Before we laminate the foam/glass/carbon on our chassis members, we want to build a test fixture and run samples to optimize the layout for best torsional rigidity vs weight.

We will save one of these pictured samples as a control and layup the other three in varying combinations of glass and carbon. We will then test the three for the best stiffness/weight ratio and against the control to see if any of the three give us the improvement we need. If none of the sample are rigid enough, we will go another round of composites over the existing layers and test again.

We hope to have these samples/tests done by the end of this weekend so we can then start layup on the chassis proper.
