Chomarat Solutions – The Widest Offer in Composite Reinforcements

To read more on Chomarat Solutions please click here.

Chomarat has a distinctive range of technologies for designing and manufacturing the widest offer in composite reinforcements. Some composite reinforcements include:

Adhesive Solutions

Chomarat offers two adhesive solutions to help the lay-up of reinforcement in closed mould processes.

  • FX: Facilitator of Reinforcements Positioning – FX is an adhesive solution that enables the positioning of Chomarat glass reinforcement products. The key function of FX is to ease the production of large parts with complex geometries in closed mould processes. It is well suited for markets like transportations and marines
  • Easytape – Easytape is a range of glass tapes coated on one or both sides. The adhesive solutions maintain reinforcement into the mould and are adapted for bigger parts and complex geometries.

Ballistic Fabrics

Chomarat has a range of ballistic reinforcements that are designed for ballistic protection known as Hard Armour. Numerous fibres can be used, glass or aramid and the choice of fibre is dictated by the level of performance needed: weight, type of threat: bullets, mines, IEDs (Improvised Explosive Devices).


Braid is a tubular reinforcement that optimises fibres orientation. It offers good deformability and mechanical characteristics by being a continuous reinforcement. 

Core Materials

ROVICORE™ is our range of Core Materials. It is a reinforcement made with a synthetic non-woven core and chopped glass fibres mechanically stitched together. It can be used for all Closed mould process requirements.


  • Core resilience and compressibility. To adapt to the different thicknesses of parts.
  • The high permeability of the synthetic core.
  • Adaptable thickness.
  • Easy to form in angles and more complex shapes. Time and labour savings.
  • Good surface aspect.
  • Lack of chemical binder for a good impregnation of the reinforcement.


Flow Media Materials 

The range of flow media materials designed by Chomarat aims to ease the resin flow during the infusion process to then replace external flow media. According to the final part properties, various reinforcements are available; however it brings cost-saving benefits and good resin flow.

Needled Multi-Layers 

Needled Multi-Layers are a combination of woven roving, stitch-bonded by needling to a mat without chemical bonding. By using the needling methods adds volume to fibres and therefore adds thickness to parts. This range is particularly recommended for the manufacture, with the pultrusion process, of parts requiring mechanical properties.

Wind power, a growing world market

The wind power industry continues its growth, with 55 GW installed during the year 2016. This trend can be explained by two factors, environmental considerations and economics.

The COP21 agreements have created new growth opportunities for clean energy solutions such as wind power. China, India and the United States, among others, have increased their investments in this area; as a result, the global cumulative capacity is expected to reach 2000 GW in 2030, compared to 500 GW at the end of 2016. Concurrently, thanks to its sharply declining cost, wind energy is becoming a competitive alternative to fossil fuels.

Cost reduction, however, remains a challenge for this industry. The increase in turbine performance and the development of offshore technology (sea-based wind power) have contributed to reducing costs. These changes have created new structural constraints for wind turbine blades, which must withstand extreme weather conditions. The size of these blades is constantly increasing (now in excess of 80 meters) while an optimal weight/power ratio must be maintained.

To accompany the advances in this industry, which is constantly looking to optimise its materials and processes, Chomarat has developed new textile solutions for composites.

The work carried out in collaboration with Professors Stephen W. Tsai of Stanford University and Sung Ha of the University of Hanyang, have shown that blade design could be optimised in terms of weight, performance and cost, through the use of multiaxial reinforcements (NCF) based on fibreglass (G-PLY™) and/or carbon (C-PLY™).

Using the G-FLOW™ range of structural and vacuum-draw systems developed by Chomarat, results in shorter blade manufacturing time  while lowering cost by about 13% compared to an external flow medium.

Chomarat is a worldwide industrial presence.

The implantation of Chomarat in Europe, China, Tunisia and the United States guarantees our customers a competitive, high-quality global offer.

Industrial investments made in recent years, particularly in its production capabilities for multiaxial reinforcements, demonstrate Chomarat’s commitment in these high volume markets.

The challenges of the oil and gas industry

Another alternative for meeting our energy needs is to drill deeper and deeper into the ocean floor to extract fossil fuels.

This requires designing new flexible tubing, capable of withstanding the high pressures and extreme conditions found inside a well at depths of 3000 meters. Chomarat is meeting these challenges by creating special reinforcements which combine technological know-how and high performance fibres (aramid, carbon, etc).

Chomarat is an historical actor in the sporting equipment market.

The company was one of the very first players to participate in the development of composites for skis. Exceptional know-how in ribbon weaving is one of its many assets.  The flexibility of this technology is particularly well suited to the ski manufacturing process. It allows production of narrow widths with a preferential axis at 0°, using a wide variety of materials (glass, carbon, aramid, basalt, natural fibres, etc.). Ribbons have the particularity of combining technical function with aesthetics.

Chomarat also uses multiaxial technologies, widely praised by ski manufacturers.  Available in various constructions (biaxial or triaxial), these NCF reinforcements can be combined with fabrics, cut into strips, and made from different fibres.

Combining design and structure.

More recently, Chomarat has developed C-WEAVE Design, a range of carbon fabrics combining original design and structural performance: 100% carbon reinforcement, or carbon/Innegra™ hybrid reinforcement, providing shock resistance and vibration damping, particularly appreciated in sporting equipment.

With C-WEAVE Design, Chomarat has broadened its offer to include products for premium quality appearance, intended for demanding markets. The size of the design is particularly tailored for large parts such as surf boards or hydrofoils.

Innovative reinforcements for winter sports.

The sporting equipment industry is constantly searching for ways to optimise its processes and the quality of its products. In order to meet the accompanying demand, Chomarat has developed C-PLY™, a range of carbon-based multiaxial reinforcements (NCF).

Close collaboration with Steve W. Tsai, Professor Emeritus at the University of Stanford, has led to the development of C-PLY™ for tight angles (20 to 30 degrees). This patented, fully innovative reinforcement has allowed us to improve the fatigue resistance and lower the weight of parts with preferential direction such as skis, for better control of dynamics and behaviour on different types of snow.

The performance of Chomarat reinforcements has also proved useful for tubular structures such as bike frames, for which the stiffness/weight ratio of each tube section must be calculated and optimised. Fabric or multiaxial is then selected based on fibre orientation, but also on the required final appearance.

Innovation, at the heart of the Chomarat strategy.

The Chomarat Group participates in the I-COMP Sport applied research consortium, whose studies are hosted in Singapore at the Institute for Sports Research, in the prestigious Nanyang Technological University.

One of the developments, conducted jointly by Chomarat and the ISR, demonstrates the possibility of using an automated technology which combines RTM and dry, preformed shapes to produce a high performance racquet prototype. This technique, combined with optimised reinforcements, is an alternative to conventional pre-impregnated technologies, thereby reducing human error while guaranteeing consistent quality.

Composites in the railway industry.

Thanks to their useful properties, composite materials have become indispensable in the railway construction market. They provide weight reduction (which reduces track wear and increases transport capacity), corrosion resistance (which lowers maintenance requirements), and functional integration.

Railway parts must also meet European standards for fire/smoke resistance (EN 45545). In this context, Chomarat has developed ROVICORE™ FR (Fire Resistant), a sandwich reinforcement based on glass fibres. Used in mould processes and combined with suitable resins and gelcoats, ROVICORE™ FR is the proven solution for manufacturing composite parts that comply with fire and smoke standards.

Composites in industrial vehicles (buses, trucks, farm equipment).

Just like light vehicles, industrial vehicles must meet CO2 emissions regulations. Given this new legislation, combined with a desire to lower energy costs, weight reduction has become a major axis of development for manufacturers.

In this context, composites offer new alternatives to metals, by providing strength and lightweight properties.

Chomarat has been serving the bus and truck market for several years. It has developed a range of woven fabrics, G-WEAVE, and laminates that meet manufacturers’ requirements for structural parts and refrigerated truck panels.

With its Rovicore™ range, intended for closed-mould processes (RTM, RTM Light, etc.), Chomarat is able to comply with changing environmental standards (reduction of VOCs) and with the quality, consistency and productivity requirements of its customers. Rovicore™ is specifically used for manufacturing hoods, roof risers, spoilers, etc.
