types of fibres

  • Carbon

    has several advantages including high stiffness, high tensile strength, low weight, high chemical resistance, high temperature tolerance and low thermal expansion.

  • basalt

    Natural mineral sourced, has benefits such as good tensile strength, non-toxic, resistant to UV, impact resistant, high temperature tolerance (-260 - 700 °C) and more economic than carbon, Kevlar and glass fibres.

  • Flax

    Plant based locally sourced fibre, is a sustainable alternative in composites. Is biodegradable, cost with has good mechanical properties, high specific stiffness, easy processability, and low density.

  • Glass

    Glass made has comparable mechanical properties to other fibres such as polymers and carbon fibre.

MAIN UPGRADES

  • FIBRE LOAD CAPACITY

    4 bobbins max capacity to increase productivity approach and allow to increase significantly the section size to produce thicker and more load bearing structures.

  • bi component

    Supply system loaded on End Effector, allows for a higher and more precise level of control on the resin flow supply. As well an on-demand ration control allowing to change parameter values during the winding process.
