摘要：
Three types of commercially available organophilic Montmorillonite (Cloisite 30B, 25A and 15A) were used to prepare VARTM epoxy resin nanocomposites in order to study the effect of the nanoclay organophilic modification on the epoxy matrix. The morphology of the dispersions was investigated through XRD and TEM analyses. The thermal stability of the nanocomposites was studied by means of HI-RES TG measurements and the influence of the nanoclay on the viscosity of the resin was investigated through rheological measurements. It was found that the nanoclay modification had no significant influence on the dispersion and on the thermal properties of the nanocomposites. Areas of exfoliated and intercalated morphology were observed. The viscosity of the resin furthermore did not exceed the critical value of the infusion process.
