Composite Repair Cost at 110% share of repairs counted in this cost: a worked example

Push share of repairs counted in this cost up to 110% and the picture changes. This example computes every intermediate figure at that operating point. estimating rework or repair exposure for composite parts

The inputs for this scenario

  • Composite defects needing repair: 18 repairs (unchanged)
  • Labor and material cost per repair: 410 $ / repair (unchanged)
  • Share of repairs counted in this cost: 110 % (raised for this scenario; the documented default is 100)
  • Fixed repair setup and inspection cost: 650 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable composite repair cost = composite repairs required × repair cost per composite defect × repair scope included) to the inputs above produces each figure below.
  • At this operating point the engine returns 8,768 $ for total composite repair cost, the number this scenario is built around.
  • At this operating point the engine returns 487 $ / piece for composite repair cost per part or job.
  • At this operating point the engine returns 8,118 $ for variable composite repair cost.
  • At this operating point the engine returns 650 $ for fixed repair setup and quality cost.

How this compares with the baseline

  • Against the tool's baseline example, where share of repairs counted in this cost sits at 100% and the headline result is 8,030 $, this scenario comes in 9.19% above the baseline at 8,768 $.
  • It computes total composite repair cost by multiplying repairs by cost-per-repair, scaling by the share included, then adding fixed setup and quality cost. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • total composite repair cost: 8,768 $ (headline result)
  • composite repair cost per part or job: 487 $ / piece
  • variable composite repair cost: 8,118 $
  • fixed repair setup and quality cost: 650 $
