Book excerpt: Fiber reinforced composites are weakened when bolt or rivet holes pierce the laminate to form mechanical joints. Premature failures occurring in the joint area have been a well recognized problem. In this investigation, unidirectional (all 0 deg), bidirectional (±45 deg), and tridirectional (0 deg, ±45 deg) graphite fiber/epoxy resin composites were fabricated to form a series of double-lap bolted joint models. These were tested to measure the joint strength effectiveness of transversely isotropic boron film colaminated locally at 6 and 12 volume percent levels. Results show that the addition of film plies to the highly directional fiber laminae increases the joint strength and stiffness up to 200 percent, the chief contribution of the boron film being high bearing strength and resistance to shear distortion. A novel test method for bolted lap joints was developed in which the bolt head pressure was maintained constant by means of preloaded springs, thus eliminating the ambiguity resulting from an inconstant contribution of the bolt clamping friction to the total joint strength. The strength weight effectiveness of boron film reinforcement in this particular application is demonstrated.

Book excerpt: NSA is a comprehensive collection of international nuclear science and technology literature for the period 1948 through 1976, pre-dating the prestigious INIS database, which began in 1970. NSA existed as a printed product (Volumes 1-33) initially, created by DOE's predecessor, the U.S. Atomic Energy Commission (AEC). NSA includes citations to scientific and technical reports from the AEC, the U.S. Energy Research and Development Administration and its contractors, plus other agencies and international organizations, universities, and industrial and research organizations. References to books, conference proceedings, papers, patents, dissertations, engineering drawings, and journal articles from worldwide sources are also included. Abstracts and full text are provided if available.

This book was released on 1972 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: The joint strengthening effects of transversely-isotropic boron film reinforcement added to fibrous laminates has been demonstrated for single fastened joints in earlier experimental work. It was the configurations where multiple fasteners, rather than single bolts, transferred the load. Bidirectional (plus or minus 45 deg) graphite fiber/epoxy resin composites were fabricated to form a series of double lap bolted joint models, each containing three bolts at constant pitch distance. The specimens were tested to measure the joint strengthening effectiveness of colaminated boron/polymide film, introduced locally at 6 or 12 volume percent levels. The results were that such film additions increased the load transfer capacity of the joint systems nearly double that of the corresponding fiber-only specimens. (Modified author abstract).

This book was released on 1971 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: The joint strengthening effect of plane- isotropic boron film reinforcement added to fibrous laminates was investigated. Uniaxial, bi-axial, and tri-axial graphite fiber/epoxy resin composites were fabricated to form a series of double lap bolted joint models. There were tested to measure the joint-strength effectiveness of the plane- isotropic boron film when added locally at 6 and 12 volume percent levels. The results showed that the addition of omni-directional film plies to the highly directional fiber laminae increased the joint strength and stiffness up to 200%, the chief contribution of the boron film being high bearing strength and resistance to shear distortion. A novel test method for bolted lap joints was developed in which the bolt head pressure was maintained constant by means of preloaded springs, thus eliminating the ambiquity resulting from an unknown contribution of the bolt clamping friction to the total joint strength. The strength- weight-effectiveness of boron film reinforcement was demonstrated. (Author, modified-PL).
