Applies Darcy’s law to vacuum infusion: fill time for a given flow length, the flow front velocity when it arrives, Darcy flux, and the longest flow path that will fill inside the resin’s working life.

Reduces a six-shot fair-fire series to a ballistic limit: V50 as the mean of the three highest partial and three lowest complete penetrations, the velocity spread against the acceptance limit, the zone of mixed results and the scatter of the series.

Resolves the three yarn sets of a triaxial weave onto any test direction: strength along the axial direction, at the test angle and across it, the isotropy ratio the construction achieves, and the allowable load after a safety factor.

Balances occupant kinetic energy against webbing stretch: the restraint force the elongation implies, the deceleration in g, how much of the webbing break load it consumes and the elongation actually needed to stay inside that load.

Converts fibreglass woven roving areal weight into cured ply thickness at a working fibre volume fraction, then plans the stack: plies for a target thickness, the laminate weight it builds and the resin it will draw.

Converts prepreg fibre areal weight and resin content by weight into prepreg areal weight, resin areal weight, fibre and resin volume fractions, cured ply thickness and laminate density.

Extrapolates canopy fabric permeability from the laboratory test differential to deployment pressure using a power law, giving the through-flow velocity, the multiplier over the certificate value and the total volumetric leakage across the canopy.
