Fibre path defects are detrimental to the structural integrity of composite components and need be minimised through process optimization. This requires understanding uncured pre-preg material, which is influenced by multiple parameters, sophisticated multi-scale modelling tools. Even though capabilities techniques have been improved over past decades, occurrence localised wrinkles remains challenging predict. One processes known influence formation fibre consolidation laminates manufactured...
A stochastic multi-objective cure optimisation methodology is developed in this work and applied to the case of thick epoxy/carbon fibre laminates. The takes into account uncertainty process parameters boundary conditions minimises mean values standard deviations time temperature overshoot. Kriging utilised construct a surrogate model substituting Finite Element (FE) simulation for computational efficiency reasons. coupled with Monte Carlo integrated framework based on Genetic Algorithms....
A stochastic cure simulation methodology is developed and implemented to investigate the influence of kinetics uncertainty due different initial resin state on process cure. The addresses heat transfer effects allows quantification in temperature overshoot during Differential Scanning Calorimetry was used characterise variability a commercial epoxy aerospace applications. It found that associated with variations degree cure, activation energy reaction order. model coupled conventional Monte...
Thermochemical properties are needed to develop process models and define suitable cure cycles convert thermosetting polymers into rigid glassy materials. Uncertainty surrounding the suitability of thermal analysis techniques semi-empirical developed for conventional composite materials has been raised new class particle interleaf This paper describes kinetics, conductivity, heat capacity glass transition temperature measurements HexPly® M21 material.

A stochastic cure simulation approach is developed and implemented to investigate the influence of fibre misalignment on cure. Image analysis used characterize fiber in a carbon non‐crimp fabric. It found that variability tow orientation significant with standard deviation 1.2°. The autocorrelation structure modeled using Ornstein‐Uhlenbeck sheet problem addressed by coupling finite element model Monte Carlo scheme. Simulation an angle shaped fiber‐epoxy component shows can cause...
