Experiment_2 and 3 Evaluation

Vertical vs. horizontal fabric casting

In both experiments we used a rigid frame formwork to hold the membrane in place. The fabric membranes were manipulated in various ways to test the material. These experiments where executed to gain a better understanding of how fabric acts as a formwork when used in a vertical or horizontal cast.

We discovered that it was very challenging to control the deformation. Especially in the vertical cast you really had to take gravity into consideration. When working with such a stretchy material it is important that you work with gravity as a design factor. This made it very had to make any accurate predictions how the final elements would be shaped.

Our trouble with controlling the deformation would probably have been less significant if we had used a more firm fabric or a thicker material (like a rubber).

On the positive side the elements had a beautiful surface structure resembling the surface of the fabric. Some of the casts had even been slightly dyed from the fabric.
