Titanium Sandwich Airframe Structure. Volume 1: Program Overview

Abstract

Mechanical properties of laser welded titanium (Grade 9, Ti3Al2.5V) honeycomb core have been developed by testing for density, compression, and plate shear using the applicable ASTM test standards. Additionally, panels were fabricated employing the same titanium honeycomb core material, constructed using bismaleimide (BMI) face sheets and a cyanate esther film adhesive. These panels were tested using applicable ASTM standards for tension and beam flexure of bonded panels. Much of the core in this study was coated with zirconium for improved adhesion performance. All testing was performed at "ambient" room/storage conditions. The panels were bonded using a proprietary bonding procedure that is ITAR-restricted. The procedure used in preparing the specimens is also discussed per the respective ASTM standards. Results are reported in the Final Report document. Five CDs make up the data volumes and contain the data sheets and failure plots.
