Download or read book Structural Health Monitoring For Advanced Composite Structures written by M H Ferri Aliabadi and published by World Scientific. This book was released on 2017-12-18 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: Structural health monitoring (SHM) is a relatively new and alternative way of non-destructive inspection (NDI). It is the process of implementing a damage detection and characterization strategy for composite structures. The basis of SHM is the application of permanent fixed sensors on a structure, combined with minimum manual intervention to monitor its structural integrity. These sensors detect changes to the material and/or geometric properties of a structural system, including changes to the boundary conditions and system connectivity, which adversely affect the system's performance.This book's primary focus is on the diagnostics element of SHM, namely damage detection in composite structures. The techniques covered include the use of Piezoelectric transducers for active and passive Ultrasonics guided waves and electromechanical impedance measurements, and fiber optic sensors for strain sensing. It also includes numerical modeling of wave propagation in composite structures. Contributed chapters written by leading researchers in the field describe each of these techniques, making it a key text for researchers and NDI practitioners as well as postgraduate students in a number of specialties including materials, aerospace, mechanical and computational engineering.

Book Synopsis An Analytical Vacuum-Assisted Resin Transfer Molding (VARTM) Flow Model by :
Download or read book An Analytical Vacuum-Assisted Resin Transfer Molding (VARTM) Flow Model written by and published by . This book was released on 2000 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A closed form solution for the flow of resin in the vacuum-assisted resin transfer molding (VARTM) process is used extensively for affordable manufacturing of large composite structures. During VARTM processing, a highly permeable distribution medium is incorporated into the preform as a surface layer. During infusion, the resin flows preferentially across the surface, simultaneously through the preform, to a complex flow front. The analytical solution presented here provides insight into the scaling laws governing fill times and resin inlet placement as a function of the properties of the preform, distribution media, and resin. The formulation assumes that the flow is fully developed and is divided into two areas: (1) a saturated region with no cross flow, and (2) a flow front region, which moves with a uniform velocity, where the resin is infiltrating into the preform from the distribution medium. The law of conservation of mass and Darcy's Law for flow through porous media are applied in each region. The resulting equations are nondimensionalized and are solved to yield the flow front shape and the development of the saturated region. It is found that the flow front is parabolic in shape, and the length of the saturated region is proportional to the square root of the time elapsed. The obtained results are compared to data from fill-scale simulation and show good agreement. The solution allows greater insight into the physics process, enables parametric and optimization studies, and can reduce the computational cost of full-scale, three-dimensional (3-D) simulations.

Book Synopsis Simulation of the Vacuum Assisted Resin Transfer Molding Process by : Xiaolan Song
Download or read book Simulation of the Vacuum Assisted Resin Transfer Molding Process written by Xiaolan Song and published by . This book was released on 2004 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: A process model that includes the coupled phenomenon of resin flow and preform compaction was developed and used to simulate resin infiltration of a fibrous preform using the vacuum-assisted resin transfer molding (VARTM) process. Flow of resin through the distribution medium and preform were modeled as flow through porous media. The finite element/control volume method was used to calculate the infiltrating fluid pressure distribution and track the progression of the flow front. The simulation results were compared with data obtained during infiltration of a carbon fiber preform with an epoxy resin. The parameters measured include the flow front location, resin pressure, and preform thickness change. With accurate inputs, the flow front locations and resin pressure distribution can be accurately predicted. The predicted transverse displacements do not agree well with the experimental measurements. The reasons for the differences are discussed, and further investigations are recommended to develop a more accurate compaction model.

This book was released on 1996 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The increasing interest in the Resin Transfer Molding Process (RTM) evolved from its potential for reducing manufacturing costs, while increasing the capability of manufacturing complex parts. This manufacturing process like many other processes involves a large number of variables, consisting of both material and processing parameters. The present study uses statistical experimental design analysis as a tool to determine which of the various independent and controllable RTM process variables affect the mechanical properties of the laminates produced through the RTM process. The statistical experiment is conducted in two phases. In the first phase, ten independent and controllable RTM process variables are chosen for study. For the first time, a sieve design is used to eliminate variables that are of not much importance. In the second phase, the important process variables are re-experimented, and the range at which they produce a good response (Laminate) is studied. In contrast to earlier studies, the present study considers the interaction effect of all the variables. Vacuum assistance is used during the mold filling, and its interaction affect on other factors, and effect on mechanical properties is also analyzed. In line with earlier studies, three different tests (mechanical three point bending, short beam shear, and dynamic mechanical test) are conducted to examine the possibility that a single important process variable might not have the same effect on all of them.

Book Synopsis Interface Science and Composites by : Soo-Jin Park
Download or read book Interface Science and Composites written by Soo-Jin Park and published by Academic Press. This book was released on 2011-07-18 with total page 853 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of Interface Science and Composites is to facilitate the manufacture of technological materials with optimized properties on the basis of a comprehensive understanding of the molecular structure of interfaces and their resulting influence on composite materials processes. From the early development of composites of various natures, the optimization of the interface has been of major importance. While there are many reference books available on composites, few deal specifically with the science and mechanics of the interface of materials and composites. Further, many recent advances in composite interfaces are scattered across the literature and are here assembled in a readily accessible form, bringing together recent developments in the field, both from the materials science and mechanics perspective, in a single convenient volume. The central theme of the book is tailoring the interface science of composites to optimize the basic physical principles rather than on the use of materials and the mechanical performance and structural integrity of composites with enhanced strength/stiffness and fracture toughness (or specific fracture resistance). It also deals mainly with interfaces in advanced composites made from high-performance fibers, such as glass, carbon, aramid, and some inorganic fibers, and matrix materials encompassing polymers, carbon, metals/alloys, and ceramics. Includes chapter on the development of a nanolevel dispersion of graphene particles in a polymer matrix Focus on tailoring the interface science of composites to optimize the basic physical principles Covers mainly interfaces in advanced composites made from high performance fibers
