Compare and contrast theoretical material properties (including atomic structure and bonding) for the materials identified in activity 1a compared with values obtained through destructive and non-destructive test methods as provided in the table below. In particular assess the data for density, tensile strength, strength to weight ratio (specific modulus), and operating temperature range

-steel (1045)

-aluminium (T4)

-unidirectional S-glass-epoxy

-carbon-epoxy fibre
