Experimentation and Analysis of Compression Test Methods for Single Filament High Performance Fibres

Abstract

The simple and reliable single filament test methods for predicting the compressive properties of fibers are a must for developing activities of fibers in laboratories because of difficulties in composite compression test methods. Therefore, in this study, two single filament compression test methods, which are elastic loop and bending beam test, are conducted for several polymeric fibers including Kevlars, PBO and PBZT and a few carbon fibers such as T-50 and P-75S, in order to obtain their compressive properties. Also the compressive failure modes of fibers, which occur as a kink band formation in polymeric fibers and as a fracture in carbon fibers are investigated. In addition, a FORTRAN program is written for numerical analysis of non-linear geometry elastica problems such as bending a single fiber with large displacements. Keywords: Polymer fibers, Compression, Elastica, Elastica loop bending beam, Kink bands, Kevlars.
