Abstract In this study, a multi-parameter analysis, using Taguchi method for design of experiments, has been conducted to investigate the optimum curing conditions for E-glass fabric/epoxy laminated composites. The independent variables in the L25 Taguchi orthogonal array were heating rate a, curing temperature TC and curing time tC, including five levels each. Tensile and 3-point bending tests were performed for each experiment number (run number) of the Taguchi L25. In this study, the significant factors for both tensile and flexural performance were temperature and time at 95% confidence level. Specifically, the tensile performance was affected almost equally by both curing temperature and time (32.71% and 35.89%, respectively). The flexural performance was mostly affected by curing temperature (44.02%) and secondarily by curing time (31.52%).
The SAE Aerospace Information Report (AIR) is intended to be used as a process verification guide for evaluating implementation of key factors in bonded repair of fiber reinforced composite structure in a repair shop environment. The guide will be used in conjunction with a regulatory approved and substantiated repair, and is intended to promote consistency and reliability.
This guidebook will assist in the design and integration of composite commercial aircraft structures that exhibit improved durability, maintainability and repairability. For international use by composite aircraft component designers, this book identifies problems that have occurred with various composite components and provides potential problem-solving recommendations. Written primarily for composite design engineers, Design of Durable, Repairable, and Maintainable Aircraft Composites should also prove valuable to those in structural engineering, materials and processing, product support, advanced product development, systems engineering, technical services, and maintenance operations.
SAE CACRC has produced several standards, each representing the best-practice, recommended minimum training syllabus for the aforementioned target groups. The purpose of this document is to promote the use of these SAE standards, particularly for developing training programs for employee training, qualification in airlines and maintenance organizations, and as reference in regulatory guidance material. It summarizes, as a quick reference, the content of each training document and its relation to and interaction with other training documents. Thereby it allows users to select the appropriate training documents and syllabi to establish a comprehensive, sequential training program build-up customized to the specific needs of the aforementioned functions (see figure). This document does not intend to introduce new training content/syllabus.
To create Guidance on the essential information/data that is needed to correctly assess damage and document the damage. A guidance document is proposed as the initial step in which it is documented what essential information is required for a composite repair with the aim to reduce to number of back and forward communications, improve the documents to define damage such as mapping, damage descriptions, sketches, pictures. CACRC Procedures Task Group will be drafting the document.
Increased use of advanced composite structural materials on aircraft has resulted in the need to address the more demanding quality and non-destructive testing procedures. Accordingly, increased utilization of solid laminate composites is driving changes to airline NDT training requirements and greater emphasis on the application of accurate NDT methods. Modules, including an introduction to composite materials, composite NDI theory and practice, special cases and lessons learned, have been produced in addition to various hands-on NDT exercises. A set of proficiency specimens containing realistic composite structures and representative damage has been designed in order to reinforce teaching points of the course and “test” inspector’s proficiency. Extensive details of the course modules, hand-on exercises and the proficiency specimens are all presented in this report.
The purpose of this specification is to allow procurement of a defined material corresponding to statistically derived material properties published in CMH-17. This material is intended for use in laminate applications with a service temperature up to 180 °F. They are typically used in structural applications requiring high strength and stiffness.
