Pultruded FRP profiles are with the constant cross-section structure by a continuous pultrusion process using fiberglass reinforcements with thermosetting resin matrixes. Pre-selected reinforcement materials, such as fiberglass roving, mat, woven fabricsor
stitched fabric, are drawn through a resin bath in which all materials are thoroughly impregnated with a liquid thermosetting resin.
Typical resins included unsaturated polyester, vinyl esters,and epoxy.
Any constant cross-section profiles can be pultruded. Pultrusion allows the designer to customize the selection of the resin
system,the type and form of fiberglass reinforcements, and the placement of the reinforcements within the composite profile.
Typical pultruded profiles include FRP Angle, Square Tube, I Beam, Channel, Round Rod, Round Tube, T Beam, etc. They are
widely used as handrail, support, beam and other structure materials in the industries of chemical, power, infrastructure, etc.
HERE ARE SOME OTHER FEATURES:
- High strength
- Light weight
- Electrical and thermal insulation
- Flame retardant
- Electro-magnetic transparency
- Low coefficient of thermal expansion
- Low temperature capabilities
- Long working life,easy maintenance.
- Easy to cut and install.
- Free to design
The raw materials are pulled through a heated steel forming die using a continuous pulling device,FRP pultruded profile are
made of different resins reinforced with fiberglass by pultrusion technology.
