Hexcel manufactures aramid fabrics for use in aerospace applications as well as marine, tooling and recreational products where high strength, low weight, and impact resistance are essential.
Aramid fibers are 43 percent lighter than fiber glass, with a density of 1.44 g/cc compared to 2.55 g/cc for fiber glass. They are twice as strong as E-glass, ten times as strong as aluminum and approach the strength of high strength carbon on a specific tensile strength basis.
Aramids display excellent dimensional stability with a slightly negative coefficient of thermal expansion (-2.4 X 10-6/ºC.) They are resistant to chemicals with the exception of a few strong acids and alkalis.
Aramids have excellent stability over a wide range of temperatures for prolonged periods. They show essentially no embrittlement or strength loss at temperatures as low as -320ºF (-196ºC). Aramids do not melt or support combustion but will start to carbonize at approximately 800ºF (427ºC).

Woven roving glass fabrics of KROSGLASS S.A. are produced on weaving looms from rovings ER 3003 and ER 3003 B. These rovings are made of glass fibers of alkali-free boron-aluminium-silica glass of type E (contents of alkali metal oxides less than 1%). The fabrics are made of direct roving having filament diameter 11 ÷ 22 µm (depending on linear mass of the roving used). Rovings with chemical active vinyl-silane or metacrylosilane coating are used in fabric production, thus enabling a direct application of fabrics in production of laminates (no additional operations of surface finishing off are required), and good polymer-to-glass adhesion is ensured.

|
|
OC® Woven Rovings are either single-end or multi-end rovings woven into fabrics for uses such as wall reinforcements and rib or laminate reinforcements. Compatible with most resins, woven rovings provide rapid wet-out and excellent dimensional stability during product handling. OC® Woven Rovings are made in a variety of assorted weave patterns for design flexibility and high strain values, and can be engineered for high impact-resistant applications.
|
|
|
OC® Knitted Fabrics are knitted layers of directional rovings either with or without a supporting chopped strand mat or veil. The layers are stitched together for better handling and dimensional stability during lamination. The precise alignment and positioning of the rovings give high tensile strength and a smooth surface finish in applications such as leisure boats.

Taconic silicone coated fabrics exhibit very similar properties to fluorocarbon resin and PTFE coated fabrics.
Excellent Release properties up to 230°C
Silicone coated surfaces exhibit excellent release characteristics and will release adhesive and viscous materials which often adhere to a fluorocarbon resin.
Good Chemical Resistance
Silicone coated fabrics exhibit high resistance to attack from mild alkali, non-oxidising acids, most salts, mineral lubricating oil, air, moisture and sunlight.
Superior Abrasion Resistance and Flex
Silicone coated fabrics offer a tough coated surface with high abrasion and flex resistance. Silicone coated fabrics, however do not exhibit the low friction surfaces or self lubricating properties of fluorocarbon resins.
Super Dielectric Properties
Silicone coated fabrics are excellent electrical insulators in tough environments.

Glass fibre is one of the most versatile fibres. It has excellent mechanical properties, excellent resistance to fire, very thermal shrinkage levels to guarantee good dimensional stability at high and low temperatures, excellent resistance to chemicals and furthermore is available in a wide range of yarn counts enabling the final user to choose the best combination between light weight, resistance properties and price.
Glass fibre is a good isolation material, and does not absorb humidity, plus its low dielectricity constant renders it particularly suitable for electrical applications.
Glass fibres offer a good balance between the cost of the product and the performance levels requested, a high resistance to compression and excellent compatibility with resins. They can also be used in combination with fibres of carbon or para-aramid (hybrid fabrics), giving an excellent balance between properties, weight and a subsequent reduction of costs.
Characteristics of glass fibre
- Low cost
- High resistance to compression
- Easy to wet out with resins
- Availability of different types of glass depending on the application
- Higher weight compared to other fibres when used in composites
- Low Modulus of elasticity

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
|
|
Hybrid fabrics allow to optimize the different chemical - physical properties of the fibres to obtain synergy between them, together with a good compromise on costs.
It is therefore possible to combine in the same fabric the rigidity of carbon fibres with the impact resistance of para-aramidic fibres, or the better adhesion of the resins to glass fibres with the mechanical and anti-ballistic properties of para-aramidic fibres.
