% 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.
