Abstract
Method and apparatus for producing objects from fibrous monolith composites are provided. Two- and three-dimensional objects can be prepared from a continuous fibrous monolith filament. The objects can have complex geometries.
Claims2
A process for fabricating fibrous monolith composites comprising:
- combining a first powder with a thermoplastic polymer binder and a thermoplastic plasticizer to create a uniformly suspended composition,
- combining a second powder with a thermoplastic polymer binder and a thermoplastic plasticizer to create a uniformly suspended second composition,
- warm pressing 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 mechanically-controlled surface to create a fibrous monolith composite.
