Abstract
A method for fabricating a model includes the steps of stacking successive layers of aluminum honeycomb core to a desired height to form a block, machining the block to within a desired tolerance of the desired final contour, applying a layer of modeling material such as syntactic epoxy to the outer surface of the block, and machining the layer of modeling material to the desired contour. The result is a model from which a mold or composite parts can be fabricated, using high temperature and pressure processes if desired.
Claims8
A method for fabricating a model comprising in sequence the steps of:
- stacking successive layers of aluminum honeycomb core to form a stack of a desired height;
- machining at least a portion of said stack to within a desired tolerance of a desired contour;
- applying a layer of modeling material to at least a portion of the outer surface of said stack;
- and,
- machining said layer of modeling material to the desired contour.
