Uncertainty Factors and Their Effects in Experimental Results of Composite Structures

Abstract

Uncertainty factors can be considered as major factors influencing experimental results. This article reviews the potential impact of uncertainty in manufacturing composite structures. It also describes the impact of the following factors on the testing process: Void content, curing time, tester calibration read error, interlinear bond, and mixed striping. Test specimens of hexagonal tubes were selected for testing. Test specimens are tested under axial compression tests. Observation and test results showed that the un-certainty factor significantly influenced the final result. Furthermore, the possible reasons for these findings and their implications were discussed.
