Abstract

This project refers to the processing of thermoplastic composites from carbon fibers treated by plasma-assisted techniques. The treatments that are going to be employed are: the Dielectric Barrier Discharge (DBD), that is performed in atmospheric pressure, involving smaller energies and the Plasma Immersion Ion Implantation (PIII), which is held at sub atmospheric pressure, involving higher energies. After the treatment, treated and untreated samples are going to be characterized for comparison purposes and to check which treatment is more effective in obtaining better physico-chemical properties of the carbon fiber. Several characterization techniques will be used, such as Scanning Electron Microscopy (SEM), Raman spectroscopy, X-ray Photoelectron Spectroscopy (XPS) and Atomic Force Microscopy (AFM). Some analysis in the final composites will be carried out as well, such as interlaminar shear test, DMA analysis and vibration. (AU)
