This book was released on 1986 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents initial results of an experimental study of the dynamic deformation and dynamic fracture behavior of a 2124-T6 aluminum alloy reinforced with 13.2 v/o Silicon carbon whiskers. Results are compared with the quasistatic behavior and with the behavior of the unreinforced 2124-T6 aluminum alloy. Two types of tests are described, one to provide static and dynamic stress-strain curves of the material in shear and the other to measure static and dynamic values of the critical stress intensity factors, K sub Ic and K sub Id, for tensile fracture. Results show that the presence of the reinforcing whiskers raises the dynamic and static flow stress of the material in shear. It is also evident that the reinforced material has considerably more ductility in shear than it has in axial deformation. As expected, the fracture response, as measured by the critical stress intensity factor K sub Ic, is not as favorable for the reinforced material as for the unreinforced. However, dynamic loading raises the value of K sub Ic for the reinforced material while producing almost no change in the unreinforced. For the reinforced material, the rate of loading is important in determining toughness, as measured by the value of K sub I, but has little influence on the stress-strain behavior in shear.

Available in PDF, EPUB and Kindle. Book excerpt: This study addresses the need for dynamic mechanical properties of advanced materials which are available only in small quantities by evaluating the ability of the Piezoelectric Ultrasonic Composite Oscillator Technique (PUCOT) to measure the dynamic modulus of small specimens of fibrous and particulate metal matrix composites. This is accomplished by measuring the dynamic modulus of several small rod or bar-shaped specimens of 6061 aluminum reinforced with silicon carbide fibers or particles (Al/SiC) at room temperature with the PUCOT. The fiber or particle volume fractions of the Al/SiC specimens vary from 8 to 56 percent and void volume fractions range from zero to 15 percent. The results are examined in terms of the dynamic modulus and specific dynamic modulus as a function of reinforcement volume fraction. Experimental results show that the modulus versus volume fraction for the fiber-reinforced composites deviates from the linear rule-of-mixtures due to the presence of voids and fiber damage. For the particulate composites, the modulus values fall within the bounds predicted by variational principles. A "strength of materials" approximation based on the assumption of cubic particles has limited success in predicting the particulate composite data. The results demonstrate the ability of the PUCOT to measure accurately the dynamic modulus of small specimens with minimal specimen preparation.

Book excerpt: You are no longer to supply the people with straw for making bricks; let them go and gather their own straw. Israelites using bricks made of clay and reinforced with straw are an early example of application of composites. The individual constituents, clay and straw, could not serve the function by themselves but did when put together. Some believe that the straw was used to keep the clay from cracking, but others suggest that it blunted the sharp cracks in the dry clay. Historical examples of composites are abundant in the literature. Significant examples include the use of reinforcing mud walls in houses with bamboo shoots, glued laminated wood by Egyptians (1500B.C.), and laminated metals in forging swords (AD. 1800). In the 20th century, modern composites were used in the 1930s when glass fibers reinforced resins. Boats and aircraft were built out of these glass composites, commonly called fiberglass. Since the 1970s, application of composites has widely increased due to development of new fibers such as carbon, boron, and aramids, and new composite systems with matrices made of metals and ceramics. This chapter gives an overview of composite materials. The question answer style of the chapter is a suitable way to learn the fundamental aspects of this vast subject. In each section, the questions progressively become more specialized and technical in nature.
