At present, carbon fiber materials are widely used in various transportation equipment, such as automobiles, motorcycles, bicycles, yachts, airplanes, railways, etc. The special properties of carbon fiber composite materials make it more advantageous than other materials:
1, Material Comparison
Composite materials offer a distinct advantage over metals in stiffness, strength, and weight.
2, Design Freedom
Traditional sheet metal parts are processed on press brakes and stamping machines resulting in limited design freedom. Designs are limited to being prismatic and not aesthetically pleasing. In addition, localized yielding on bend edges in sheet metal parts can be starting points for cracks and could lead to unexpected part failure. Designers are also limited to using a single thickness throughout a part because of manufacturing reasons. This often leads to heavier parts. To bring down weight and remove material in regions of low stresses, additional manufacturing costs are endured and the amount of wasted material is increased.
Composite parts offer designers more freedom as molds can easily be produced to allow curved surfaces with no significant increase in cost. In addition, designers have control over the number of plies in particular regions allowing for pad-up in regions of concentrated stress and a reduced number of plies in areas of low stresses. This produces no significant increase in the costs required to manufacture the part and reduces the material consumption.

3. Security.

The tensile strength of carbon fiber composite materials is generally more than 3500Mpa, which is 5 times that of ordinary steel. The cockpit made of carbon fiber materials has very little deformation in the collision, which can effectively protect the living space of the drivers and passengers. The specially woven collision energy-absorbing structure breaks into smaller fragments in a high-speed collision and absorbs a large amount of collision energy (energy absorption is more than 3 times that of ordinary steel), which can effectively improve the passive safety of the vehicle.

4. Aesthetics.

Only a layer of varnish is sprayed on the surface, and the inner carbon fiber tows are clearly arranged in warp and weft or diagonal lines, which are dense and regular. The carbon fiber composite material is applied to the rear spoiler, rearview mirror, roof, instrument panel, sub-instrument panel, door core panel and steering wheel and other components with higher visualization to create the visual effect of vehicle technology movement.

Our technology:

1, Prepreg / Autoclave

Pre-preg is the “top class” fabric which during the manufacturing process undergoes impregnation with resin mixed with hardener. The resin provides protection against damage and imparts the required viscosity to ensure fabric adherence to the mold surface.

Pre-preg type carbon fiber has applications in Formula 1 racing cars, as well as in the manufacture of carbon fiber elements of sports bicycles.

When is it used? For manufacture of premium quality products of complex design that have low weight and outstanding appearance.

Our autoclave generates working pressure of 8 bar that provides optimal strength of manufactured products as well as a perfect appearance of composites without any trapped air defects.

After manufacture, components undergo varnishing in the paint spray booth.

2, Resin infusion

Resin infusion is a process whereby fabric in moulds is sealed with film/butyl tape and filled with a liquid resin. When the resin solidifies, the solid resin matrix binds the assembly of materials into a unified rigid composite.

This technique has applications in the manufacture of carbon sheets and other large items that have a moderately complex shape.

3, Manual laminating

Manufacture of high quality carbon fiber products requires costly technology. Dexcraft is one of the few companies that manufacture products using proprietary technologies of manual laminating that ensure high quality composites.

Our products manufactured using manual laminating technology present no defects related to air bubbles in the carbon fiber visual layer. Thanks to in-mold coating technology, all manufactured elements are resistant to UV as soon as they are removed from the mold (eliminating further spraying).

4, Customized techniques

To meet clients’ requirements and needs, we developed proprietary solutions that enable manufacture of unique products. For many years we built our reputation as a supplier who provides solutions where others failed.

We also offer expertise in microsphere and bladder inflation.
