  In this work we investigate the issue of gravity and fermion localization and
resonances in $(4,1)$-branes constructed with one scalar field coupled with
gravity in deformed models. Such models give solutions for the scalar field
that is the usual kink solution in the extra dimension for a parameter $p=1$
and deformations with a two-kink profile for odd $p>1$. Gravity is localized
and resonant modes are found for small values of $p$. The coupling between the
scalar field and spinors is a necessary condition for fermions to be localized
on such branes. After performing a chiral decomposition of the five-dimensional
spinor we found resonances with both chiralities for all odd $p$'s. The
correspondence between the spectra for left and right chirality is guaranteed
and Dirac fermions are realized on the brane. The increasing of $p$
characterizes the formation of branes with internal structure that turns the
gravitational interaction more effective for fermions aside the brane,
increasing their lifetime. The influence of the internal structure of the
branes and the presence of resonances for gravity and fermionic modes is
addressed.
