Ablation Resistance

The effect of SiBCN powder on properties of phenolic resins and composites was analyzed. Compared with phenolic resins, the thermal stability of SiBCN powder modified phenolic resins (the SiBCN phenolic resins) by characterization of thermogravimetric analysis (TGA) improved clearly. It was found by X-ray photoelectron spectroscopy (XPS) that reactions between SiBCN powder and the pyrolysis product of phenolic resins were the main factor of the increased residual weight. TGA and static ablation of a muffle furnace were used to illustrate the roles of SiBCN powder on increasing oxidation resistance of SiBCN powder-modified phenolic resin–carbon fiber composites (SiBCN–phenolic/C composites), and the oxidative product was analyzed by X-ray diffraction (XRD), scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR). For SiBCN–phenolic/C composites, the occurrence of oxidation reaction and the formation of protective crust contributed to improving oxidative resistance. The result of the oxygen-acetylene test showed that the linear ablation rate (LAR) and mass ablation rate (MAR) of phenolic resin–carbon fiber composites reduced from 0.052 ± 0.005 mm/s to 0.038 ± 0.004 mm/s and from 0.050 ± 0.004 g/s to 0.043 ± 0.001 g/s by introducing SiBCN powder, respectively. The mechanism of ablation resistance after the introduction of SiBCN powder was investigated. The high melt-viscosity of SiBCN powder caused SiBCN powder to remain on the surface of composites and protect the internal resins and carbon fibers. The oxidation of SiBCN powder and volatilization of oxide can consume energy and oxygen, thus the ablation resistance of SiBCN–Ph composite was improved.

In our previous study we showed the the potential of using of sub-micro Alumina/Titanium (ALTi) particles as a multifunctional reinforcement which can produce multifunctional polymer composites. This paper aims to investigate the interfacial shear properties for different contents of ALTi particles incorporated into PA6 with de-sized carbon fiber. By means of X-ray photoelectron spectroscopy (XPS), activated carbon atoms can be detected, which are defined as the carbon atoms conjunction with oxygen and nitrogen. Sizing removal can reduce the acid parameter of carbon fibers surface promoting bonding strength at the fiber/matrix interface which is a desirable property for the carbon fiber composites. XPS also, showed that epoxide group still appeared with using acetone treatment while disappeared with conventional heating at the oven for 25min ate 450oC. SEM images did not show any damage for the carbon fiber after heat treatment. Interfacial shear strength (IFSS) showed an improvement in interfacial adhesion with de-sizing carbon fiber than neat PA6.

Four kinds of TiO2/CNT (or carbon fiber) composites were successfully prepared by the sol-gel method using Ti(OBu)4 as precursor of TiO2, and untreated CNT, carboxylic CNT, hydroxylated CNT and carbon fiber were used as carriers, respectively. After heat treatment at 400 and 800°C, TiO2/CNT nanocomposites and purified TiO2 were obtained. Their structure and morphology were characterized by X-ray diffraction (XRD) and scanning electron microscope (SEM). The results indicate that different carbon nanotubes and nanofiber have notable influences on the morphology and structure of TiO2 nanocrystals.
