Bent elements
CNC bent
Stirrups and shaped elements, cut and bent to drawing. Different economics from straight bar, usually better.

What is in the line
01CreelRoving feeds from the back of the line. How evenly it feeds decides whether the bar has a consistent section.
02Pre-heat and plasmaRoving is dried and surface-activated before it meets resin. Bond between fibre and matrix is won or lost here.
03Three-stage impregnationResin introduced in stages rather than one bath. Dry fibre inside a bar is a void, and voids are where attack starts.
04Wrap and surfaceHelical wrap and sand coating applied before cure. Retrofitting this later is expensive.
05SWIR curingShort-wave infrared passes through the glass and is absorbed by the resin, so the bar cures from the inside out.
06Two-stage coolingControlled air, then water. Cooling too fast locks stress into the bar.
07Caterpillar pullerGrips along a length rather than at points. This is what holds modulus where a roller puller does not.
08Cut or coilTo length, or wound. Cut length consistency is measured here.
