Certification Testing Methodology for Composite Structure. Volume 1. Data Analysis

Abstract

This research developed a certification testing methodology for composite structures. The existing composite static strength and fatigue life data are analyzed statistically to determine the influence of test parameters on the scatter of composite data. Guidelines to use the composite data scatter in structural certification are recommended. Various approaches to composite structures certification are analytically evaluated. The approaches evaluated are: scatter factor approach, load enhancement factor approach, ultimate strength approach and change in spectrum approach. The capability, advantages and disadvantages of each approach to determine the minimum life and/or strength are fully discussed. Keywords: Certification, Composite materials, Aircraft structures, Fatigue.
