up rovings for your project. These are reinforcement fibres for glass-reinforced plastics (GRP), not insulation products.
What to consider when choosing
Glass fibre for the laminate's application
For marine parts and large components, woven roving and fabric/glass-mat combinations offer different constructions. Glass fibre combinations may join stitched layers or include an inner resin-flow layer for closed moulding; first decide between hand lay-up, infusion and injection. For spray-up, the catalogue includes glass fibre roving specified for use with unsaturated polyester resins. It is a different format from glass fibre fabrics and mat for hand lay-up.
For moulds, parts and waterproofing laminates, glass fibre mat selection also depends on the binder. One specific mat reference covers initial layers near the gelcoat; it is not the same as a surface veil or woven fabric. Silionne fabrics include references described for model making, windsurfing, kitesurfing and automotive work.
For directional reinforcement in wind-turbine blades or boats, compare UD glass fibre bands and fabrics. Tubular sleeves make tubes and are dry materials, not finished parts. Multiaxials combine layers with different fibre orientations; choose their arrangement to suit the laminate design.
When buying, relate orientation and format to the laminate area and check the resin admitted for the reference. These GRP reinforcement fibres do not replace thermal insulation products.
To choose the resin for your laminate, browse polyester resins for hand lay-up or, for epoxy projects, epoxy resins for hand lay-up and epoxy resins for infusion and RTM. Check the technical data sheets for the reinforcement fibres and the resin to confirm that both materials suit the planned process; these selections do not imply compatibility between all their products.
