Abstract
A machine for fabricating a fiber-reinforced component by additive manufacturing is disclosed. The machine may have a surface, a matrix feed configured to deposit a plurality of matrix layers on the surface, and a fiber feed configured to deposit a fiber layer on at least one of the plurality of matrix layers. The deposition of the plurality of matrix layers and the fiber layer may be controlled by a computer.
Claims3
A method for fabricating a fiber-reinforced component by additive manufacturing comprising:
- depositing a matrix layer on a surface;
- depositing a fiber layer on a previously deposited matrix layer, the fiber layer comprising a continuous fiber;
- heating the matrix layer with a first energy-source in order to soften the matrix layer;
- and
- pressing the fiber layer into a previously deposited matrix layer with a pressure source, wherein the pressure source emits heated air under a pressure.
