Abstract

Tension and compression properties of continuous FP and W fiber reinforced aluminum composites have been characterized at a nominal strain rate of 10−4 s−1. Tests were conducted on specimens with fibers oriented at 0 deg, 30 deg, 60 deg, and 90 deg to the specimen axis. Compression properties of these composites were evaluated using specially designed compression jigs. The variables studied include fiber orientation and specimen height to width ratio. In all the tests Wood’s metal pot was used to ensure the alignment of the specimen axis with the loading direction. In addition, a limited number of compression tests were conducted using IIT Research Institute compression fixture for comparison purposes. A test fixture for a tube specimen loaded biaxially was also designed and fabricated. A limited number of biaxial tests were conducted on FP-aluminum tubes to determine the fracture stress and to prove the test technique. Theoretical analyses and metallurgical examinations of test specimens have been performed to understand the strengthening and failure characteristics of these composites.
