Experimental Procedure for Lifetime Testing of Graphite Bundles under Constant Load

Abstract

An experimental procedure is presented for lifetime testing of graphite bundles under constant load. The attributes of the experiment are expedience in implementation and a substantial accumulation of information equivalent to a large number of single filament tests. To achieve the objectives of the experiment a specially adapted Instron machine was used with a digital process/controller. Two trial experiments were conducted using Hercules high strength graphite. The preliminary results are presented and the effects of inter-fiber friction evaluated. Keywords: Composite, Creep rupture; Viscoelastic deformation, Fiber life.
