Fiberglass
Most used type of material in composite industry. Can be widely found in different constructions, automotive and marine industries. Different tyoes of fiberglass are avaliable, but most used are chop stranded mat and vowen fabric( vowen rowing, various axis materials.)
Aramid (Kevlar)
Organic fiber with high strenght, excellent elasticity and wear resistance. Usually is combned with other materials and widely used in sports equipment and automotive production with high requirements.
Carbon fiber
Material made from carbon fibers with very light weight and strenght. Approximately 1 layer of carbon fiber is equal in strenght of 5 fiberglass layers of same thickness. Usually is used to manufacture automotive parts/ sports equipment, marine industry etc.
Hybrid
A combination of Aramid and Carbon fibers which includes in itself best of both worlds. The stiffness and weight of carbon fiber and excellent elasticity of Aramid fibers.
Polyester
For hand lamination Polyester resin is most widely used for low stress and temperature parts. Avaliable at low cost and in wide array of types. Cons – shrinkage 7-8% and bad bonding with Aramid and Carbon fibers.
Vinylester resin
Resin for hand lamination and vacuum infusion with mechanical propertes that are just a class lower than Epoxy. Can be combined with any gelcoat. Cons – shrinkage close to Polyester resins.
Epoxy resin
High strenght and low weight. Ideal for parts that are under load and temperature stress. Depending on resin type, temperature resistance over 200ºC can be achieved. Shrinkage 1-2%. Ensures best adhering between layers of laminate. Cons – doesn’t bond with omindirectional glass fibers(matt).
Urethane resin
Newest resin type with great mechanical properties which surpass all of the previously mentioned resins. Great bonding with all fibers and sandwitch materials. Only con for this resin – can only be used with vacuum infusion technology.
