A highly significant interaction between geometry and CCF inclusion was also identified ( p < 0.0001), demonstrating that the influence of fibre reinforcement on void formation differs according to geometric complexity.
A highly significant interaction between geometry and CCF inclusion was also identified ( p < 0.0001), demonstrating that the influence of fibre reinforcement on void formation differs according to geometric complexity.
The SRH analysis corroborated the primary findings, identifying significant main effects for both geometry ( p = 7.44 × 10−9) and CCF reinforcement ( p = 0.0161), as well as a main effect of sterilisation ( p = 0.00820); however, the geometry × CCF interaction only approached significance ( p = 0.0969), supporting the conclusion that geometry and fibre reinforcement are the dominant drivers of deviation.
Between geometries, non-standard samples with CCF deviated most, but the direct geometry-by-CCF interaction did not reach statistical significance after correction.
