Metal Matrix Composite Bonding Characteristics and Impact Properties.
Abstract
This research program objective is to develop an understanding of the surface characteristics and bond behavior in metal matrix composites as related to the impact properties. The initial part of this program addresses itself to bonding of aluminum foils with different surface treatments. Scanning electron micrographs revealed the presence of A1/Fe compounds. Following this, extensive efforts were directed at identifying an etchant to remove such heterogeneous phase identified to be an aluminum iron compound, Al3Fe. After an extensive literature review, three chemical etchants were selected, the aluminum alloy foils were chemically tested, and the etched foils were evaluated by scanning electron microscopy. Single layered monotapes were then formed and evaluated by bond integrity testing (BIT). Following this, further studies were performed on evaluation of hybrid metal/metal foil combinations consisting of aluminum alloy foils against titanium or stainless steel foils. The study was next directed at fabrication of single-ply boron/aluminum panels and then in formation of hybrid titanium/aluminum/boron (TAB) and stainless steel/aluminum/boron (SAB) single-ply panels.
