GRP

NEW CUSTOM SOLUTIONS FOR VEHICLE BODY DESIGN  

Fiberglass reinforced plastic, abbreviated GRP, is a fiber-polymer composite made of a durosetting or thermosetting polymer and glass fibers. The glass fibers provide mechanical reinforcement, and the resulting resin is selected based on the intended application and final loa d. Thanks to the the fiberglass reinforcement, GRP material provides a high degree of mechanical strength and can withstand heavy loads. We are able to manufacture complex, three-dimensional GRP components which can be used in a wide arr ay of applications where traditional materials such as steel, stainless steel and aluminum reach their limits.

The finished components are dimensionally stable and boast exceptional strength. The high chemical, UV, and weather resistance of GRP prevents it from losing its shape, color or function. GRP also features thermal and electrical insulation properties as well as magnetic transparency and corrosion resistance and makes mounting quick and cost-effective thanks to its relatively low production cost and low weight.

We use tailored production processes to manufacture customized components where we arrange glass fibers in a specific orientation and specific thicknesses as required by the end application. As a company certified in adhesive bonding,, OWS has qualified employees and the technical expertise and facilities required to provide solutions as a GRP partner for any vehicle body components.


IN THE EVENT OF DAMAGE

Material damage usually results in an overall component failure. Due to the fiberglass structure, however, only a few individual fibers in the composite break in most cases. At OWS, our specially trained employees can repair this type of damage.

TYPES OF DAMAGE

  • Aging caused by UV light, water, cleaning products and mechanical stress, e.g., stress cracks
  • Damage to the paint layer caused by UV light and mechanical stress
  • Destruction of the plastic as well as the internal structure of the GRP caused by water penetration
  • Mechanical damage caused by external impact

RESULT

  • Complete destruction of the internal structure

PROTECTIVE MEASURES

  • Wall thicknesses are adapted according to the requirements of the final application.
  • Strength is tuned to specific impact stress.
  • Special fiberglass reinforcement is used.
  • An additional paint layer is applied.

COMPLETE / PARTIAL REPLACEMENT OF THE COMPONENT / ASSEMBLY

  • Material diagnostics, damage limitation via removal of the damaged area
  • Negative forming (mold and die department), even possible with previously-unknown components
  • Materials for new components selected by experts to ensure adherence to applicable fire protection requirements for rail vehicles
  • Production of the positive component for lamination in the demarcated area
  •
