“…These polar oxygen‐containing functional groups such as C─OH, ─COOH were beneficial to the increase of interfacial properties of composites, and the reason was that oxygen‐containing functional groups were significant for the form of bond between resin and CFs . As shown in Figure , the peak of molecular skeleton was main peak in every kind of CFs, which could be explained by the production process of CFs . The content of polar oxygen‐containing functional groups in T300 (49.97%) was more than that in T700 (20.75%), which may lead to the increase of interface performance for composites from T700 to T300 and it would be discussed later.…”

The interface between carbon fibers and resin has a great effect on the mechanical properties of composites, and acts as a bridge for the transportation of load between fibers and resin. The traditional measurement method for interfacial shear strength (IFSS) relies mainly on single‐fiber fragmentation test, which is not suited for opaque composites. In this article, a new method for measuring the interfacial shear strength of opaque resin/carbon fibers was firstly put forward. We used mapping from energy dispersive X‐ray spectroscopy (EDS) which replaced the polarizing microscope to detect the breakpoints of samples after being stretched. We found that the value of IFSS for composites made by carbon fibers and epoxy resin detected by traditional method and new method was similar, which indicated single‐fiber fragmentation test based on mapping from EDS was accurate. The value of IFSS for composites made by carbon fibers and epoxy resin modified by carbon nanotubes was measured by mapping from EDS, which indicated the wide applicability in opaque composites. The single‐fiber fragmentation test based on mapping from EDS made the IFSS measurement of opaque composite become possible, which made a great progress compared with traditional method.

“…As it is well known, the carbon ber has a broad peak at 2q of 25.6 , which is attributed to the lattice plane of graphitized carbon (002). 32,33 It was evident that the diffraction peaks of anatase TiO 2 (101) and carbon ber (002) were coincident. In addition, it was reported that the changes in diffraction peak at about 25.6 in TiO 2 @CNFs composites mainly resulted from the enhancement in degree of graphitization of CNFs.…”

“…The peaks observed in both spectra at approximately 1330 cm -1 and 1597 cm -1 are corresponding to the D and G peak, respectively. The D peak is activated by the defects or disorders of the graphitic lattices whereas the G peak is corresponding to the stretching vibrations of the graphitic structures due to the sp 2 phase [10][11][12][13]. The I d /I g ratio is a factor that correlates the intensity of the aforementioned peaks and gives information regarding the fiber microstructure heterogeneity and therefore can be an indication of surface defects [14].…”

The aim of the present study is the development of new composite materials that show improved mechanical and structural integrity. In order to accomplish this goal, a novel functionalization method of the carbon fibers for the reinforcement of the composites surface was investigated. Through the electrografting of methacrylic acid onto the surface of the carbon fiber, this treatment aims to selectively modify the surface of the carbon fabrics, in order to create active groups that can chemically react with the epoxy resin, under heat and pressure. By this way, better adhesion as mechanical interlocking between the resin and the reinforcement can be achieved. The surface treatment was examined qualitatively by means of Infrared spectroscopy, Scanning Electron Microscopy and Raman spectroscopy. The carbon fiber reinforced polymers were manufactured via the hot-press technique and they were subsequently submitted to flexural, shear and nanoindentation test. Finally, the internal structural integrity was tested through micro-Computing Tomography.
