In order to determine which ablatives to use for our nose cone (and as a helpful guide for future purposes), we are setting up a test rig that uses a propane blowtorch to heat small samples of fiberglass. This document from Apogee Components was used as inspiration for this test procedure. Apogee Newsletter
