Fibre composite technology Carbon
CFRP/GRP/NFRP/AFRP

Extremely light-weight, rigid and simplicity of form are only some of the attributes that long fibre-reinforced plastics are known for and have an excellent future in automotive manufacturing as well as in other industrial sectors.

Specialisation

As specialists in processing of fibre-reinforced composites, we have lots of experience in the commercially used processing techniques for long and continuous fibre-reinforced plastics such as in pre-preg-autoclave technology, fibre winding technology and the fibre sprays. We realized the potential of the RTM-Technology at a very early stage and concentrated and specialized in this process.

Since 1999, we have been exploiting the advantages of this technology, including reproducibility, high surface quality, mapping complex geometries, economical serial production and we were able to successfully complete many projects during this period.

CFRP

CFRP generally stands for "carbon fiber reinforced plastic" (also "carbon fiber-reinforced plastic"). CFRP is a fiber-reinforced composite material in which carbon fibers are embedded in a resin matrix (e.g., epoxy resin).

Properties

  • Very high strength

  • Extremely lightweight

  • Stiff

  • Very high stiffness

  • Electrically conductive

  • Good radiolucency (e.g., X-rays)

Typical applications

  • Aerospace

  • Motorsports

  • Automotive industry

  • Shipbuilding and shipbuilding industry

  • Yacht building Sports and leisure (golf clubs, fishing rods, bicycle frames)

  • High-end components in mechanical engineering

GRP

GRP stands for "glass fiber reinforced plastic." It is a composite material in which glass fibers are embedded in a polymer matrix (usually polyester, vinyl ester, or epoxy resin).

Properties

  • High strength properties, comparable to those of aluminum alloys

  • Relatively lightweight, but heavier than CFRP

  • More cost-effective than CFRP

  • Electrically insulating

  • Good chemical resistance

  • Good weather resistance

Typical applications

  • Boat hulls

  • Car bodies and motorhomes

  • Tanks and pipes

  • Machine cladding

  • Wind turbines (sometimes in combination with other fibers)

NFRP

NFRP stands for "natural fiber reinforced plastic." NFRP is a composite material in which natural fibers serve as reinforcement, e.g., flax, hemp, jute, sisal, or wood fibers. These fibers are embedded in a plastic matrix (usually PP, PE, or biopolymers).

Properties

  • Eco-friendly (renewable raw materials)

  • Good stiffness properties

  • Good damping and acoustic properties

  • However, lower strength and moisture resistance than CFRP/GFRP

  • Moderate strength properties

  • High moisture absorption

Typical applications

  • Interior trim in cars (door panels, dashboard components)

  • Furniture

  • Lightweight housings and consumer goods

  • Sports and leisure products

  • Building materials (e.g., wood fiber-reinforced plastics)

AFRP

AFRP stands for aramid fiber reinforced plastic. An AFRP consists of: Aramid fibers (e.g., Kevlar, Twaron) provide strength, toughness, and protection. A polymer matrix (e.g., epoxy resin) holds the fibers together.

Properties

  • Extremely impact-resistant – higher than CFRP/GFRP

  • Very lightweight

  • Non-conductive

  • High abrasion resistance

  • High heat and fire resistance

  • Good energy absorption (ideal for protective systems)

  • However, less stiff than CFRP

  • UV-sensitive (requires a protective coating)

Typical Applications

  • Aramid fiber-reinforced plastics are often used where protection, toughness, and low weight are important:

  • Protective vests, helmets, ballistic plates

  • Motorsport & aerospace (parts subject to high impact loads)

  • Sports equipment (paddles, tennis rackets, skis)

  • Ropes, straps, parachutes

  • Impact-resistant housings

  • Composite components with high energy absorption requirements
