preparation of Carbon Fiber unsaturated sizing agent for enhancing interfacial strength of Carbon Fiber vinyl ester resin composite
Applied Surface Science, 2018Co-Authors: Weiwei Jiao, Fan Yang, Long Jiang, Weicheng Jiao, Rongguo WangAbstract:Abstract The practical application of Carbon Fiber (CF) reinforced vinyl ester resin (VE) composite was hampered seriously by the poor interfacial adhesion property. In this work, a novel unsaturated sizing agent was designed and prepared to improve the interfacial strength by covalently bonding CF with VE matrix. The main component of the sizing agent, N-(4′4-diaminodiphenyl methane)-2-hydroxypropyl methacrylate (DMHM), was synthesized and confirmed by FTIR and NMR. XPS results of sized Carbon Fiber (SCF) showed that DMHM has adhered to desized Fiber surface and reacted with some active functional groups on the surface. The SCF was characterized by high surface roughness and surface energy (especially the polar component), which means better wettability by VE. As a result, the interface shear strength and interlaminar shear strength of SCF/VE composite were enhanced by 96.56% and 66.07% respectively compared with CF/VE composite, benefited mainly from the strong and tough interphase.

the effect of triangle shape Carbon Fiber on the flexural properties of the Carbon Fiber reinforced plastics
Materials Letters, 2012Co-Authors: Rongguo Wang, Zhanjun WuAbstract:Abstract The triangle-shape Carbon Fiber reinforced plastics and the round-shape Carbon Fiber reinforced plastics were manufactured and the effects of Carbon Fiber shapes on the flexural properties were investigated. The microstructures and the cross-section areas of the round-shape Carbon Fiber and the triangle-shape Carbon Fiber were discussed. As a result, it was found that the triangle-shape Carbon Fiber reinforced plastics showed higher flexural strength and flexural modulus than round-shape Carbon Fiber reinforced plastics, and the tensile strength and tensile modulus did not reduced, which was attributed to that the triangle-shape Carbon Fiber reinforced plastics had larger interfacial contact area than round-shape ones, and the wider interfacial contact area between reinforcement and matrix that could effectively transfer the applied load. The flexural properties of Fiber reinforced plastics were improved due to the stronger interfacial binding force.

preparation of a Carbon nanotube Carbon Fiber multi scale reinforcement by grafting multi walled Carbon nanotubes onto the Fibers
Carbon, 2007Co-Authors: Xiaodong He, Fuhua Zhang, Rongguo WangAbstract:Abstract To prepare a Carbon nanotube (CNT)/Carbon Fiber multi-scale reinforcement (MSR), multi-walled Carbon nanotubes (MWCNTs) functionalized at the end caps with hexamethylene diamine (HMD) are grafted onto the surfaces of Carbon Fibers treated with acyl chloride. The surface element concentrations, surface functional groups and morphology of the MSR were examined by X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM). XPS spectra indicate that sp2 and sp3 Carbon atoms are major components in the MSR surface, and the Carbon Fiber surface structure is not destroyed. There is 17.41% of C–NHx in the surface of the MSR, which suggests that MWCNTs are covalently grafted onto Carbon Fiber surfaces. SEM shows that the grafted MWCNTs stick to the Carbon Fiber surface at different angles, and are uniformly distributed along the outer edges of the grooves in the Fiber surface. The grafted MWCNTs are 50–200 nm in length and around 14 nm in diameter. It was found that the grafting increases the weight of Carbon Fiber by 1.2%, which implied that a considerable amount of MWCNTs were grafted onto Carbon Fiber surfaces.
