Hexcel manufactures a complete line of HexForceTM woven and non-crimp fabrics from carbon fiber. The range includes traditional fabrics (3K, 6K, 12K, 24K), flat-tow 12K and heatset-unit fabrics, plus non-crimp, multiaxial reinforcements.
Hexcel's carbon fabrics meet the specification requriements of BMS 9-8 as well as other major aerospace manufacturers' specifications for carbon fabric. These fabrics use fibers that are produced under stringently controlled conditions, extensive testing and documentation.
Our commercial carbon fabrics utilise many of the same carbon fibers that have been produced with less extensive testing and documentation. Standard Modulus carbon fiber, supplied to the commercial market, yields typical property values of 530KSI (GPA) for tensile strength and 34 MSI for tensile modulus. Higher performance carbon fabrics with increased tensile and modulus properties are available from Hexcel for special applications.

Multiaxials are made up of two or more layers of unidirectional fibers stitched together with a light polyester thread. We also offer multiaxials that are powder-bonded instead of stitched.
Multiaxials enable the user to process multiple layers of unidirectionals (the ultimate reinforcement form) in a single fabric form

OCV™ Unidirectional Fabrics provide excellent strength and stiffness along the fiber direction. They also provide the highest ratio of axial strength to weight. This combination of properties makes Unidirectional Fabrics ideal for demanding applications with a high aspect ratio (length to width ratio) such as wind blades, poles, and stringers. These fabrics are also useful in applications where a discrete area requires additional strength or stiffness. Wrapping of existing structural components, such as columns and beams, with Unidirectional Fabrics could also greatly increase the lifespan and performance of these critical load-bearing members. These fabrics are also commonly used in FRP pipe and fittings for increased strength.

HexPly® prepregs are specially formulated resin matrix systems, that are reinforced with man-made fibers such as carbon, glass and aramid. When cured at elevated temperatures, the themoset resin undergoes a chemical reaction that transforms the prepreg into a solid structural material that is highly durable, temperature resistant, exceptionally stiff and lightweight.
Initially developed for the aerospace industry, HexPly® prepregs are now used in a wide range of applications - from golf clubs to satellite arrays, and from wind turbine rotor blades to life-saving Formula 1 monocoques. Hexcel has its own in-house supply of carbon fiber and world class weaving facilities for the development of optimum reinforcement technologies to complement the prepreg resin formulations.
Prepregs are supplied to customers in roll form, to be stored frozen and defrosted before use. When cured at elevated temperatures and under pressure, prepregs form molded components that are extremely strong and stiff. A broad range of formulated resins are used to impregnate the woven and unidirectional reinforcements.
Epoxy resins provide the highest levels of toughness and good environmental resistance. Phenolic resins provide fire-resistance and bismaleimide resins provide high temperature resistance. Cyanate esters provide excellent dimensional stability and are used primarily for satellite applications.

With its unique combination of features - low weight /high strength, wide processing envelope and high temperature performance - prepreg compatible Divinycell HP is ideal for a wide range of applications in the marine, wind energy, transportation and industrial markets.
Temperature Performance
With its high processing temperature, Divinycell HP can be processed at a much higher temperature than other polymer core materials in general use, making it suitable for not only low but also medium temperature prepregs.
Its elevated temperature performance is not just beneficial to prepreg users. Its high residual strength and good dimensional stability also make it ideal for vacuum bagging, infusion and RTM (resin transfer molding). HP's elevated temperature performance also extends to the 'in service' life of the component. Divinycell HP will retain a high percentage of its mechanical properties despite long term exposure to high ambient temperatures.
Strength Performance
Divinycell HP exhibits at both ambient and elevated temperatures impressive compression and shear properties (normally the most important for a sandwich core material) that are better than other commonly used ‘elevated temperature’ core materials. The figures for shear strain show that HP has good ductility and energy absorption characteristics. Testing has shown that HP also outperforms linear cores in terms of slamming resistance.
Adhesion
Divinycell HP also excels is in adhesion. Peel tests have been performed using commonly used resin systems and prepregs with superior results to other cores used for prepregs.

AtlasFoam® is an expanded material of closed cells produced from a reticulated polymer of high strength and toughness in relation to the density.
AtlasFoam® is suitable as a core for structural sandwich, ideal for different applications in the marine industry, aerospace, wind energy and for all of those sectors in which lightness and high resistance are required, as well as resistance to environmental degradation (internal or external environments, contact with water, presence of oils, etc.).
The products of SotecoFoam are extremely versatile because they combine different qualities in single products. For this reason they can be used for the construction of main structures, thanks to their mechanical resistance, for the laying of wall plugs, partitions, protection structures, and in every other application in which good insulation and inalterability are required in different environmental conditions.

SotecoFoam created FenixFoam®, the innovative expanded structural panel made of fine closed cells suitable for the transportation industry, aeronautics, marine and for all those areas that require materials with good fire reaction.
In order to achieve FenixFoam®'s special formulation, different mineral fillers have been used.
These undergo a reaction ahead of the flame front, providing substances that steer the polymer decomposition towards the formation of graphitic-refractory substances.
These hinder the fire propagation and only permit the development of low-density smoke.
FenixFoam® is tested in certified laboratories for fire reaction according to the AFNOR rules for smoke opacity and gas combustion during pyrolysis. Because of its behaviour in fire circumstances, it is classified in the F1 and M1 classes. When it is involved in a fire, the development of FenixFoam®'s low-density smoke does not prevent anyone from reaching the emergency exits. The low toxicity of the gas is also very important because it does not prevent people from escaping the fire.

CrioFoam® is a structural foam characterized by a low thermal conductivity, due to the special formulation and type of of expanding agents, which permits energy savings of up to 20%. The foams are composed of polymeric structures of cross-linked high density for an excellent resistance to styrene, suitable for unsaturated polyester resins, epoxy resins, and vinylester resins. Not only does its regular and fine structure guarantee excellent thermal properties, but also excellent mechanical properties and dimensional stability.
CrioFoam® is available with fire reaction to the DIN B2 standard.
CrioFoam® finds its application in the construction of sandwiches for all those applications in which very good thermal insulation is required, such as in the case of industrial containers and refrigerator vans for the preservation of food products.
