Abstract : Process variables which can affect the tensile strength of glass-reinforced aluminum composites have been systematically investigated. Although it has been found that there is a substantial difference in the tensile strength of samples made by the hot pressing technique and those made by the vacuum injection technique, small variations of the percentage of glass present in samples made by the vacuum injection technique have little effect on the tensile strength. An optimum predrying technique for metal coated fibers before impregnation with aluminum was determined. The drying cycle consists of drying the fiber for several hours at 300F. and then increasing the temperature to 600F. for at least 20 minutes. Increasing the fluidity of the aluminum alloy also resulted in better tensile strength, largely due to the ease with which such alloys penetrated the aluminum coated fiber bundles. It was observed that higher temperatures would enhance the ability to penetrate the fiber bundles more easily, but an upper limit of 1600F. is imposed by the increased reactivity of the aluminum at the higher temperatures.
