Book Description
The results of a study to develop a reliable set of design allowables for type AS GRAPHITE/EPOXY; A HYBRID CONSISTING OF 4.0 MIL BORON/EPOXY AND TYPE AS graphite/epoxy; and boron/aluminum at room temperature and 350 F are presented. Classic lamination theory, supported by testing, has been applied to the filamentary controlled (0/+ OR -45/90) degree family of graphite/epoxy and boron-graphite/epoxy hybrid laminates. The higher transverse layer strength and stiffness of boron/aluminum usually eliminates the need for transverse layers in typical structural applications, therefore the (0/+ or -45) degree family of boron/ aluminum laminates has been chosen for design property determination. Such properties as elastic modulus, shear modulus, in-plane uniaxial strength, in- plane shear strength, coefficients of thermal expansion and major Poisson's ratio have been developed. Equations are presented for laminate strength under the action of combined in-plane loading and for bolted joint behavior. Bonded and brazed joints of these materials are handled by the Grumman joint analysis computer program STPS4. (Author-PL).

Book Description
A composite materials data bank system has been developed to store large amounts of test data. At present, extensive test data have been stored for A-S/3501 graphite/epoxy, 5.6 boron/6061 aluminum, and HT-S/710 graphite/polyimide. The data bank is an interactive computer software with cost-effective capabilities for performing a variety of analyses, including prediction intervals, confidence intervals, design allowables, and Weibull allowables. Printer plots are available for presenting raw test data or a variety of analytical results, including superimposed results, on a computer terminal for quick reference.

Book Description
The purpose of this tutorial is to provide a general introduction to metal matrix composite (MMC) materials and technology to individuals who have had little or no previous training in the field. This tutorial is also designed to acquaint new Department of Defense (DOD) contractors assigned to MMC programs with the breadth of the field and as a refresher for materials scientists and engineers who need a review of MMC technology.
