Multidisciplinary Design and Optimization of Aerospace Composite Materials is a collection of ten SAE technical papers focusing on the design analysis of aerospace composite structures from the perspective of various disciplines. The book concentrates on the following aspects: Analytical methods for weight design of aircraft structures, including a parametric geometry model capable of generating dedicated models for both aerodynamic and structural solvers. Methodologies for evaluating the structural performance of carbon/epoxy composite panels. An aerodynamic design of flexible wings made of composite structures. Thermal design and analysis of composite enclosures. Methodologies for analyzing the acoustic performance of composite structures, including the design optimization method to evaluate the acoustic performance in terms of transmission loss (TL) of various composite panels. The lightening effect on composites, presenting a theoretical method to compute the electrical current propagating through composite structures due to lightning strikes. The issue of fire resistance as most polymer resins are flammable once the respective ignition temperatures are reached. A probabilistic-based reliability analysis of the composite structures. The method is demonstrated on a graphite/epoxy composite space habitat subjected to the debris attacks. A sustainability analysis of aircraft composite materials, including improved durability, less maintenance, and lower energy consumption.

Since the successful production of carbon fibers in early 1960s, composite materials have emerged as the materials of choice for general aviation aircraft, military aircraft, space launch vehicles, and unmanned air vehicles. This has revolutionized the aerospace industry due to their excellent mechanical and physical properties, as well as weight-reducing ability. The next- generation material development model should operate in an integrated computational environment, where new material development, manufacturability, and product design practice are seamlessly interconnected. Materials and Process Modeling of Aerospace Composites reports recent developments on materials and processes of aerospace composites by using computational modeling, covering the following aspects: The historical uses of composites in aerospace industry, documenting in detail the early usage of composite materials on Premier I by Raytheon to recent full-scale applications of composites on large commercial aircraft by Boeing and Airbus. An overview on the classifications of composites used in aerospace industry, ranging from conventional glass- fiber reinforced composites to advanced graphene nanocomposites. The recent work on computational material engineering on aerospace composite materials, including fundamental computational frame work and case studies on the modeling of materials and processes

Focuses on the latest use of CAE (Computer-Aided Engineering) methods in design and failure analysis of composite materials and structures. This volume begins with a brief introduction to the design and failure analysis of composite materials, and then presents some recent, innovative CAE design examples of composite structures.

Divided into four sections, this title covers Body Structures, Powertrain Components, Suspension Components, and Electrical and Alternative Vehicle Components. The composite design examples presented come from the major OEMs and top-tier suppliers and are most relevant to the automotive materials challenges currently faced by the industry.

This book is segmented into three sections and includes eleven hand-picked technical papers covering processing and characterization of biocomposites; automotive applications of biocomposites; and offering a perspective on automotive sustainability. It is a must read for those interested in the growing importance of composites used in automotive applications.
