Composite Material Quantity Calculator

Preliminary estimates for dry fabric, prepreg, resin and roll consumption for flat or nearly flat laminates.

1. Define laminate
Geometry and stack
Supports / or ,, brackets, s symmetry and repeats like 0x2.

2. Material and allowances
Weight basis and losses
Resin is calculated from the dry fibre weight using the declared total-weight fraction.


Default orientation cutting allowances

Actual cutting waste depends on roll width, nesting, fabric architecture, backing paper, equipment and production planning.

3. Roll and cutting preview

Approximate preliminary estimate. Results must be independently verified before purchasing material, preparing cutting plans or beginning manufacturing. This tool is intended for flat or nearly flat laminates and does not replace CAD nesting, ply-kit development, manufacturing trials or production planning.
