composites
Assignments;
- Read the material safety data sheet (MSDS) and technical data sheet (TDS) for the resins that you're using
- Design and fabricate a 3D mold and produce a fiber composite part in it
The resin and hardener we had available was Henkel's and so I went online to search for the safety and technical datasheets.
Of note were:
Composition/Information on Ingredients
First Aid measures
Fire Fighting measures
Accidental release measure
Handling and storage
Exposure controls.Personal Protection
Stability and Reactivity
Disposal conditions
For this assignment I wanted to work with the Bishop I had designed for Week12:Molding and Casting for my mold.
I opened fabmodules and opened the .png file that I had available from week12.
I resized the model from the fabmodules interface.
I inverted the .png file so as to create a negative mould and set it up for the rough mill and sent it to the machine.
Once the rough mill was done I prepared and sent the finish mill.
The result was...
Putting everything together in preparation to create composite...
I mixed the resin and hardener in a resin:hardener ratio of 2:1
I applied a small amount of petroleum jelly to allow the composite come off the mold. I applied the first layer of fibreglass and applied the resin mixture using a paint brush. I did this for 3 layers and finally...
I put the mold into an airtight static bag. I then used our handheld vacuum to create a vacuum.
3 hours later...
Assignment wise:
- Read the material safety data sheet (MSDS) and technical data sheet (TDS) for the resins that you're using
- Design and fabricate a 3D mold and produce a fiber composite part in it
