Cured Ply Thickness Calculator


This tool calculates the individual cured ply thickness in a laminate, given: the areal weight of the reinforcement fibres (in g/m2); the density of those fibres (in g/cm3); and the weight fraction and density of the matrix resin. (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.) The tool does not take into consideration any content of voids in the ply/laminate.

Reinforcement Density (g/cm3)
E-Glass 2.56
Carbon 1.75–1.95
Aramid (Kevlar 49) 1.45
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
