1.Core Advantages - Three Precision Logics
Modulus and CTE,tuned together.
High-modulus plies bring the in-plane CTE toward near-zero - a panel that stays the same size while it warms and cools.
Stable under thermal cycling.
Quasi-isotropic high-modulus layups reach CTE around ±0.5*10⁻⁶/°C - where aluminum moves an order of magnitude more.
Finished to your datum.
Machine-finished faces and edges give you a ready reference surface - flatness and tolerance at the part,not the sheet.
2.Customization - Match the Tolerance
- Layup tuned to your CTE target.
- Grade by modulus and stiffness need.
- Size and thickness to your stage or fixture.
- Machined features - datum faces,holes,mounting pattern.

4.FAQ
Q:What makes the plate dimensionally stable?
High-modulus plies in a quasi-isotropic layup bring the in-plane CTE near zero.
Q:How low is the CTE?
Typical CFRP tooling:0.2-1.0 × 10⁻⁶/°C;optical-grade quasi-isotropic layups around ±0.5 × 10⁻⁶/°C.
Q:Why not use aluminum?
Aluminum expands far more per degree -a precision rig built on carbon keeps its geometry across temperature.
Q:Do you machine to my datum?
Yes - datum faces,holes and mounting patterns to your drawing.
