TL;DR: In this article, an epoxy resin was cured while in intimate contact with small amounts of epoxy-pharmic montmorillonites, and it was determined that cured epoxy exists within the Montmorillonite interlayer by the observation of very high interlayer spacings, even greater than 8 nm.
Abstract: An epoxy resin was cured while in intimate contact with small amounts of epoxyphilic montmorillonites. It was determined that cured epoxy exists within the montmorillonite interlayer by the observation of very high interlayer spacings, even greater than 8 nm, Generally, epoxy compounds containing montmorillonites that had been swollen in the curing agent prior to curing exhibited larger interlayer spacings, especially among the non-dispersed montmorillonite layers. The maximum observed residual stress was reduced by greater than 50% in the epoxyphilic montmorillonite/epoxy compounds over that of the pure epoxy. The epoxyphilic montmorillonite/epoxy compounds generally exhibited higher values of glass transition temperature, flexural modulus, and ultimate flexural strength than the pure epoxy. The tyramine-montmorillonite compounds typically had the highest values overall.

TL;DR: A study on the flexural properties of hybrid composites reinforced by S-2 glass and T700S carbon fibres is presented in this article, where failure modes are examined under an optical microscope, and the results show that the dominant failure mode is compressive failure.
Abstract: A study on the flexural properties of hybrid composites reinforced by S-2 glass and T700S carbon fibres is presented in this paper Specimens were manufactured following the hand lay-up process in an intra-ply configuration with varying degrees of glass fibres added to the surface of a carbon laminate These specimens were then tested in the three point bend configuration in accordance with ASTM D790-07 at a span to depth ratio of 32 The failure modes were examined under an optical microscope, and the results show that the dominant failure mode is compressive failure The flexural modulus, flexural strength and strain to failure were also predicted by finite element analysis It is seen that flexural modulus decreases with increasing percentage of S-2 glass fibres Both the experiments and FEA suggest that positive hybrid effects exist by substituting carbon fibres with glass fibres

TL;DR: In this article, three MAPP couplers with different molecular weights and maleic anhydride contents were considered and the effects on the mechanical properties of the composite were studied, and scanning electron microscopy was used to study the fracture morphology of the tensile specimens.

TL;DR: In this article, the authors studied the impact and fracture properties of hollow-glass micro-sphere/epoxy resin composites in terms of fracture toughness, fractography, flexural properties and impact force.
Abstract: Fracture and impact behaviours of hollow-glass micro-sphere/epoxy resin composites are studied in terms of fracture toughness, fractography, flexural properties and impact force. Volume fraction of micro-spheres for the composites was varied up to 0.65. The addition of micro-spheres did not enhance the specific fracture toughness of the composites despite the presence of a pinning mechanism at relatively low volume fractions. Performance in reducing the impact force was enhanced as the content of micro-spheres increased, but at the expense of other properties such as specific fracture toughness and specific flexural strength, while specific flexural modulus marginally increased at some high volume fractions of micro-spheres.
