Abstract:
A process for fabricating a green fibrous monolith composite article comprising:combining a first powder with a thermoplastic polymer binder to create a uniformly suspended first composition, combining a second powder with a thermoplastic polymer binder to create a uniformly suspended second composition, forming the first and second uniformly suspended compositions to create a feed rod having a first portion of the first composition surrounded by a second portion of the second composition; and extruding the feed rod through a deposition nozzle onto a surface in a directed orientation by mechanically manipulating at least one of the deposition nozzle and the surface to form a green fibrous monolith composite article.
