Description

Yonggang Xue and colleagues devise in 2026 a laminate trick that keeps curved satellite antenna ribs from warping as temperatures swing in orbit. Carbon-fibre ribs bend when heated because their arc turns in-plane expansion into out-of-plane lift, and standard theory mispredicts that expansion badly, causing errors up to 79.4 percent in symmetric designs. Their asymmetric stack uses nine plies on top and seven below from the same material batch, creating a deliberate expansion mismatch.

The mismatch generates a thermal moment that fights the curvature-driven lift directly. Against the symmetric design, thermal deformation fell by 50.4 percent, from 210 to 104 micrometres, in the tests reported. Prediction accuracy improved to under five percent error, and the method needs only ordinary materials and processing.
