$($a$)($i$)$ First, find elastic properties $($Young$\text{'}$s modulus, Poisson's ratio and shear modulus$)$ for AS$4/$APC$2$ carbon

fibers and PEEK matrix material. $($ii$)$ Where did you find these results? $($iii$)$ Are the results reasonable? Note, peer

reviewed research journal articles are good sources of information, but remember to cite it$.$

$($b$)$ Calculate lamina elastic properties $E_1,E_2,$

$u{?}_{(}()()12),$ and $G_{12}$ for both the Hybrid Voigt$-$Reuss and Square Fiber mod$-$

els for materials in part $($a$).$ Treat the fiber as transversely isotropic and the matrix as isotropic. Note that the fiber

volume fraction is $0\mathrm{.}58.$

$($c$)$ Compare and comment on the correlation between the experimental test data given below in Table $1$ and your

predictions.
