Design and make a 3D mold (~ft2), and produce a fiber composite part in it.
This week assignment is very interesting and I want to use composite technology to make something. I try three times to produced composite. Failed for the first times and second times, but third times and succeeded
First times I designed small chair, so I have to design a 3D mold before mill the board on the CNC. I mixed the white latex and finer, and then add some wood to strength the structure. Failure! Because ignored the characteristic of white latex.
Second times I mixed epoxy and glass fiber to produced my composite. In this process, I made another mistake that ignored how to easy release. So it is failure too.
Third times , I asked for help and searched in the google, I made a decision to design a adapter for CNC and cleaner. At this times, In order to easy release and I used cardboard to design my 3D mold.
Figure the Epoxy system. The mixture's scale of Epoxy and Hardener is (0.5-1):1.
Put the mixture of Epoxy and hardener to stick on the mold's surface. And then put the small glass fiber to stick on the surface. In this process, I had to stick the mixture and glass fiber uniform distributed on the surface for kept the smooth surface.
1.Dsigned the mold with Rhino.
2.Mill the board.
1.How to used CNCRouter to Mill the big 3D mold.
2.Composit material is very interesting thing.
3.Have to take care youself when you used Epoxy and fiber,because it is very dangerous.
