  We construct flat 3-webs via semi-simple geometric Frobenius manifolds of
dimension three and give geometric interpretation of the Chern connection of
the web. These webs turned out to be biholomorphic to the characteristic webs
on the solutions of the corresponding associativity equation. We show that such
webs are hexagonal and admit at least one infinitesimal symmetry at each
singular point. Singularities of the web are also discussed.
