The Process
Wet winding, under CNC control
Raw fibre rovings pass through a resin bath and are laid onto a rotating mandrel by a CNC-controlled carriage. The machine coordinates mandrel rotation and carriage travel to place fibre at precise, repeatable angles.
We wet-wind rather than use pre-impregnated towpreg, it gives us full control over resin chemistry and fibre-to-resin ratio, and produces a denser, better-consolidated laminate for structural and pressure parts.
The Differentiator
Wind angle is where the strength is engineered
The angle fibre is laid at, relative to the mandrel axis, dictates where the part is strong. We tune it per application, a distributor working from a catalogue simply cannot.
~30°
Low angle
High axial, compressive & tensile strength
Best for: Bending loads, columns, drive shafts
~85°
High angle
High burst / circumferential strength
Best for: Pressure vessels & cylinders
