A nanostructured cellulose-based interphase layer to enhance the mechanical performance of glass fibre-reinforced polymer composites

چکیده

In this study, we report the effect of sizing glass fibres (GFs) with tetramethylpiperidine-1-oxyl (TEMPO)-mediated cellulose nanocrystals (t-CNC) to improve interfacial mechanical performance fibre reinforced polymer composites (GFRP). These nanoparticles are introduced at different concentrations yield a coating t-CNCs which (1) sparsely deposited low concentrations, and (2) uniformly self-assembled over higher concentration. The mechanical, morphological interphase results show that CNC around provides better strengthening than CNCs. Experimental confirmed GFs coated yielded ~30% increase in interlaminar shear strength (ILSS), 43% flexural 40% modulus GFRP composite. Strong nanoscale interactions between t-CNC GF, coupled formation high gradient layer, contributed significant improvement t-CNC/GFRP composites.

Three-dimensional nonlinear micro/meso-mechanical response of the fibre-reinforced polymer composites

A three-dimensional multi-scale computational homogenisation framework is developed for the prediction of nonlinear micro/meso-mechanical response of the fibre-reinforced polymer (FRP) composites. Two dominant damage mechanisms, i.e. matrix elasto-plastic response and fibre-matrix decohesion are considered and modelled using a non-associative pressure dependent paraboloidal yield criterion and ...

Self-healing of damage in fibre-reinforced polymer-matrix composites.

Self-healing resin systems have been discussed for over a decade and four different technologies had been proposed. However, little work on their application as composite matrices has been published although this was one of the stated aims of the earliest work in the field. This paper reports on the optimization of a solid-state self-healing resin system and its subsequent use as a matrix for h...
