  In this work we present a new class of braneworld models, where the
superpotential function may be decomposed in a very specific form, but still
embracing, which allows considerable simplifications in the field equations. We
exemplify the method with two specific models that are extended versions of
superpotentials already considered in the literature. As one can see in the
examples, the braneworld scenarios obtained here present very interesting
features, such as split brane mechanism and asymmetric warp factor shape, which
is essential to address the hierarchy problem in the context of thick brane
scenarios.
