There are 2 types of Fiber-reinforced composite
material. Continuous (aligned) and discontinuous(random or
aligned)
If we have aligned composite, how can we know it is discontinuous?
And what is difference with random discontinuous?

A continuous and aligned fiber-reinforced composite is to be
produced consisting of 30 vol.% aramid fibers and 70 vol.% of a
polycarbonate matrix. The elastic modulus values of aramid fibers
and polycarbonate matrix are 131 GPa and 2.4 GPa, respectively.
Assume that the composite has a cross-sectional area of 320 mm2 and
is subjected to a longitudinal load of 44.500 N.
