Special Issue Information

Dear Colleagues,

Studying liquid processing during manufacturing of composite materials has been a focal area over the last few decades spanning around developing cutting-edge experimental techniques and numerical approaches. These efforts aim to reduce manufacturing-induced deficiencies, tailor mechanical, thermal, and physical properties across different length scales, and enhance overall structural performance.

The purpose of this Special Issue, ”Liquid Processing for Manufacturing of Composite Materials: Experimental Techniques and Numerical Modelling”, is to collect state-of-the-art studies focused on experimental methods, theoretical approaches, and numerical simulations as well as high-quality review papers related to liquid processing during manufacturing of composite materials. Interesting topics include (but not limited to) experimental methods of characterising porous media properties, resin impregnation mechanisms/modelling into fibrous porous media at different length scales, rheology and cure kinetics of polymers, and multiphysics modelling of liquid composite moulding. In addition, articles may cover modification and functionalisation of composites applied in transport and renewable energy industries.

Abstract
Fibre deformation (or shearing of yarns) can develop during the liquid moulding of composites due to injection pressures or polymerisation (cross-linking) reactions (e.g., chemical shrinkage). On that premise, this may also induce potential residual stress–strain, warpage, and design defects in the composite part. [...] Read more.
Fibre deformation (or shearing of yarns) can develop during the liquid moulding of composites due to injection pressures or polymerisation (cross-linking) reactions (e.g., chemical shrinkage). On that premise, this may also induce potential residual stress–strain, warpage, and design defects in the composite part. In this paper, a developed numerical framework is customised to analyse deformations and the residual stress–strain of fibre (at a micro-scale) and yarns (at a meso-scale) during a liquid composite moulding (LCM) process cycle (fill and cure stages). This is achieved by linking flow simulations (coupled filling–curing simulation) to a transient structural model using ANSYS software. This work develops advanced User-Defined Functions (UDFs) and User-Defined Scalers (UDSs) to enhance the commercial CFD code with extra models for chemorheology, cure kinetics, heat generation, and permeability. Such models will be hooked within the conservation equations in the thermo-chemo-flow model and hence reflected by the structural model. In doing so, the knowledge of permeability, polymerisation, rheology, and mechanical response can be digitally obtained for more coherent and optimised manufacturing processes of advanced composites.

The development of high-performance composites for mechanical energy dissipation during impact or explosive events is of vital importance for the safety of personnel and infrastructures. Solid–liquid composites are an emerging class of energy absorbers where a liquid-phase filler is seamlessly integrated into a solid matrix to enhance the impact resistance of the protection target. This innovative approach leverages the distinct properties of both phases and the unique interactions between them to achieve superior performance under high-impact conditions. This paper aims to review the liquid-phase materials used in solid–liquid composites, ranging from neat liquids to complex fluids, including liquid nanofoam and shear-thickening fluids, to provide an in-depth analysis of the fundamental physics underpinning the resulting solid–liquid composites, and to explore how their unique properties contribute to enhanced impact resistance and energy absorption. Furthermore, this paper evaluates the advantages and limitations of these solid–liquid composites and offers insights into future directions for the development of solid–liquid composites in various fields, including personal protective equipment, automotive safety systems, and structural protection.
