carbon fiber laminate block weight calculator
Enter the dimensions of a carbon fiber laminate block and this works out its volume and weight. Cured epoxy laminate at roughly 60% fibre volume fraction.
- Weight of one block
- 32
- Volume of one piece
- 20 000
- Density used
- 1600 kg/m3
Show the working
- Length = 1000
- Width = 200
- Height = 100
- Number of pieces = 1
- volume_mm3 = 1000 * 200 * 100 = 20 000 000
- Volume of one piece = 20 000 000 / 1000 = 20 000
- Density used = 1600 = 1600
- Weight of one block = 20 000 000 * 1600 / 1e9 = 32
- Total weight = 32 * 1 = 32
Values are shown to six significant figures here; the arithmetic itself runs on exact fractions and is only rounded where a number is printed.

The formula
- Volume = length x width x height
- Weight = volume x density, with density = 1600 kg/m3
- One cubic millimetre of a material at 1000 kg/m3 weighs exactly one milligram, so the millimetre-to-kilogram step is a shift of the decimal point rather than a rounded factor.
Cured epoxy laminate at roughly 60% fibre volume fraction.
Dimensions are nominal. Mill tolerances on thickness, and the corner radii on formed sections, both move the real weight by a percent or two.
Every field takes inches or feet as readily as millimetres: change the unit next to it and the conversion is done exactly before the arithmetic starts.
Frequently asked
What is the density of carbon fiber laminate?
1600 kg/m3, which is 1.600 g/cm3. Cured epoxy laminate at roughly 60% fibre volume fraction.
How do you calculate the weight of a carbon fiber laminate block?
Volume = length x width x height. Multiply the volume by the density of carbon fiber laminate, 1600 kg/m3, taking care that both are in the same unit system.
Can I enter dimensions in inches?
Yes. Each dimension field has its own unit selector, and inch, foot, millimetre, centimetre and metre entries are all converted exactly before anything is multiplied.
Where the numbers come from
- Densities are nominal room-temperature values for the grade named, drawn from the usual mill and handbook figures.
