This handbook is the culmination of a five-phase program to develop standardized repair procedures for adhesively bonded aircraft structures. It recommends repair materials and processing methods. It identifies repair procedures for both small and large size repairs. It additionally includes information on equipment and tools and nondestructive inspection techniques. (Author).

This Handbook provides methods of repair for adhesive bonded and composite structures, the identification of suitable materials and equipment for repairs, and methods of inspection before and after repair. Repair methods included are for composite laminates containing fiberglass, graphite, or Kevlar reinforcements in organic matrices, and sandwich structures containing honeycomb, foam or balsa cores with either metallic or composite laminate skins. Materials, tools, and equipment used in repairs are also described and their sources are presented.

The conventional approach to through-life-support for aircraft structures can be divided into the following phases: (i) detection of defects, (ii) diagnosis of their nature and significance, (iii) forecasting future behaviour-prognosis, and (iv) pre scription and implementation of remedial measures including repairs. Considerable scientific effort has been devoted to developing the science and technology base for the first three phases. Of particular note is the development of fracture mechanics as a major analytical tool for metals, for predicting residual strength in the presence of cracks ( damage tolerance) and rate of crack propagation under service loading. Intensive effort is currently being devoted to developing similar approaches for fibre composite structures, particularly to assess damage tolerance and durability in the presence of delamination damage. Until recently there has been no major attempt to develop a science and tech nology base for the last phase, particularly with respect to the development of repairs. Approaches are required which will allow assessment of the type and magnitude of defects amenable to repair and the influence of the repair on the stress intensity factor (or some related parameter). Approaches are also required for the development and design of optimum repairs and for assessment of their durability.

This handbook is written by two material and manufacturing process engineers with over 60 years of combined experience in government. The purpose of the book is to: (1) provide a standard method for repairing adhesive bonded and composite laminate structures; (2) identify suitable materials and equipment for making satisfactory repairs, and (3) discuss methods by which structures may be inspected both before and after repair. It is designed as a reference manual. The intended audience includes anyone who needs to find recommended information on materials or procedures for adhesive bonded structural repair that meets applicable safety and health standards.

A reference that offers comprehensive discussions on every important aspect of aluminum bonding for each level of manufacturing from mill finished to deoxidized, conversion coated, anodized, and painted surfaces and provides an extensive, up-to-date review of adhesion science, covering all significa

Engineered Repairs of Composite Structures provides a detailed discussion, analysis, and procedures for effective and efficient repair design of advanced composite structures. It discusses the identification of damage types and the effect on structural integrity in composite structures, leading to the design of a repair scheme that focusses on the restoration of the structural integrity and damage tolerance. This book teaches the reader to better understand effective and efficient repair design, allowing for more structurally effective repairs of damaged composite structures. It also discusses the application of the repair and what is needed in the forming of the composite repair to meet the engineering design requirements. Aimed at materials engineers, mechanical engineers, aerospace engineers, and civil engineers, this practical work is a must have for any industry professional working with composite structures.
