Interfacial Evaluation and Self-Sensing of Single Carbon Fiber/Acid-Treated CNT-Epoxy Composites using Electro-Micromechanical Technique |
| 초록 |
Interfacial evaluation and self-sensing were investigated for the acid-treated CNT/epoxy composites with different aicds and dispersive solvents. Acid-treated CNT might increase the chemical interaction without sacrificing electrical properties. Acid-treated CNT exhibited better dispersion and interfacial properties due to introduced functional group on CNTs. Apparent modulus and electrical contact resistivity for CNT/epoxy composites were evaluated as functions of different acid treated method. Apparent modulus of acid-treated CNT/epoxy composites was higher than the untreated CNT/epoxy case. The higher CNT concentration, the higher apparent modulus due to better stress transfer. Dynamic contact angle was measured for surface energy comparison. Acknowledgement: This work was supported by Defense Acquisition Program Administration and ADD under the contract UD070009AD.
