Inside our composite shop: from mould to monocoque

How we lay up carbon fibre and Kevlar airframes in-house with zero outsourced tooling.

Inside our composite shop: from mould to monocoque

Mastering Aerostructures from Scratch

Lightweighting without sacrificing structural stiffness is the holy grail of high-end unmanned aviation. At Sarus Aerospace, we made an early strategic decision: we would not purchase off-the-shelf airframes.

In-House Tooling and Autoclave Processing

Our composite manufacturing division is equipped with high-precision CNC mould pattern milling, vacuum bagging setups, and controlled curing ovens. This allows us to rapidly iterate wing profiles, optimize spar thickness, and integrate wiring channels directly into internal carbon ribs.

By controlling the resin-to-fiber ratio and utilizing bidirectional aerospace carbon fabric interleaved with Kevlar impact skins, we achieve maximum impact resilience while shaving critical grams from the MTOW (Maximum Takeoff Weight).
