Pagination or Media Count:
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 processcontroller. 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.
