Woven carbon fiber reinforced rubber laminated composites (WCRLC) are increasingly adopted in impact-critical engineering applications such as marine fenders and aerospace buffers, owing to their lightweight and energy absorption/reflection capabilities. However, dynamic mechanical response evaluation of WCRLC under high strain rates remains inadequately characterized. In this study, WCRLC was fabricated using silicon rubber and 2D woven carbon fiber (WCF) with the needled technique. Dynamic mechanical response and energy evolution of WCRLC were investigated using a split Hopkinson pressure bar (SHPB). The results showed that the stress at both ends of the specimen was in a state of dynamic equilibrium. The peak compressive strength and toughness of WCRLC increased with an increase of strain rate. The energy analysis indicated that with the increase of the number of layers of WCF, WCRLC demonstrated better impact resistance performance including the dynamic toughness, the energy absorption, specific energy absorption, and dissipated to incident energy ratio. Transmitted energy ratio of the five types of WCRLC was less than 1%. The WCRLC with 3 layers of WCF exhibited the highest transmission energy ratio due to balanced fiber-matrix interaction.

The centrifugal casting process of 6082 Al alloy was simulated by ProCAST software. The effects of rotation speed and heat transfer coefficient on the filling and solidification behaviour were analysed. The porosity of the cast pipe increases with the increase of the rotation speed and decreases with the increase of heat transfer coefficient. The CAFE model was used to simulate the grain structure of centrifugal cast Al alloy under different process conditions. When the rotation speed and heat transfer coefficient increase, the length of columnar crystal region will increase and the grain will be refined.

The reduction stripping kinetics of Ce⁴⁺ by HEH/EHP was studied by a constant interfacial area cell with laminar flow. The effects of stirring speed, temperature, specific interfacial area, Ce⁴⁺ concentration in the organic phase, free extractant concentration in the organic phase, HCl concentration, and H₂O₂ concentration on the stripping rate were investigated. The control mode and control steps of stripping process were judged. The kinetic equation of stripping was derived. The mechanism of stripping process was discussed. The results show that the stripping process is controlled by both diffusion and interfacial chemical reaction. The apparent activation energy E_a was calculated using Arrhenius’s formula. The kinetic equation of Ce⁴⁺ reduction stripping is R = k[Ce⁴⁺]_(o)^1.08[HEH/EHP]_(o)^−1.03[H⁺]_(a)^0.99[H₂O₂]_(a)^0.53, and the apparent rate constant k is 10^−3.66 (mol^−0.57·L^0.57)/min.
