Cured Ply Thickness Calculator
This tool calculates the individual cured ply thickness in a laminate, given: the areal weight of the reinforcement fibres (g/m2); the density of those fibres (g/cm3); and the weight fraction and density of the matrix resin. The tool does not take into consideration any content of voids in the ply/laminate.
A second calculator is provided to convert volume fraction of fibres to weight fraction of resin – this uses the same weight and density data entered into the ply-thickness calculator.
| Reinforcement | Density (g/cm3) |
|---|---|
| E-Glass | 2.56 |
| Carbon | 1.75–1.95 |
| Aramid (Kevlar 49) | 1.45 |
| Flax | 1.4 |
| Resin | Density (g/cm3) |
|---|---|
| Epoxy | 1.1–1.4 |
| Polyester | 1.2–1.5 |
| Polyamide (Nylon 6.6) | 1.14 |
| Polypropylene | 0.9 |
| PEEK | 1.26–1.32 |
