Pultrusion & Continuous Composite Profiles worked example

Resin Gel Time Margin with available resin gel time in the die of 310 units: a worked example

Push available resin gel time in the die up to 310 units and the picture changes. This example computes every intermediate figure at that operating point. Use it when resin gel time margin in pultrusion and continuous composite profiles needs a clean margin number for a pultrusion and continuous composite profiles go / no-go review.

The inputs for this scenario

  • Available resin gel time in the die: 310 units (raised for this scenario; the documented default is 125)
  • Required gel time for full cure: 100 units (unchanged)
  • Reference gel time for percent basis: 100 units (unchanged)

Working through the calculation

  • Applying the documented formula (Resin Gel Time Margin margin = available value - required value) to the inputs above produces each figure below.
  • At this operating point the engine returns 210 hr for absolute margin, the number this scenario is built around.
  • At this operating point the engine returns 210 % for margin.
  • At this operating point the engine returns 310 value for available amount.
  • At this operating point the engine returns 100 value for required amount.

How this compares with the baseline

  • Against the tool's baseline example, where available resin gel time in the die sits at 125 units and the headline result is 25 hr, this scenario comes in 740% above the baseline at 210 hr.
  • It subtracts required gel time from available gel time for an absolute margin, then divides by a reference value for a percent margin. 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

  • Absolute margin: 210 hr (headline result)
  • Margin: 210 %
  • Available amount: 310 value
  • Required amount: 100 value
