Week 5 Progress

This week we came across new research in contact mechanics that suggested we elongate our scales in order to reduce friction. At the same time, we decided to change the shape as well.  We went from octagons and squares to elongated hexagons, in order to keep the design more simple. Also, we experimented with the actual material the scales will be printed out of, and decided to half all dimensions to what is detailed below.

In addition to scale progress, two adhesives were ordered. One was a plastic to rubber glue to attach the scales to the D3O sheet, and fabric to rubber glue to attach the pad on the other side of the D3O. Also, we received the D3O and found it is less shock absorbent than expected. Thus, we have purchased a sprayable rubber undercoating to thicken this layer.
