Novel carbon fiber/epoxy composite toughened by electrospun polysulfone (PSF) nanofibers was prepared to enhance fracture toughness of the composite, and compared the morphology and toughness to those of composite toughened by PSF films prepared by solvent method. Polysulfone nanofibers with the average ...
Carbon fibers with both degradable epoxy resins as a sizing agent showed improved adhesive properties compared with the desized carbon fibers. Using the degradable sizing agent-applied carbon fibers, carbon fiber-reinforced plastics (CFRPs) were prepared by laminating prepreg sheets and heating them ...
It was hoped that by introducing one or more of these functional groups they would chemically interact with the epoxy resin promoting bonding between fiber and resin. In most cases an increase in the surface functionality is accompanied by an increase in surface area and so the relative ...
Carbon fiber reinforced plastic self-resistance electric (SRE) heating has been conceived as an alternative to out-of-autoclave technology due to its characteristics of uniform heating, fast heating/cooling, low energy consumption, and low equipment investment. In this work, a series of SRE heating...
Structural health monitoring for carbon nanotube (CNT)/carbon fiber/epoxy composite was verified by the measurement of electrical resistivity. This study has focused on the preparation of carbon nanotube composite sensors and their application for structural health monitoring. The change of the electrical...
F The fracture morphology at the interface between the fiber and matrix was also observed. The results have shown that the mechanical properties depend on temperature. The tensile modulus of the AS7J carbon/epoxy laminate increased as the temperature decreased, however, the tensile strength showed ...

16 CONCLUSIONS PTC effect of the epoxy resin filled with short carbon fibers is studied. The main reason of PTC was supposed to be a breaking off of inter-fiber contacts. In the composite with higher content of CF, there is smaller inter-fiber distance and because of this the greater ...
In conclusion, we demonstrated the microfabrication of electrically conductive polymer. Further, we investigated the electrical and mechanical properties as well as the carbon fibers dispersion of carbon fibers/PDMS composites for varying carbon fiber weight ratios. SEM analysis shows that the carbon fiber...
