SOLARIS

Open Weave Architecture · v1.0

SOLARIS is a fiber weave pattern designed to deliver multi-axis tensile strength on standard textile equipment. Material-agnostic by design, works with cellulose, synthetics, and high-performance yarns alike. Fully open under CERN-OHL-W 2.0. Anyone with a loom and yarn can weave it. Anyone can modify it. Anyone can build with it.

What it is

A zone-alternating bi-axial weave. Twill regions are interlocked with pearl-weave nodes, creating a virtual third axis of reinforcement on a standard 2-axis loom, without the cost or complexity of tri-axial weaving machinery.

Repeat unit: 12 warp × 12 weft

Why it works

Specification

Fiber
Any natural or synthetic yarn with adequate tensile strength. Cellulose-rich naturals (cotton, flax, jute, ramie, bamboo) work well. Synthetics (carbon, aramid, glass, UHMWPE) work for high-performance applications.
Yarn weight
Medium (Ne 10-20 equivalent). Lighter and heavier variants work.
Repeat unit
12 warp × 12 weft
Twill zone
4×4 region, 2/2 progression
Pearl node
2×2 region, plain weave
Loom requirement
Standard 2-axis. No special tooling.
License

How to start

If you run a textile workshop or have access to one, you can produce a SOLARIS sample in a single weaving day. Use any yarn you can source locally, the architecture is fiber-independent. Begin with a small swatch (40 × 40 cm) before scaling to bolt sizes.

Document what you do. Publish your results. The pattern grows with every replication.

What we ask in return

Nothing. SOLARIS is genuinely open. If you build something with it, tell us. We want to see what the world makes. If you improve it, share the improvement back. That's how an open architecture stays useful.

The land gave us the material. We're giving back the knowledge.
