Carbon fiber reinforcements are material consisting of fibers about 5–10 μm in diameter and composed mostly of carbon atoms. The carbon atoms are bonded together in so called crystals that are aligned parallel to the long axis of the fiber. The crystal alignment gives that outstanding high strength-to-volume ratio. Several thousand carbon fibers are clustered together which can then be woven into one fabric.
Summarizing, the advantages of carbon fibers which is one of the lightest and strongest fiber available are:
3 D Fabrics
sigma3D weaving techniques can be used to produce near net-shape preforms.
Spread Tow Fabrics
sigmaST range of spread tow fabrics are very thin, ultra lightweight, have near zero crimp and fewer interlacing points.
sigmaIF is a high modulus polypropylene fibre which can be used independently or in conjunction with other fibres to provide weight reduction, excellent levels of impact resistance and damage tolerance.
sigmaRF fabrics contain reclaimed carbon fibre, resulting in products that are sustainable and cost effective.
sigmaUD fabrics have carbon fibres just in one direction.
sigmaMX very flat, non-crimp fabrics from 100gsm with 2 layers and up to 1600gsm with a maximum of 9 layers, can be produced in widths up to 2540mm (100 inches).
2D Woven Fabrics
sigma2D fabrics are used in traditional fabric construction such as plain weave, twill and satin patterns and also more complex designs for aesthetic and performance applications.
