This week, I produced a composite using layers of material with epoxy and catalysing solution, layered over a foam mould that I designed in Fusion 360 and milled it with the CNC milling machine, and then vacuumed it.

First of all, I created a shape in Fusion containing curves because I was interested in how the material would respond to the curves. I created a sketch, extruded it and rounded off the edges with the fillet tool.
In order to avoid any collisions with the drill tool, I had to ensure that the height of my model was less than 25mm, therefore I had to amend my design in Fusion and decrease its height.
Once the design was final, I set up the model for CNC milling using the CAM workspace in Fusion:
Once the mould was milled, I began the process of layering the materials with the epoxy mixture:
After the model was vacuumed, I removed the composite from the mould and tidied up the edges using the sawing machine. Here is the final product:
Problems
The composite was a little difficult to remove from the mould - perhaps I didn't use enough silicon spray to separate the fabric
