Abstract:

The procedure referred to as thermal liquefaction allows production of Intermediate Ceramic Composites (ICC) from lunar simulants with various admixtures. For their use as structural materials for construction on the Moon it is essential to study their mechanical properties: flexural, compressive, ductile, fracture and fatigue. Flexural and compressive testing of the composites are discussed by Desai and Girdner (1992). This paper describes development of a new tension testing device, manufacture of flat and cylindrical specimens and tensile and compression testing, and constitutive modeling for tensile, damage and fracture behavior.
