Book Description :

Residual stresses are a common phenomenon in composite materials. They can either add to or significantly reduce material strength. Because of the increasing demand for high-strength, light-weight materials such as composites and their wide range of applications in the aerospace and automotive industries, in civil infrastructure and in sporting applications, it is critical that the residual stresses of composite materials are understood and measured correctly. The first part of this important book reviews destructive and non-destructive testing (NDT) techniques for measuring residual stresses. Various mathematical (analytical and numerical) methods for calculation of residual stresses in composite materials are also presented. Chapters in the first section of the book discuss the simulated hole drilling method, the slitting/crack compliance method, measuring residual stresses in homogeneous and composite glass materials using photoelastic techniques, and modeling residual stresses in composite materials. The second part of the book discusses residual stresses in polymer matrix, metal-matrix and a range of other types of composites. Moreover, the addition of nanoparticles to the matrix of polymeric composites as a new technique for reduction of residual stresses is discussed. Residual stresses in composite materials provides a comprehensive overview of this important topic, and is an invaluable reference text for both academics and professionals working in the mechanical engineering, civil engineering, aerospace, automotive, marine and sporting industries. Reviews destructive and non-destructive testing (NDT) techniques for measuring residual stresses Discusses residual stresses in polymer matrix, metal-matrix and other types of composite Considers the addition of nanoparticles to the matrix of polymeric composites as a new technique for reduction of residual stresses

Book Description :

The increased application of composite materials in lightweight structures leads to new integral design of structural parts, using the example of, an integral composite landing flap of an Airbus A320 aircraft. This offers possibilities to simplify the process chain, to decrease manufacturing costs and to have fibre fair structural design. The critical disadvantage of large integral designs is that process-induced deformations are a risk factor during the design phase of the manufacturing process, because rework is not always possible. Especially, the aircraft industry with its demands on high qualities / tolerances and the application of hot curing resin systems, requires knowledge-based methods for virtual process design to avoid time- and effort-consuming iterations. This thesis contributes to the understanding of the mechanism behind process-induced distortions and stresses related to the Resin Transfer Moulding (RTM) manufacturing process. The aim is to comprehend the phenomena, to identify related parameters and to present compensation strategies.

Book Description :

Fibre-reinforced plastic (FRP) composite materials are basically of two types. The first type is short fibres reinforced in a plastic matrix, and the other type continuous (long) fibres reinforced in a plastic matrix. The exact distinction between a short and a continuous fibre is discussed in Chapter 1. Continuous fibre-reinforced composite materials are referred to by many labels: FRP composites, advanced composites, fibrous composites, composite materials or simply composites. These terms are now generally accepted to mean the same type of material, namely, continuous fibre reinforced in plastic. In this book, the term fibrous composites is used to define a continuous fibre reinforced in plastic. Fibrous composites are presently in use for a variety of structural applica tions, and may offer an alternative to conventional metallic materials. The behaviour of fibrous composites subjected to a loading condition is very different from that of a metallic isotropic material. Therefore, 'new' analytical and testing methods are required to analyse a structural element and sections made from layered fibrous composites. There are a number of books written on the subject of composite materials. All of these are excellent in their content and achieve the authors' objectives.

Book Description :

Comprehensive numerical presentation of dimensional instability in composites Quantitative analyses for predicting deformations in all types of composite materials Evaluation of mechanical, thermophysical, environmental stresses over time Unique aid in design of composites for specific application conditions--------------------------------------------------------------------------------This book is a comprehensive introduction to the quantitative analysis of dimensional instability in composite materials. It will aid in predicting deformations in a wide range of composite materials products and parts, under mechanical, thermophysical, and environmental stresses over time. Written by an internationally known expert on the analysis of composites, this new work brings together the best quantitative methods and currently known data for understanding how composites become unstable over time. The technical insights and information in this book offer a practical foundation for engineering composite materials with better stability and increased performance. From The Author''s Preface "Dimensional stability predictions [in composites] require knowledge of not only mechanical behavior but also thermophysical properties and the response to environmental conditions and time. This book attempts to aid in the numerical prediction of dimensional stability properties. It is necessary to quantify the behavior of composites for many reasons. Composites compete with plastics, metals, and ceramics in numerous applications, and designers must be able to justify increase in cost or complexity in terms of precisely defined performance benefits...Only a quantitative understanding of potential deformations [in composites] will lead to confidence in their use...This book combines a judicious use of experimental data, together with current theoretical models. It summarizes the scope of potential sources of instability in composites to help the engineer estimate the magnitude of possible deformations. The book also contributes to outlining methods for dealing with deformations. Experimental methods are offered and reviewed for those who (wisely) do not rely solely on existing data and theory." --------------------------------------------------------------------------------TABLE OF CONTENTS PrefaceAcknowledgments Chapter I: INTRODUCTION· What is Dimensional Stability? · Historical Notes· Magnitude: Units, Range, Engineering vs. True Strain, Dependence on Measurement Chapter II: DIMENSIONALLY STABLE MATERIALS· Introduction · Metals and Alloys · Glasses and Ceramics· Polymers· General Composites · Composite Constituents· Metal Matrix Composites· Ceramic Matrix Composites· Polymer Matrix Composites· Carbon Matrix Composites· Natural Composites· Hybrid Composites· Shape Memory Materials · Functionally Graded Materials· Nanomaterials· "In situ" Composites Chapter III: MECHANICAL EFFECTS· Introduction · Composite Notation· Micromechanics· Macromechanics of Laminates· Orthotropic Materials· Curvature · Thickness Effects· Poisson''s Ratio· Edge/End Effects· Residual Stresses· Plastic Deformation · Microyield Stress· References Chapter IV: ENVIRONMENTAL EFFECTS-TEMPERATURE· Introduction · CTE of Constituents · Micromechanics· Macromechanics· Volumetric Expansion· Resin Matrix Composites · Metal Matrix Composites· Ceramic Matrix Composites· Uniformity of CTE· Structural Forms· References Chapter V: ENVIRONMENTAL EFFECTS-MASS ABSORPTION· Introduction· Moisture Content· Moisture Distribution· Moisture Induced Strain · Coatings · CME Data Chapter VI: ENVIRONMENTAL EFFECTS-RADIATION · Introduction· Space Radiation· Radiation Effects on Micromechanical Properties· Radiation Effects on Thermophysical Properties· Nuclear Radiation · UV and Miscellaneous Radiation Chapter VII: ENVIRONMENTAL EFFECTS-TIME · Introduction · Temporal Stability · Relaxation of Residual Stresses· Physical Aging· Chemical Aging · Thermal Aging· Post Curing Chapter VIII: CREEP· Introduction· General Creep Behavior· Creep of Composite Constituents· Microstructure· Loading Conditions· Creep Mechanisms· Recovery and Relaxation· Damage Development· Prediction of Creep Strains Chapter IX: INTERNAL DAMAGE· Introduction· Thermally Induced Microcracking in FRPL· Mechanical (Stress) Cycling in PMC· Dimensional Changes due to Microcracking· Effects of Microcracking on Dimensional Stability, Effect on CTE, Thermal Cycling of PMC, Effects on Micromechanical Properties · Methods to Minimize Microcracking· Thermal Spikes· Reverse Thermal Effect· Thermal Cycling of MMC· Thermal Cycling of CMC· Microcracking and Moisture· Role of Fiber/Matrix Interface· Surface Damage Chapter X: COMBINED EFFECTS· Introduction · Thermoelasticity· Effect of Stress on Thermal Expansion· Hygrothermoelasticity · Effects of Stress on Mass Diffusivity· Stress and Moisture Effects· The Mechanosorptive Effect· Moisture Cycling· Combined Stress-Moisture-Damage Chapter XI: MEASUREMENT TECHNIQUES · Introduction· General Metrology· Microyield Strength (MYS)· Thermal Expansion (CTE)· Moisture Expansion (CME)· Temporal Stability· Creep· Damage Induced Dimensional Changes· Techniques for Combined Effects· Related Techniques Chapter XII: APPLICATIONS· Introduction · Dimensionally Stable Requirements· Selected Applications: Aircraft, Antenna Structures, Automotive, Biomedical, Cryogenics, Electronics, Fabrication, Flywheels, High Temperature, Instrument Components, Large Space Structures, Metering Functions, Microwave Components, Mirrors, Optical Support Structures, Radiation Environments, Radomes, Smart Materials Technology, Spacecraft Components, Structural/Infrastructure, Wind Turbines, General Design Methodology Index
