Composite profiles (GRP, FRP)

Composite profiles are known under lots of names - GRP, FRP, CRP, glassfibre or carbonfibre profiles. We produce it by a pultrusion technique from resin and reinforcing elements. Polyester resin is applied as a matrix most frequently; epoxy, vinylester, acrylate and other resins are used for special applications. In most cases, glass fibres are used as reinforcement, but carbon or aramid fibres are applied too. Depending on the properties required, straight fibres (rovings), various types of mats or fabrics or their combination are chosen.   






 Advantages of composite profiles:

  • feature dimensional accuracy of the profile
  • high tensile strength
  • high impact strength
  • corrosion resistance
  • outstanding electroinsulating characteristics
  • low heat conductivity and heat expansion
  • specific weight
  • long service life
  • minimum maintenance

  

 Possible application

  • constructions elements in building industry
  • covering panels in busses, trams, trains
  • constructions elements in aircraft production
  • window frames or reinforcement of window frames
  • elements in chemical industry (corrosive environments including chemical premises)
  • edges on lorry box bodies
  • rods in heavy-current electrical industry (insulator supporting poles of high-voltage distribution systems, supporting members of trolley systems, spacing profiles in large transformers,...)
  • sport equipment (hockey sticks, arrows, bows, tents, )
  • ladders

   






    
5M produces standard pultrusion profiles, but also a lot of profiles tailored to customer requirements – profiles specific in shape for application in various industries.

 

NEW TECHNOLOGY - POLYURETHAN PULTRUDED PROFILES

As the leader in the field of composites, we are the first in Europe to introduce a composite pultrusion profile made from polyurethane. In comparison to common resins used in pultrusion, this composition has several unrivalled advantages. The combination of polyurethane and glass reinforcement we achieved excellent properties of the final composite profile!

Looking for material which is impact resistant? Which is lightweight, chemically resistant, has excellent strength and is easily machined? So the polyurethan pultrusion is the right solution for you!
