Sol Gel Method

Alumina coating on carbon fibre were prepared by Sol-gel method, and characterized by thermal gravimetric analysis, X-ray diffraction and scanning electron microscopy. Affected factors such as coating times, oxidation temperature and time were investigated. The results show alumina coatings on carbon fibres are crack-free with a smooth surface, therefore would improve anti-oxidation of carbon fibre significantly. Thickness is one of the most important factors on anti-oxidation of alumina coating, and in this work, thicker coatings have better anti-oxidation quality.

A novel titanium dioxide （TiO2） nanoparticles coated carbon nanotubes (CNTs) composites were prepared by sol-gel method as microwave absorbing materials in this paper. SEM and XRD researches show that sol-gel method can realize uniform coating of CNTs with TiO2. Among them, with the weight fraction of TiO2/ CNTs composites was 10%, microwave absorption characteristics with a minimum RL value of -34 dB at 6.2 GHz on a coating with a matching thickness of 4mm and <−10 dB was obtained in the frequency range of 4.5-18 GHz with the thickness of 1.5-5.0mm.

This paper presents the Quasi Static Indentation (QSI) behavior of the chopped carbon fibre composites with three different loadings of nanoclay. The composites, which are Carbon fibre (CF), 1wt% Nanoclay–Carbon Fibre (1NC-CF), 3wt% Nanoclay–Carbon Fibre (3NC-CF) and 5wt% Nanoclay–Carbon Fibre (5NC-CF) were prepared using hand lay-up method. The nanoclay was dispersed using a three roll milling machine. The 10wt% of chopped carbon fibres with 3-5 mm length were used in fabricating these composites. The QSI test was conducted using Universal Testing Machine according to the ASTM D6264. The damage section was examined using optical microscopy. The results show that the energy absorbed was increased with addition of nanoclay up to 81.42 %, 137.69 % and 202.95 % for 1NC-CF, 3NC-CF and 5NC-CF composites, respectively. It was concluded that the addition of the nanoclay enhanced the QSI of chopped carbon fibres composites
