 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. First of all, I created a shape in Fusion containing curves because I was interested in how the material would respond to the curves.

 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. 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.

 The composite was a little difficult to remove from the mould - perhaps I didn't use enough silicon spray to separate the fabric from the mould. Also, the shine didn't work over the whole top of the composite - particularly in the parts that were depressed. Perhaps making a negative mould to press all the parts evenly would have fixed this problem. The composite was a little difficult to remove from the mould - perhaps I didn't use enough silicon spray to separate the fabric from the mould.

 I was surprised and pleased by the strength of the final composite and the fabric took the curves of the mould well. When sawing the edges of the composite, the material was less hard - I realised that I needed to use more epoxy solution at the ends. I was surprised and pleased by the strength of the final composite and the fabric took the curves of the mould well.
