We manufacture your part as a fully carbon composite monolith — meaningfully lighter and demonstrably stronger than conventional assembled metal parts. No fasteners. No secondary bonding. One grown structure.
Send us your existing CAD and load case, or your raw forces, moments, and the space the part must live in.
We solve the load path — every fiber oriented to the stress it will actually carry, not to what's easy to tool.
Continuous carbon fiber accretes onto a dissolvable mandrel, layer by layer. No joints form because none are added.
The part cures as one fully composite piece. The mandrel dissolves. What's left is hollow, monolithic, lighter, and stronger.
Every part is a fully carbon composite monolith. Fiber orientation is driven by finite-element output, not tooling convenience. The result is hollow, joint-free, lighter, and stronger than metal parts built the traditional way.
Rebuilt as a single spanwise carbon composite structure. Significant mass reduction, same interfaces.
Continuous fiber wraps the bearing bore directly. No fasteners in the load path. Stronger and lighter.
Hoop-optimized winding, hollow monolith, fully composite, built to your environmental spec.

Have an existing design? We'll rebuild it as a fully carbon composite monolith — lighter and stronger. Starting from scratch? Send us the loads — we'll do the topology.
