The incorporation of graphene nanoplatelets (GNPs) as nanoreinforcement in multiscale composite materials has become increasingly interesting for structural health monitoring. The GNPs create an electrically conductive network through the composite material, which is susceptible to dimensional changes. Additionally, the presence of discontinuities i.e. cracks or delaminations, causes the breaka...

This paper studies the fracture behaviour of unidirectional carbon fibre reinforced carbon matrix composites and its relation with the type of fibre-matrix interface developed in the composite. Model unidirectional carbon-carbon composites were prepared using the same type of fibre and different pitches as matrix precursors. These included both commercial pitches and synthesized in the laborato...

The existing experimental evidence suggests that organic matrix composites sustain less impact damage when an electric field is applied. The intricate interaction of an electrical field and mechanical load is governed by coupling of the mechanical and electromagnetic fields via the Lorentz force as well as by the processes undergoing at the microscopic level: Joule heat, fiber-matrix interface ...

If the electrical resistance of a material depends upon external straining, the material exhibits ‘piezoresistivity’. The piezoresistive behavior has been realized in an electrically conductive elastomer composite where the microstructure of conductive fillers can be changed under finite deformation of elastomer, resulting in the change of the composite resistivity. In this paper, we analyze th...

Carbon nanotubes (CNT) are attractive next generation materials due to their unique properties, which lead to high mechanical, electrical, and thermal performance (Iijima, 1991; Endo et al., 1976; Niyogi et al., 2002; Komarov & Mirnov, 2004). This unique nano order material can not only be utilized on its own in precision industrial fields but can also provide high performance functionality in ...

The preparation of thin composite layers has promising advantages in a variety of applications like transdermal, buccal, or sublingual patches. Within this model study the impact of the matrix material on the film forming properties of ibuprofen-matrix composite films is investigated. As matrix materials polystyrene, methyl cellulose, or hydroxyl-ethyl cellulose were used. The film properties w...
