  • Optimal curing: controlled temperature ramp; post-cure may improve Tg and mechanical properties.
  • Tooling: molds must support complex curvature; release agents recommended to avoid adhesion.
  • Clean cuts require diamond or carbide tooling; dust control and PPE advised when machining fibers.
