Carbon Fiber Material Cost at 69% carbon fiber scope included: a worked example

This worked example runs the carbon fiber material cost numbers for a tougher week than the baseline: 69% carbon fiber scope included instead of the typical 96%. Estimate carbon fiber material cost for prepreg, dry carbon fabric, tow, tape, or woven reinforcement.

The inputs for this scenario

  • carbon fiber material required: 185 lb (held at the documented default)
  • carbon fiber purchase cost: 68 $ / lb (held at the documented default)
  • carbon fiber scope included: 69 % (the input this scenario stresses; the baseline uses 96)
  • carbon material freight, qualification, and handling adder: 750 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Variable carbon fiber material cost = carbon fiber material required × carbon fiber purchase cost × carbon fiber scope included.
  • total carbon fiber material cost works out to 9,430 $ at these inputs, and this is the headline figure for the scenario.
  • carbon fiber material cost per part or job works out to 50.97 $ / piece at these inputs.
  • variable carbon fiber material cost works out to 8,680 $ at these inputs.
  • carbon material freight, qualification, and handling adder works out to 750 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where carbon fiber scope included sits at 96% and the headline result is 12,827 $, this scenario comes in 26.48% below the baseline at 9,430 $.
  • Use it when quoting a composite part, building a layup standard cost, or quantifying how scrap and buy-to-fly ratio affect material spend. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • total carbon fiber material cost: 9,430 $ (headline result)
  • carbon fiber material cost per part or job: 50.97 $ / piece
  • variable carbon fiber material cost: 8,680 $
  • carbon material freight, qualification, and handling adder: 750 $
