% The following properties are measured at room temperature and are tensile
% in a single direction. Some materials, such as metals are generally
% isotropic, whereas others, like composite are highly anisotropic
% (different properties in different directions). Also, property values can
% range depending on the material grade. Finally, thermal or environmental
% changes can alter these properties, sometimes drastically.
