Continuous fiber impregnation system

Certech recently acquired a continuous fiber strand impregnation system. Using a special W-shape geometry, the different microfibers of the strand are separated and impregnated with thermoplastic material, then reassembled in the end of the die. The quality of the impregnation depends, on the quantity of microfibers in a section of the strand and on the viscosity of the polymer.

The die can reach temperatures of 350 ° C and tensile forces of 500N can be applied. The fiber strand must be less than 5mm in diameter and at least be able to withstand the applied tensile force.

The fibers thus impregnated can be woven and then thermoformed to obtain thermoplastic parts reinforced with continuous fibers.
