Light-mode laminate ply editor, angle-colored live stack and ABD properties
01

Connected laminate workspace

A 16-ply laminate using a linked Micro recipe. The live stack is colored by ply angle, alongside the shared CLT properties.

Open full-size GUI ↗
Light-mode material comparison with eight records and colored Ashby groups
02

Materials and Ashby comparison

Eight selected reference records populate the comparison table and material-class plot. Sources and screening values must still be checked for design use.

Open full-size GUI ↗
Actual short-fiber GUI with orientation inputs and a spatially distributed fiber preview
03

Random short-fiber orientation

Cox shear-lag teaching setup with Fa = 0.15 and Fp = 0.35. The 3D illustration uses normalized fiber lengths; it is not a resolved RVE or a physical-scale micrograph.

Open full-size GUI ↗
Light-mode thick-laminate temperature field, heating history and through-thickness section
04

Thick-section thermal lag

A 64-mm, 16-layer teaching variation of the local T700 demo, with a heating-ramp cursor and through-thickness section. Conduction demonstration only: the GUI reports missing reaction-heating data. Not a NASA benchmark or a qualified cure cycle.

Light-mode T700S material record with supplier provenance and editable elastic properties
05

Source-aware material records

The T700S source panel distinguishes supplier data from editable CDS completion fields. Property groups, units and locks remain visible.

Light-mode Workbench carpet plot and colored laminate stack
06

Live design-space exploration

The light-mode carpet-plot workspace connects a design-space surface to the live laminate. This is an existing GUI capture, not a newly validated result.
