Book Description
Equations for predicting the theoretical stresses and mechanical properties of fiber/metal laminates were derived. These were applied to a model high temperature laminate system based on 8OO9 aluminum and glass fiber reinforced U-25 thermoplastic polyimide. The effects of aluminum surface treatment on bond strength were investigated; chemical surface treatments gave superior bond strength compared to mechanical treatments. Adequate bond strength was obtained using simplified and environmentally safe surface preparation techniques. The tensile yield and ultimate strength, elastic modulus, fracture behavior, dynamic mechanical behavior, chemical resistance, and fatigue resistance of the laminate were investigated. Most properties were found to correlate well with the theoretical predictions. The laminate showed excellent strength retention at temperatures above 200 deg C. Fatigue resistance as- processed was found to be comparable to monolithic 8009. Post-stretching the laminate was shown to increase both fatigue life and yield strength substantially.

Book Description
Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS)* at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dis semination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volumes were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 39 (thesis year 1994) a total of 13,953 thesis titles from 21 Canadian and 159 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this impor tant annual reference work. While Volume 39 reports theses submitted in 1994, on occasion, certain uni versities do report theses submitted in previous years but not reported at the time.

Book Description
Fibre--metal laminates are sandwich materials comprised of altering layers of fibre-reinforced composites and metal alloys. These materials can offer superior properties compared to the monolithic constituents such as superior specific strength compared to metals and better impact and fatigue resistance than composite materials. The use of fibre--metal laminates is currently restricted to specialised applications where the superior properties justify the high cost. This is due to the increased manufacturing time and cost over conventional materials. A method for mass production of fibre--metal laminates would allow them to be integrated more easily into existing production facilities and greatly reduce the cost associated with their use. This thesis investigates the stamp formability of fibre--metal laminates using two distinct materials; one laminate based on a self-reinforced polypropylene composite and the other based on a glass-fibre reinforced polypropylene composite. Specimens of varying geometry were stretched over a hemispherical punch to elicit different deformation modes in the fibre--metal laminates and a non-contact optical measurement system was used to measure the surface strain during deformation. These experiments analysed the effect of the deformation mode on the formability of the laminates. The results from the experimentation were used to assess the deformation behaviour of the fibre--metal laminates and to identify the safe forming limits of the materials. It was found that the fibre--metal laminates can be formed in a similar manner to monolithic metals. The self-reinforced polypropylene laminate was found to exhibit superior formability to monolithic aluminium whereas the glass-fibre reinforced polypropylene laminate showed reduced formability. In addition, the effect of temperature on the formability of the laminates was investigated. The temperature did not have a significant effect on the deformation behaviour during the forming process in either fibre--metal laminate and no increased formability was exhibited by the glass-fibre reinforced polypropylene based laminate. However, the self-reinforced polypropylene based laminate showed improved formability at elevated temperatures. Two significant findings were identified; the friction interaction between the specimens and the tooling has a major effect on the forming of the laminates, and the forming limits of the aluminium are improved when bonded to self-reinforced polypropylene composite. The finite element analysis software ABAQUS/Standard was chosen for simulation of fibre--metal laminate forming. Tensile tests were performed to obtain the mechanical behaviour of the constituent materials, where the composites were simulated using non-linear elastic orthotropic material models and the aluminium using an elastic-plastic model. The experimental forming results were compared to the simulation and it was found that the simulation could accurately represent the general forming behaviour of the laminates. There was difficulty in matching some of the glass-fibre reinforced polypropylene laminates due the non-homogeneous behaviour of the composite. Results from the simulated specimens were used to assess the deformation of the composite, which could not be directly observed in the experiments, and to determination a preliminary failure condition of the composite experiencing stretch forming using the predicted strain in the failure region.
