Abstract
In this paper, the determination of compressive strength of an unidirectional lamina (carbon/epoxy composite), using the Back-Out Factor correction of experimental data, is presented. Since early ’70s, many methods were developed to deduce a compressive characterization of a composite material, each of which has been based on a different way of applying load to specimens. After a detailed examination of these methods, the ASTM D 6641/D 6641M-09 Test Method has been chosen due to its advantages, i.e. load application to the sample (end load combined with shear load), measurement reproducibility and experimental equipment quite simplified. The experimental equipme...
