Composites, Fiberglass & Advanced Materials worked example

Fiber Volume Fraction with fiber volume in the cured laminate of 1.4 cu in: a worked example in composites, fiberglass & advanced materials

Push fiber volume in the cured laminate up to 1.4 cu in and the picture changes. This example computes every intermediate figure at that operating point. checking fiber volume fraction against laminate specification

The inputs for this scenario

  • Fiber volume in the cured laminate: 1.4 cu in (raised for this scenario; the documented default is 0.56)
  • Total cured laminate volume: 1 cu in (unchanged)
  • Percent reporting conversion: 100 x (unchanged)

Working through the calculation

  • Applying the documented formula (Fiber Volume Fraction = fiber volume in the laminate รท total cured laminate volume) to the inputs above produces each figure below.
  • At this operating point the engine returns 140 x for fiber volume fraction, the number this scenario is built around.
  • At this operating point the engine returns 1.4 value for raw ratio.
  • At this operating point the engine returns 100 x for conversion factor.
  • At this operating point the engine returns 1 value for total cured laminate volume.

How this compares with the baseline

  • Against the tool's baseline example, where fiber volume in the cured laminate sits at 0.56 cu in and the headline result is 56 x, this scenario comes in 150% above the baseline at 140 x.
  • It divides the fiber volume by the total cured laminate volume and converts the ratio to a percentage, giving the fiber volume fraction. 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.
