“…As a result, the networks of the clay/ epoxy are not synthesized homogeneously and tightly as those of the pure epoxy resin (Harsch et al, 2007). The presence of the clay causes an increase in viscosity, lowers the mobility of the reactive species, and results in a lower total enthalpy (ΔH) in the epoxy/clay system compared with the pure epoxy resin (Table 1).…”

“…This process mainly defines the network structure and, consequently, the final properties of a composite [2]. As an example, strong residual stresses can be generated during curing as a consequence of the thermal and mechanical mismatches between the constituent phases of the composite.…”

Abstract.A study on free nanohole volumes in particulate epoxy matrix composites as a function of the aluminum particles content is presented. Specifically, the influence of the filler content in the epoxy matrix on the nanohole volume is analyzed in terms of the mechanical and morphological properties of the composites fabricated. Nanoholes data were measured using positron annihilation lifetime spectroscopy recently published by the authors. Applying the Park-Earmme micromechanical model, these data are interpreted in terms of the thermal stresses generated during the curing process applied during fabrication. Some input parameters of the model were experimentally obtained. In order to obtain a satisfactory description of the evolution of the free nanohole volume in the whole range of filler contents, a contribution due to the matrix-particle interphases is taken into account in the micromechanical model. To this aim, specific information on the interphases was obtained using atomic force microscopy (AFM), scanning electron microscopy (SEM), differencital scanning calorimetry (DSC) and a free-constraint analysis of the positron lifetime data.

“…The mechanical properties of epoxy resins can, however, be improved by incorporating inorganic particles [1]. It is well known that particle volume, shape, size, surface characteristics and particle dispersion within the matrix have an influence on the mechanical properties of the composites [2][3][4][5].…”

Abstract. The effect of fumed silica on the curing of a trimethylolpropane epoxy resin was investigated by thermal analysis methods like Differential Scanning Calorimetry (DSC), and Dynamic Mechanical Analysis (DMA). The fumed silica used here is a by-product of the silicon and ferrosilicon industry, consisting of micro and nanosized particles. Both the curing reaction and the properties of the obtained composites were affected by the filler content. Different trends were observed for filler contents above and below the 30 wt%. Up to 30 wt%, the behaviour can be explained as a predominantly agglomeration effect. For 30 wt% and higher filler contents, single particles seem to play a more important role.
