TL;DR: In this paper, the properties of block copolymers were studied by SALS, dynamic mechanical testing, DSC, and stress-strain and dichroism experiments, and they provided a superstructure for the elastomer phase consisting of uncrystallized hard and soft segments.

TL;DR: In this article, the effect of nanoclay concentration on the cure behavior was investigated using an on-line dielectric cure monitoring technique using differential scanning calorimetry (DSC).
Abstract: Epoxy-clay nanocomposites were prepared with organically modified layered clay with varying clay contents (1–8 wt.%). Neat resin and nanocomposite were characterized using different techniques. At first, the effect of nanoclay concentration on the cure behaviour was investigated using an on-line dielectric cure monitoring technique. Differential scanning calorimetry (DSC) was used to verify the dielectric measurement results. Furthermore, mechanical and thermal properties were studied using tensile test and Dynamic Mechanical Analysis (DMA), respectively. Experimental results showed that properties of the epoxy were changed evidently because of the nanoclay loading. The tensile modulus of the nanocomposites increased by 47%, however, no improvement in tensile strength and glass transition temperature ( T g ) was observed. Fracture surface of the tensile samples were analyzed by Scanning Electron Microscope (SEM). The nanocomposites structures were characterized with Wide Angle X-Ray Diffraction (WAXD) and Transmission Electron Microscopy (TEM), which revealed the intercalated morphology of clay layers in the epoxy resin systems.

TL;DR: In this paper, the role of moisture penetration in composite materials is discussed and problems pertinent to the role and role of permeability of composite materials must be of prime consideration as limiting factors.
Abstract: The last few years have witnessed a tremendous growth in the use of composite materials in various fields, spanning the whole range from sporting goods to structural materials for the aerospace industry. Such applications almost invariably entail contacts with liquids or vapours—either aqueous or organic—bearing on both the immediate and the long-term performance of the material. Hence, problems pertinent to the role of permeability of composite materials must be of prime consideration as limiting factors. This applies particularly to the most common phenomenon of moisture penetration.
