Pultruted Grating Process
Pultrusion is a continuous process using fiber reinforcements with thermosetting resin matrices.
Pre-selected reinforcement materials, such as fiberglass roving, mat, woven fabrics or stitched fabric, are drawn through a resin bath in which all material is thoroughly impregnated with a liquid thermosetting resin. Typical resins include polyester, vinyl ester and phenolics.
The wet-out fiber is formed to the desired geometric shape and pulled into a heated steel die.
Once inside the die, the resin cure is initiated by controlling precise elevated temperature. The laminate solidifies in the exact cavity shape of the die, as it is continuously pulled by the pultrusion machine. Most any constant cross-section part can be pultruded.
