calibrated fibres materials
-
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.
-
New Fibre
We can also adapt and calibrate our process and equipment to any fibre you are currently using or you are interested in. Reach out to us for more information.
