Glass Transition Temperture (Tg) Measurements on Test Laminates Used in HANSA-3 Prototype II Development (Post curing Effect)

摘要

For the weight reduction of Hansa-3 prototype I, design consideration were slightly modified to fabricate a new version viz., Hansa-3 prototype II. In connection with this program laminates were fabricated using LY 5052 system with both carbon tape and glass fabrics for generation of design allowables. They were post cured and tested for mechanical properties as the degree of post cure directly influences the hot wet mechanical properties, the Tg of post cured specimens were monitored for both GFRP and CFRJ? specimens.
