Steered fibre paths raise buckling load of stiffened composite panel in simulation
Source: SAGE Publications (Journal of Reinforced Plastics and Composites), "Investigation on buckling resistance of the stringer-panel structure with variable stiff laminate", published 6 November 2026.
What the source says
Numerical study of a stringer-stiffened composite panel with a 22-ply skin, steering fibre paths in two mid-plane plies by automated fibre placement. Buckling analysis showed first buckling load up 12.5%, or 18.2% with a polynomial path, with no added mass.
Allbase view
Steering fibres in a stiffened panel raised its buckling resistance, but only in a computer model; no panel was built or tested. Nothing to act on yet, even for aerospace laminates made by automated fibre placement.
