Exercise 14

Composite

In this assignment I planned to make a composite of Dalek. The model used here is the silhouette of my final project. Below are some early trials using glue and fabric without any further materials. The mould is made with a milling machine see

Then I used the laser cutter to cut out the silhouette of the dalek and an aproximately 1.5 mm smaller version to fit the form when the composite is inserted. Since we do not have a vacuum table available I had to stick to compression. Using syntetic resis eproxy and cotton fabric enclosed with plastic foil I made this composite. The foil results in less adherence between the mould and the composite after dry out. To apply enough pressure I used four clamps at the edges and a piece of lead on top. The design files for the mould can be found here.
