Carbon fibers (CFs) have a unique combination of properties which allow them to be widely used as reinforcing materials in advanced polymer composites. The mechanical properties of CF-reinforced polymer composites are governed mainly by the quality of interfacial adhesion between the CFs and the polymer matrix. Surface treatments of CFs are generally carried out to introduce chemical functional groups on the fiber surfaces, which provide the ability to control the surface characteristics of CFs. In this study, we review recent experimental studies concerning various surface treatment methods for CFs. In addition, direct examples of the preparation and properties of CF-reinforced thermosetting composites are discussed.

“…Here, the C 1 s peak was deconvoluted and found to divide into three distinct peaks. The peak at 284.6 eV corresponds to C-C or C-H bonds [28,29], while the higher oxidation states of carbon located at 286.7 eV correspond to C-O-H or C-O-C functional groups [28,29]. Finally, the peak at 288.5 eV is attributed to H-O-C=O or R-O-C=O groups [30,31].…”

Effect of Atmospheric Pressure Plasma Treatment on the Lap-Shear Strength of Adhesive-Bonded Sheet Molding Compound Joints

Atmospheric pressure plasma treatment (APPT) technology was used herein to treat sheet molding compound (SMC) substrates to increase the lap-shear strength of adhesive-bonded SMC joints. Further, the mechanisms behind the lap-shear strength improvements in APPT-treated adhesive-bonded SMC joints were explored. A maximum lap-shear strength about three times that of the as-received SMC joints was achieved when the APPT distance was set to 20 mm. The surface roughness, which exhibited little benefit to the lap-shear strength, was determined to not be the primary reason for the increase in lap-shear strength. Specifically, X-ray photoelectron spectra revealed that an increased amount of O-containing groups (i.e., C-O-H, C-O-C, H-O-C=O or R-O-C=O) following APPT contributed to the improved lap-shear strength. In addition, the surface free energy increased significantly after APPT, which improved the lap-shear strength of the adhesive-bonded SMC joints. Compared to the change of surface morphology, the changes in both the surface chemical property and surface free energy played larger roles in increasing the lap-shear strength of APPT-treated SMC joints.

“…Plasma activation can also ablate [40] and oxidise [41] the surface of treated polymers leading to morphological changes [42]. It was also considered that for longer treatment times and/or higher applied powers, ablation of the prepreg surface may occur and lead to the development of a weakened boundary layer.…”
