Out-of-autoclave prepregs produce low-porosity parts through a complex consolidation process that includes air evacuation through a partially impregnated microstructure and subsequent resin infiltration flow. In this article, we propose, develop, and validate the first model describing this consolidation process by computing the thickness change of the material during processing. The air evacuation period is first simulated as a function of fiber packing and pressure conditions. Then, the cure… Expand
Air evacuation and resin impregnation in semi-pregs: effects of feature dimensions
Abstract Prepregs with discontinuous resin (semi-pregs) impart robustness to vacuum-bag-only processing of composites. Limited guidance exists for evaluating advantageous resin patterns (i.e. dryExpand
Consolidation Modeling during Thermoforming of Thermoplastic Composite Prepregs
To reveal the evolution of the consolidation level, which reflects the number of voids in the composite, an intimate contact model was used during the thermoforming process and was implemented into a recently developed prismatic solid-shell finite element. Expand
A continuum approach for consolidation modeling in composites processing
Abstract During composite processing, consolidation refers to the application of pressure and/or temperature cycle to the fiber preforms and the uncured liquid resin to increase the fiber volumeExpand
An experimental technique to characterize interply void formation in unidirectional prepregs
Out-of-autoclave prepreg processing requires evacuation of volatiles in the early stages of processing to achieve an acceptable final void content. In this study, single prepreg plies were laid-upExpand
In situ monitoring and analysis of void evolution in unidirectional prepreg
In the layup of prepreg laminates, air is inevitably entrapped between adjacent prepreg plies, yet the removal of this inter-ply air under vacuum bag cure conditions is not well understood. In thisExpand
Gas Evacuation from Partially Saturated Woven Fiber Laminates
Gas evacuation from a partially saturated composite prepregs—a woven fabric reinforcement with a laminated liquid resin film—was characterized using the pulse-decay method. Dimensionless analysis wasExpand
Experimental and numerical study of coupled gas and resin transport and its effect on porosity
Partially-impregnated prepregs are three-phase systems consisting of fiber, resin, and gas. During processing, one of the main goals is to evacuate the gas and infiltrate the space left behind withExpand
Effects of thermal gradients on defect formation during the consolidation of partially impregnated prepregs
We describe the effects of thermal gradients on the consolidation of partially impregnated prepregs. Laminates were cured on a heated tool in isothermal and nonisothermal conditions. Key processExpand
Bulk factor characterization of heated debulked autoclave and out-of-autoclave carbon fibre prepregs
Abstract Tow impregnation during cure causes change in the laminate thickness, thus bulk factor, which causes variation in prepreg air permeability and large thickness deviations around corners. AExpand
Mechanisms of inter‐ply void formation during vacuum bag‐only cure of woven prepregs
The removal of inter-ply air is critical for limiting porosity in laminates. In this study, an in situ monitoring technique was employed to observe inter-ply air evolution during vacuum bag-onlyExpand


Out-of-autoclave prepreg consolidation under deficient pressure conditions
The present study investigated the effects of three pressure-related process deviations (reduced ambient pressure, reduced vacuum and restricted air evacuation) on the consolidation and quality ofExpand
Measuring the impregnation of an out-of-autoclave prepreg by micro-CT
Resin flow into dry reinforcement regions is the main microstructural change during the processing of out-of-autoclave prepregs and influences air evacuation and void suppression. Such impregnationExpand
