Carbon Fiber Panels
Steps:
Find density (kg/m^3) or mass per area (kg/m^2) of prepreg used for manufacturing
Find total volume (m^3) or total surface area (m^2) of carbon fiber panels
Calculate mass (kg) of carbon fiber panels
Step 1 - Density of Material
Material is primarily woven carbon fiber prepreg.
Note: GSM stands for gram per square metre.

Thermoformed Panels
Steps:
Find density (kg/m^3) or mass per area (kg/m^2) of thermoformed panel used for manufacturing
Find total volume (m^3) or total surface area (m^2) of carbon fiber panels
Calculate mass (kg) of carbon fiber panels
Step 1 - Density of Material
Material is polycarbonate or PET G. Calculates will use density of PET G because it is heavier.
Material | Density | Source |
|---|---|---|
PET G | 1.23 g/cm^3 | Ultimate 3D Printing Material Properties Table (simplify3d.com) |
Polycarbonate | 1.22 g/cm^3 | Polycarbonate (PC) Plastic: Properties, Uses, & Structure - Guide (specialchem.com) |
Step 2 + 3 - Total surface area and Mass
Panel | SA (m^2) | Mass (SA x 1.23 x 1/8 inch thickness) (kg) |
