Instrument for Measuring Precisely the Cross-Sectional Area and Axial Young's Modulus of Single Carbon Fiber by Resonance Method with Contactless Detection System

摘要

The instrument the authors developed can measure precisely the cross-sectional area and Young's modulus of single carbon fiber of any cross-section form, without defects in other methods, by adopting the techniques of contactless detection and amplification, and the vacuum system applied to it. The advantages of resonance method are brought into full play.
