Pultrusion & Continuous Composite Profiles worked example

Profile Weight Per Foot with profile cross-sectional area of 250 in²: a worked example

Push profile cross-sectional area up to 250 in² and the picture changes. This example computes every intermediate figure at that operating point. Use it when profile weight per foot in pultrusion and continuous composite profiles needs a few factors combined into one defensible number for pultrusion and continuous composite profiles.

The inputs for this scenario

  • Profile cross-sectional area: 250 in² (raised for this scenario; the documented default is 100)
  • Composite laminate density: 4 lb/in³ (unchanged)
  • Inches-to-feet length factor: 0.01 x (unchanged)
  • Void/resin-richness correction: 1 x (unchanged)

Working through the calculation

  • Applying the documented formula (Profile Weight Per Foot = first factor × second factor × conversion factor × process multiplier) to the inputs above produces each figure below.
  • At this operating point the engine returns 5 lb for result, the number this scenario is built around.
  • At this operating point the engine returns 5 value for base product.
  • At this operating point the engine returns 1 x for multiplier.
  • At this operating point the engine returns 1,000 value for factor a x b.

How this compares with the baseline

  • Against the tool's baseline example, where profile cross-sectional area sits at 100 in² and the headline result is 2 lb, this scenario comes in 150% above the baseline at 5 lb.
  • It computes the weight of one running foot of a pultruded profile from its cross-sectional area, the cured composite density, and a length/units correction factor. 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

  • Result: 5 lb (headline result)
  • Base product: 5 value
  • Multiplier: 1 x
  • Factor A x B: 1,000 value
