Simulation & FEM material data
How to use it: pick a fibre and a resin (required), optionally a fabric weave and a manufacturing process, then hit Calculate. You get the properties of the whole laminate as if it were a single solid material, plus downloads ready to paste into Abaqus, LS-DYNA or ANSYS.
How it's calculated: fibre + resin properties are combined with standard micromechanics (Chamis 1984) into a single "UD" ply, the fabric and process then knock those numbers down for real-world imperfections, and the ply stack you build is solved with Classical Lamination Theory (full 3×3 stiffness matrix, so off-axis and unbalanced stacks are handled correctly, not just symmetric ones). Everything is a generic, literature-based estimate for preliminary design -- always verify against coupon or process test data before final use.
Constituent-to-laminate calculator
1. Choose your fibre and resin
2. Fabric & manufacturing (optional)
Selecting a manufacturing process fills Vf with its nominal value; edit it manually at any time.
3. Build the laminate
Pick a common layup family for an instant "homogenized" laminate reading, or switch to Custom to edit each ply by hand. Symmetric families are mirrored automatically (bottom-to-top).
| Ply | Angle [deg] | Thickness [mm] |

Output
These are the properties of the whole laminate, as if it were a single solid material. "Quasi-isotropic" means it behaves the same in every in-plane direction, like a metal sheet would.
A: extensional stiffness [N/mm]. B: extension-bending coupling [N]. D: bending stiffness [N·mm]. eta_x,xy / eta_y,xy: shear-extension coupling coefficients (Jones, Mechanics of Composite Materials) -- zero for a balanced laminate.
Hashin (above) only flags when damage starts. These control how the material actually degrades afterwards (fracture energy) and whether plies separate (delamination). Values marked default are generic literature estimates, not measured for this specific fibre/resin -- enter real data in the admin if you have it.

Downloads use the currently selected fibre, resin, fabric, process, Vf and ply stack (SI units regardless of the display toggle above). Calculate first so the ply/laminate exports reflect the latest inputs. JSON exports include full constituent source data, the UD/ply/laminate properties and the ABD matrix; Abaqus/LS-DYNA/ANSYS cards include elastic constants, thermal expansion and ply strength allowables.
