Assignment Week12
Composites
This week’s assignment is "Design and make a 3D mold (~ft2), and produce a fiber composite part in it”.
I tried to make motorcycle fuel tank that made with FRP.
Making 3D mold
First I make 3D data of tank using Rhinoceros.
Tank's shape has flat surface and curved surface.
Next, I put cuboid block data over tank's shape.
And, make female die's shape using boolean subtraction command of Rhinoceros.
Female die's data can download here.
Next, I challenged to make the "female die" that be made with MDF.
I used "123D Make" This software can translate 3D data to Press-fit construction.
We can download it here.
.
I import female die data and setting information.
Laser cutter setting
MDF size : T2.5Feed : 10mm/sec
Power : 30%
It can download here.
.
Press-fit construction have many many chinks. So I infill it with clay and stick aluminum sheets inside of female die.
Make FRP Parts
I make FRP parts using my mold.
FRP made by 2 kind of synthetic resin and glass fiber sheet.
Grass fiber
2. Mix 2 synthetic resin liquid as fixed rate.
I used polyester resin, and curative agent.
5. Break female die, and scratch clay and aluminum sheets.
Complete!!
