Design and fabricate a 3D mold
This week's task was to design and fabricate a 3D mold (~ft2) and produce a fiber composite part in it. I have never worked with composite before, so I decided to create something simple first. I decided to make a fruit plate. I used Fusion360 to design the mold.
Although I have used shopbot for many times, this was actually my first time running the machine by myself. I did a "roughing" cut and a "finishing" cut.
Produce a fiber composite
Matarial I needed to make the composite:
Put Plastic sheet on the mold that acts as the plee ply.
I applied epoxy to two layers of burlap. I wasn't sure about how much epoxy I should have applied, so I put as much epoxy as it all soaked. Then I put another plastic sheet as peel ply on burlap. However, I forget to put cotton to absorb excess epoxy.
I put the mold with peel ply to a vaccum bag, then vacuumed it.
Burlap Composites Plate
12 hours later, I checked the bag and it was very hard and fully cured.
Here is my plate! Although I didn't use contton to absorb extra spoxy, it turned out to be not too bad. Since I used two layers of burlap, my plate is actually very rigid.
I am using it as my fruit plate now!
