Carbon fibers experimental procedure

Procedure. A carbon fiber beveled electrode of about 10 diameter was polished and washed thoroughly with distilled water prior to each experimental run. The electrode was inserted into the vacuole of the Chara cell immersed in APW with the aid of micromanipulator under a binocular microscope. An Ag/AgCl reference electrode and a Pt wire auxiliary electrode were placed in the APW pool as illustrated in Fig. 15. The Chara cell was then left standing for 10-60 min in APW until the protoplasmic stream was restored. The measuring system was positioned inside a Faraday cage to minimize electrical noise pick-up. Differential pulse voltammetry was applied for the measurement. [Pg.481]

The remaining part of this chapter will review the three most common direct methods for measuring fiber-matrix adhesion, focusing on the sample preparation and fabrication, the experimental protocols and the underlying theoretical analyses upon which evaluation of these methods are based. In addition, finite-element nonlinear analyses and photoelastic analyses will be used to identify differences in the state of stress that is induced in each specimen model of the three different techniques. In order to provide an objective comparison between the three different techniques to measure the interfacial shear strength for the prospective user, data and a carbon fiber-epoxy resin system will be used as a baseline system throughout this chapter, However, these methods and procedures can be applied for adhesion measurements to any fiber-matrix combination. [Pg.613]
