As the widely used resin matrix and composites, two kinds of epoxy matrix and its CF/epoxy composite and GF/composite have different mechanics property under different temperature. The result shows that the thermal property of the composite mainly depends on the matrix. If the matrix can resist high temperature, its composite can also have high strength under high temperature. resin matrix composite, thermal resistance, thermal deformation coefficient, severity retentivity ratio

It was found that sulfuric acid, 2-naphthalenesulphonic acid and sulfurous acid could be effectively separated by competitive exchange adsorption in views of action force difference of the components with the resin. The exchange adsorption dynamic diffusion parameters were calculated with diffusion equation for solids and liquid films, and the rate-determining step was determined. The model of breakthrough curve for the resin bed was suggested, and applied to simulate the breakthrough process for each component.

The effect of flow rates, initial concentrations, resin bed heights, its height/ diameter ratios and temperature on breakthrough curves of sulfuric acid/2-naphthalenesulphonic acid, 2-naphthalenesulphonic acid/sulfurous acid and sulfuric acid/ 2-naphthalenesulphonic acid/sulfurous acid systems was investigated. Excellent agreement was obtained between experimental data and the suggested breakthrough data model, with which the breakthrough curves can be accurately predicted for multi-component adsorptive separation in resin bed, the experiment of adsorptive separation may be scaled up, and the plant may be designed.
