Effects of the Potassium Titanate Functional Filler Types on the Thermal Protection Performance of Heat Resistant Ablative Coated Fabrics
Nano, 2018Co-Authors: Guoyi Liu, Yuanjun Liu, Xiaoming ZhaoAbstract:Considering sub-micron potassium titanate whiskers (BX-101), nanoscale potassium titanate whiskers (AX-301), sub-micron potassium titanate whiskers (AX-316) and high strength potassium titanate crystal (AX-319) as Functional Fillers, heat resistant ablative coated fabrics which have high radiant heat reflectivity were prepared. The effect of the type of Functional Filler on the thermal protection performance of heat resistant ablative coated fabrics was mainly discussed. Research showed that the microstructure of potassium titanate Functional Filler had a significant impact on the radiant heat reflectivity and thermal insulation performance of the prepared coated fabric. The coated fabric which took nanoscale potassium titanate whiskers (AX-301) with a minimum diameter and greater length-diameter ratio as Functional Filler has the highest thermal reflectivity and the best insulation property. Heat ray reflectivity of potassium titanate coated fabrics had positive correlation with their crystallinities. The higher the coated fabric crystallinity was, the greater the heat ray reflectivity. Thermogravimetric analysis results showed that after adding four kinds of potassium titanate Fillers, the thermal stability of the prepared coated fabrics was enhanced, and the nanoscale potassium titanate whiskers (AX-301) coated fabrics had the best thermal stability.

gamma ray shielding property shielding mechanism and predicting model of continuous basalt fiber reinforced polymer matrix composite containing Functional Filler
Materials & Design, 2017Co-Authors: Ran Li, Yizhuo Gu, Zhongjia Yang, Min Li, Zuoguang ZhangAbstract:Abstract Functional shielding Filler modified fiber reinforced polymer matrix composites are novel structural/radiation shielding materials with great potentials in applications such as nuclear industry and radioactive therapy. In this study, unidirectional basalt fiber reinforced epoxy resin matrix composite laminates containing different contents of tungsten (W) and erbium oxide (Er2O3) Fillers were fabricated. Experimental measurement and theoretical calculation of mass attenuation coefficients of γ ray were carried out and analyzed based on photon shielding mechanism. The effects of Filler content and photon energy of γ ray on shielding property of composite were studied. It is found that adding W and Er2O3 Fillers significantly increases mass attenuation coefficient of basalt fiber composite, especially for low photon energy. The discrepancy between measured and calculated results is obvious at low Filler content, and is believed to come from different considerations on penetrating photons, which have undergone slight Compton scattering. The corresponding mechanism was discussed. An empirical model based on photoelectric absorption effect, Compton scattering effect and effective atomic number is established to modify calculated mass attenuation coefficient. A good accuracy was validated, so the model can be used to design this kind of composite for better shielding ability.
