WEEK 14-
COMPOSITES

Objective:

This week I had to design a 3D drawing and cut it. Following that, I would create a fibre composite.

Design:

I used Tinkercad software to create my drawing. I chose a a column shape that is available and did some editing and extruding to get a shape with a several columns lined up in parallel to each other. The shape was extruded about 15 mm above the flat surface, and the full design had an area of 30x30cm.

Final design

Cutting Process:

The next step after the design, is to cut it using the CNC machine. Prior to cutting, I transferred the file .STL and used the software ARTCAM to make the file compatible to cut.

My design on ARTCAM software:

My design finally cut and polished

(After the cutting, I realized that my design looked like the window of a jail cell.)

Continuing the composite process. I needed to cover the entire surface with tape. This is required so that the resin that I will spread later over the surface will not stick.

Surface completely covered with tape.

Epoxy Resin containers

The Final stage:

After the resin dried, I had to remove the cloth from the wooden board. The shape that came out was the composite. It must be a hard surface and the design is visible.

The Final product:

Materials used:

- 2 types of Epoxy Resins
- Cloth
- Scissors
- Transparent Plastic sheet
- A Sack

Difficulties:

- When I was placing the Epoxy Resin on the wood design, It seems I put too much. Therefore, it took an extra 2 days to dry instead of just 24 hours.
