Title

Measuring Tensile Stresses In Cnf/Polymer Composites Using Raman Spectroscopy

Abstract

This research focuses on developing relationships between the mechanical properties and the optical spectra of carbon nanofiber (CNF) reinforced polymer composites. Stress distribution in the sample at discrete force increments is obtained and the effects on the G band of the Raman spectra of CNF are observed. A linear shift of carbon nanofiber Raman frequencies is created by strain applied to their molecular structure. Results of loading experiments combined with optical spectroscopy shows the stress dependency of these bands which can be used in the future for design, analysis and non-destructive structural stress testing of CNF/polymer composites.
