The project provides a comprehensive physical understanding on thermal de-consolidation and re-consolidation processes in advanced thermoplastic composites during re-heating/cooling processes, such as thermoforming and joining. Mechanistic models based on theoretical analysis, experimental studies and computational modelling will be established to provide a unified approach to predict de-consolidation and re-consolidation processes. Optimum processing-windows will be established, with which the undesired deterioration in material meso-structures and mechanical performance due to de-consolidation is effectively minimised. The outcomes of the project will fill the gap in the knowledge for thermoplastic composite processing and will improve the integrity of thermoplastic composite structures in practical applications.Read moreRead less

A Novel Approach to Determine Permeability for Cost-Effective Manufacturing of Thermoplastic Matrix Composites. The permeability (resistance of a porous rigid body to a permeating fluid) is an essential parameter for predicting impregnation quality in processing of thermoplastic composite materials. No reliable method exists yet to estimate permeabilities without time-consuming and cost intensive experiments. The aim of the proposed research project is to obtain a basic knowledge in determining ....A Novel Approach to Determine Permeability for Cost-Effective Manufacturing of Thermoplastic Matrix Composites. The permeability (resistance of a porous rigid body to a permeating fluid) is an essential parameter for predicting impregnation quality in processing of thermoplastic composite materials. No reliable method exists yet to estimate permeabilities without time-consuming and cost intensive experiments. The aim of the proposed research project is to obtain a basic knowledge in determining permeabilities of fibre architectures by taking into account their stochastic properties. An innovative approach, based on characterisations of meso-structures of fibre network and simulation of computational fluid dynamics, will be developed to accurately determine permeabilities. The outcome will enable more cost-effective manufacturing of thermoplastic matrix composites.Read moreRead less
