Material safety data sheet (MSDS) and technical data sheet (TDS)

The kit has two elements: resin (A) and a catalyst (B). They should mix in a proportion of 5 to 1. To prepare we do the next steps

• Part (A) should mixed for two minutes
• Put part (B) in the mixe
• Mix both elements for five minutes until to homogenize
• After homogeneize we must wait for three minutes

Aditionally, the kit resin must conserve in a temperature 18 - 40 C°. The MSDS TDS were read to implement this homework.

Design the Object

I decided to create the shell of structure like egg. This structure composes by five levels where each one can fixed with a support part. The challenge here is to keep the surface curve.

After assemble our design, I had not any idea about how to fill the structure. But after minutes I decided to fill with old newspapers to fill structure like an egg. After that, we are wrapping with stretch film.

Also, we cut linen patterns which is rectangle with 50 mm of height and 150 mm of width; and we separated the resin before mixing.

Apply petroleum jelly everywhere to prevent sticking. So mixing the resin and the linen patterns were soaking in resint to put it the structure. Also, we add other layer with red linen and repeat the process. Finally, we got structure but the surface was not uniform because the curve was not fill constant with newpapers.

Other composite

Other composite was designed to test the presion. So we design three experiments, one of then with presses, the second test was consisted on letting with resin and it exposed to air. and finall test did with inflation bag which we extracted air and the element were inside it.

Second test

Third test

After two days

Now, we concluded that the best texture was produced by the pressed between two layers, but they have low hardness. The hardest layer were exposed to air, I think that the weather can help it. Finally the elements in the bag were good but they are fragile if we want compare with the other test.
