Composites, Fiberglass & Advanced Materials calculators

Lay it up, cure it and cost the laminate. Each calculator uses the numbers a composites shop already has and says whether the plan holds.

What this hub covers

  • Composites calculators for layup labor, fiber and resin usage, infusion and cure cycles, laminate thickness and fiber volume, bagging and tooling cost, inspection, defects and price variance.
  • Browse composites, fiberglass & advanced materials calculators for manufacturing planning, quoting, quality, capacity, and operations decisions.

Best calculators in this category

  • Composite Layup Labor: Hand layup labor hours from ply area and pace, plus the margin against a target the schedule sets.
  • Carbon Fiber Material Cost: Carbon fiber material spend from weight, purchase price and included scope, with freight added and cost per pound shown.
  • Fiberglass Resin Usage: Mixed resin pounds consumed and their cost over a lamination run, with cost per runtime hour.
  • Resin Infusion Time: Estimate vacuum infusion fill time from volume and stable flow, then compare it with the resin gel time.
  • Vacuum Bagging Cost: Vacuum bagging spend from bag area, consumable rate and applied scope, with the fixed vacuum test spread per square foot.
  • Autoclave Cycle Cost: Autoclave cost for a cure cycle from its hours and burdened rate, the chargeable share and the fixed setup cost.
  • Prepreg Scrap Cost: Prepreg scrap cost from the net scrapped weight, delivered cost, charge share and handling and disposal.
  • Cure Cycle Capacity: Oven hours the cure batches need, allowance included, checked against the cure window the schedule allows.
  • Composite Part Cost: Composite part cost at the lot size from direct cost, the included share and fixed tooling, checked against a target.
  • Laminate Thickness: Cured laminate thickness from ply count and cured ply thickness, with deviation, plies to target and the ply budget.
  • Fiber Volume Fraction: Fiber volume fraction from the two volumes of one cured sample, with matrix share and the gap to the target.
  • Resin Mix Ratio: Hardener weight and total batch for a supplier mix chart given in parts by weight.

Live market signals for this industry

  • The producer price index for plastic resins and materials stands at 276.296 (BLS, Sep 2026), up 6.5% from a year earlier. Quotes priced off last quarter's material cost miss this move.
  • Steel mill PPI stands at 388.58 (BLS, Sep 2026), up 27.6% from a year earlier. New factory orders are up 10.5% year over year (Census).

Category questions

  • Where do the default values come from? They are illustrative numbers for a typical job so the page shows a worked answer. Replace them with your own measurements, datasheets and quotes before you rely on a result.
  • Why do some results show a warning? A warning means the plan fails a limit you entered or one from a cited source, such as a cure window, a fiber volume target or an out-time limit. The message states the gap and what to change.
  • Can I download the calculation? Yes. Every calculator has an Excel workbook with live formulas that match the page, so you can check the math or reuse it in a quote.
  • Why is a result blank? An input is missing or outside its valid range, so there is no honest number to show. The message above the result names the input to fix.
