Strip-Built Panel Strength Testing

Photographs of Samples

The following are photographs of the test samples after measuring their breaking strength. Unless otherwise noted all samples are made with e-glass and MAS brand epoxy resin.Clicking on the photo image will display an approximately life size enlargement of the samples.

The brown bit in the center of the picture is a sample after breaking it.
In this picture the top side of the sample is the "Compression" side,
and the bottom side is the "Tension" side.
