SIDER Testing of Impact Damaged Sandwich Panels

Abstract

This report presents the results of applying the Structural Integrity and Damage Evaluation Routine (SIDER) testing technique to four large composite sandwich panels. Each of these panels is a sandwich core construction with E-glass facesheets. All of the facesheets were made using 24 oz. E-glass woven roving layed up in a warps parallel configuration to a thickness of 0.25 in. The results are for a single SIDER analysis of each panel, and therefore are indicative of stiffness variability in the panels. The SIDER testing successfully identified impact damage areas created from drop weight impact testing.
