Book Description
There is a wealth of literature on modeling and simulation of polymer composite manufacturing processes. However, existing books neglect to provide a systematic explanation of how to formulate and apply science-based models in polymer composite manufacturing processes. Process Modeling in Composites Manufacturing, Second Edition provides tangible methods to optimize this process — and it remains a proven, powerful introduction to the basic principles of fluid mechanics and heat transfer. Includes tools to develop an experience base to aid in modeling a composite manufacturing process Building on past developments, this new book updates the previous edition’s coverage of process physics and the state of modeling in the field. Exploring research derived from experience, intuition, and trial and error, the authors illustrate a state-of-the-art understanding of mass, momentum, and energy transfer during composites processing. They introduce computer-based solutions using MATLAB® code and flow simulation-based analysis, which complement closed-form solutions discussed in the book, to help readers understand the role of different material, geometric, and process parameters. This self-contained primer provides an introduction to modeling of composite manufacturing processes for anyone working in material science and engineering, industrial, mechanical, and chemical engineering. It introduces a scientific basis for manufacturing, using solved example problems which employ calculations provided in the book. End-of-chapter questions and problems and fill in the blanks sections reinforce the content in order to develop the experience base of the manufacturing, materials, and design engineer or scientists, as well as seniors and first-year graduate students.

Book Description
Liquid Composite Molding (LCM) processes encompass a large family of composite processing methods that use a pressure difference to drive a liquid resin into a mold to saturate all the empty spaces between fibers of a stationary preform. The success in such net shape manufacturing processes is strongly correlated with the part geometry and design. Coupling LCM processing simulation tools with part design could make the manufacturing of composites more efficient. The aim of this dissertation is to present models, methodologies and frameworks to integrate the composite process simulation within the composite part design cycle. ☐ To bridge the gap between the composite process simulations with the part design, one needs to first automate the processing parameters’ selection and optimization in mold filling simulation packages. Various effective optimizers are developed to find the optimal injection/infusion scheme so that the results returned by the mold filling simulation packages can guide the part design process. ☐ Next, approaches are developed to improve the LCM simulation workflows by combining stochastic models and frameworks with the simulation engine to address possible variability in the process. Such improved simulation methodologies will provide useful feedback to the designer on how to reduce variability in the manufacturing process within the design workspace. ☐ To increase the efficiency of the design-simulation iteration cycle, a fast distance based model is developed to replace time intensive finite element based LCM simulation which makes it possible to provide qualitatively accurate information about the process to part designers in a very short period of time for them to modify the design to accommodate robust processing. This tool is shown to be useful in the initial stages of design when large number of permutations are inevitable. ☐ The methodology and integration framework is exercised to provide general design coupled with simulations solutions for manufacturing of net shaped composite parts and demonstrated with an application that couples the design with optimized process models that account for variability to achieve specific objective such as in wind blade design and manufacturing.

Book Description
The Resin Transfer Molding (RTM) process has gained popularity amongst composite manufacturers due to the surface quality and dimensional tolerances that can be achieved from this process. In this process, fiber preforms are placed in a rigid mold and resin is injected through a gate to fill the empty spaces between the fibers. Being a closed mold process, one cannot view the progression of flow during the filling stage. It has been commonplace that parts would contain regions unsaturated by resin. Not only would these parts have to be discarded, there was no knowledge as to how these unsaturated regions formed, and what to do to prevent repeat occurrence. Typically, a trial and error process is employed to attempt to correct for the problem. By modeling the RTM process as flow through anisotropic porous media, one can simulate and predict the flow in the mold if the permeability of the fiber is known. However, during the preform preparation or handling the permeability along mold edges varies from one point to the next. It was discovered that disturbances inside the mold led to alterations in the flow progression. The approach taken in this dissertation will be to manipulate the flow progression by selectively opening and closing gates during the filling process. The goal of the manipulation is to direct the flow in such a manner that despite the disturbances, one will be able to completely saturate the fibers with resin. The variation in flow progression is investigated and characterized using simulations. The fundamentals of flow manipulation are described with an introductory example. The true approach. A study quantifies the disturbance range and frequency in common manufacturing practice. With the nature of the disturbances better understood, several flow manipulation approaches were developed and compared. These approaches proved to be successful in the virtual manufacturing domain, but required experimental validation. Therefore, an experimental workstation was designed and built to accommodate the needs of the approaches. The workstation was used, and demonstrated the strengths and weaknesses of the various approaches.

Book Description
Polymer matrix composites are used extensively across a wide range of industries, making the design and development of effective manufacturing processes of great importance. Manufacturing techniques for polymer matrix composites (PMCs) provides an authoritative review of the different technologies employed in the manufacture of this class of composite.Following an introduction to composites and manufacturing processes, part one reviews the manufacturing of short fiber and nanoparticle based polymer matrix composites, with injection and compression molding examined in depth. Thermoplastic processing is the focus of part two. Sheet forming, fabric thermostamping, filament winding and continuous fiber reinforced profiles are investigated. Part three reviews thermoset processing. A survey of resin transfer molding follows, including vacuum-assisted and compression resin transfer molding. The pultrusion process is then considered, before the book concludes with an investigation into autoclave and out-of-autoclave curing processes in polymer matrix composites.With its distinguished editors and international team of expert contributors, Manufacturing techniques for polymer matrix composites (PMCs) is an essential guide for engineers and scientists working in the field of polymer matrix composites. - Provides an authoritative review of the different technologies employed in the manufacture of polymer matrix composites - Reviews the manufacturing of short fiber and nanoparticle-based polymer matrix composites, with injection and compression molding examined in depth - Examines thermoplastic processing, sheet forming, fabric thermostamping, filament winding and continuous fiber reinforced profiles
