Book Synopsis Flow Molding of Discontinuous Fiber Reinforced Plastics by : L. A. Goettler

Download or read book Flow Molding of Discontinuous Fiber Reinforced Plastics written by L. A. Goettler. This book was released on 1969. Available in PDF, EPUB and Kindle. Book excerpt: The report presents a literature survey which covers aspects of molding and rheology pertinent to the flow molding of plastics containing elongated fillers, e.g. fibers or whiskers. Emphasis is placed on filler orientation, flow behavior, and breakage. The molding literature does not present a scientific approach to the investigation of these phenomena, and reported observations are not quantitative and are not interpreted in the light of current rehological developments. A specific program is recommended for the study of fiber orientation and placement in the molding of simple shapes. (Author).

Book Synopsis Fiber-dependent injection molding simulation of discontinuous reinforced polymers by : Wittemann, Florian

Download or read book Fiber-dependent injection molding simulation of discontinuous reinforced polymers written by Wittemann, Florian. This book was released on 2022-11-18. Available in PDF, EPUB and Kindle. Book excerpt: This work presents novel simulation techniques for injection molding of fiber reinforced polymers. These include approaches for anisotropic flow modeling, hydrodynamic forces from fluid on fibers, contact forces between fibers, a novel fiber breakage modeling approach and anisotropic warpage analysis. Due to the coupling of fiber breakage and anisotropic flow modeling, the fiber breakage directly influences the modeled cavity pressure, which is validated with experimental data.

Book Synopsis Discontinuous Fiber-Reinforced Composites by : Umesh Gandhi

Download or read book Discontinuous Fiber-Reinforced Composites written by Umesh Gandhi. This book was released on 2020-03-09. Available in PDF, EPUB and Kindle. Book excerpt: There are many books on composite material analysis, but most cover mainly continuous fiber materials, rather than those filled with discontinuous fibers, which are particularly attractive for large-volume and low-cost applications. This book provides the theoretical and practical background to design and use discontinuous fiber-reinforced polymer materials, with an emphasis on structural parts for the automotive industry. Moreover, the product of years of collaborative work between industry and academia is presented in an easy-to-use, comprehensive manner. The information provided makes it possible for someone with an engineering background to understand the micromechanics of discontinuous fiber-reinforced materials and, hence, analyze the structural performance of components designed with such materials. The book employs a practical approach to cover the key, unique capabilities that are critical for a successful structural analysis of discontinuous fiber-reinforced polymer structures: -Process simulation to estimate the condition of fibers in the finished parts, i.e., fiber length, orientation, and concentration -Capability to measure micro structure, i.e., fiber length distribution, fiber orientation tensors, and fiber concentration, etc. -Estimation of material properties in the part based on fiber condition, as well as environmental conditions such as temperature A broad range of areas is included, such as joining and assembly.

Book Synopsis Continuous–Discontinuous Fiber-Reinforced Polymers by : Thomas Böhlke

Download or read book Continuous–Discontinuous Fiber-Reinforced Polymers written by Thomas Böhlke. This book was released on 2019-08-05. Available in PDF, EPUB and Kindle. Book excerpt: Discontinuous long fiber reinforced polymer structures with local continuous fiber reinforcements represent an important class of lightweight materials with broad design possibilities and diverse technical applications, e.g. in vehicle construction. However, in contrast to continuous fiber reinforced composites, extensively used in the aircraft industry, there is still a lack of integrated and experimentally proven concepts for manufacture, modeling, and dimensioning of combinations of discontinuously and continuously reinforced polymer structures. This is partly ascribed to the complexity of the manufacturing processes of discontinuously reinforced polymers, with heterogeneous, anisotropic, and nonlinear material and structural properties, but also to the resulting bonding problem of both material types. This book addresses these issues, including both continuous and discontinuous fiber processing strategies. Specific design strategies for advanced composite reinforcement strategies are provided, with an integrated and holistic approach taken for composites material selection, product design, and mechanical properties. Characterization, simulation, technology, design, future research, and implementation directions are also included. Especially in the field of application of three-dimensional load-bearing structures, this book provides an excellent foundation for the enhancement of scientific methods and the education of engineers who need an interdisciplinary understanding of process and material techniques, as well as simulation and product development methods.
