HexTow™ fibers from Hexcel are produced in a continuous operation in which the polyacrylonitrile precursor undergoes a series of precisely controlled processes. Exposure to extremely high temperatures chemically changes the precursor, yielding high strength-to-weight and high stiffness-to-weight properties through oxidation, carbonization and graphitization. The successive surface treatment and sizing stages improve bonding and handleability. The resulting carbon fiber is stronger than steel, lighter than aluminum and as stiff as titanium. It can be supplied in two basic forms: Continuous Fiber and Chopped Fiber.

Carbon products: We manufacturer all the grades of 'standard' multiaxial carbon fabrics, plus many unique products that are only possible with our fibre-spreading technology. We work with all the premium fibre producers, and most of our products are made from HS T700 or equivalent.
All fabrics available cut into tapes
These are only our standard products. We also manufacture a very large range of bespoke fabrics to exactly meet our customers' needs.
ST = Stabilised (lightweight yarn layer in 0 &90)
HD = High Drape
UB = Unbalanced

MAPEWRAP C BI-AX : Balanced high strength bidirectional carbon fibre fabric. Mapewrap C BI-AX is a bidirectional carbon fibre fabric characterised by a high modulus of elasticity and very high tensile strength. Mapewrap C BI-AX is suitable for repairing concrete structures and to improve flexural and shear strength of reinforced concrete structures damaged by physical-mechanical action, for confinement of axial loaded or concrete elements subjected to compressive and bending stress and for seismic strengthening in earthquake areas.
MAPEWRAP C UNI-AX : High strength unidirectional continuous carbon fibre fabric. Mapewrap C UNI-AX is a uni-directional continuous carbon fibre fabric characterised by a high modulus of elasticity and very high tensile strength. Mapewrap C UNI-AX is suitable for repairing reinforced concrete structures damaged by physical-mechanical action, for confinement of axial loaded or concrete elements subjected to compressive and bending stress and for seismic strengthening in earthquake areas.

We offer a broad portfolio of high-performance textile products made from carbon-, glass- and aramid fibers. As a leading manufacturer of carbon products we can draw on several decades of experience. The majority of our reinforcement materials are processed into components made from composite materials. Common processing methods include wet lamination, molding, RTM, and the production of prepreg materials.

The carbon fibres are composed of a minimum of 95% of graphite structure. The carbon fibre is generally produced from a polymer called polyacrylonitrile (PAN), which is spun first, and then in successive controlled stages is carboninized at about 1800°C.
The result of this process is a very light fibre (density 1,78 g/cm3), very resistant (Tenacity 4800Mpa, modulus of elasticity 240 GPa) and flexible, therefore it is quite easy to process.
Characteristics of carbon fibre
- Elevated resistance to traction
- Elevated modulus of elasticity (traction and compression)
- Extremely light weight
- Low elongation at break
- Very high flexibility
- Easy to impregnate
- Highly fragile
- High cost
- Low resistance to impact
- Electrical conductivity
