X-ray computed tomography (CT) techniques have been used to evaluate a structural index of high performance metal matrix composites (MMC). Beside of classical features like the determination of number of fibres and eccentricity of fibre bundles an order parameter can be defined and demonstrated for the SiC fibre arrangement in Ti-MMC, which can be used to assess these materials. The samples for...

1.0 Introduction It is now reasonably well established that reinforced concrete (RC) structural elements can be strengthened/retrofitted/repaired by bonding high-strength fibre reinforced polymer (FRP) composites. Such reasons include steel reinforcement corrosion, construction flaws, change in loading or structure usage, or damage from impact or seismic events. Traditional methods of repair ca...

In a fibre-reinforced polymer (FRP) structure designed using the emerging damage tolerance and structural health monitoring philosophy, sensors and models that describe crack propagation will enable a structure to operate despite the presence of damage by fully exploiting the material's mechanical properties. When applying this concept to different structures, sensor systems and damage types, a...

The present study deals with the finite element modelling of control RC slabs and strengthened slabs with the help of ANSYS. ANSYS is software that is based on FE method in which modelling of RC structures is done. In this study, a control slab was modelled and the results were analysed and then strengthened slabs were modelled and analysed. The results of the control and strengthened slabs wer...

Lightweight design, using high performance composites, which directly yields a reduced need for fuel is in the focus of new developments for traffic engineering. The increased substitution of traditional, metal based materials by fibre-reinforced composites in the aviation industry exemplifies this trend. In addition to mechanical properties, e.g. an increase in strength, that leads to direct w...

-This paper presents the compressive strength of PET fibre reinforced recycles aggregate concrete. The Natural Aggregate (NC) was replaced by recycle aggregate (RA) in the proportion of 25, 50, 75 and 100%. PET fibres were added to the Recycle Aggregate Concrete (RAC) by 1 and 2% volume. Total 45 cubes were cast and tested. The results showed that as the % of RA and volume fraction of PET fibre...

Fibre reinforced plastics are increasing their importance as one of the most interesting groups of material on account of their low weight, high strength and stiffness. To obtain good quality holes, it is important to identify the type of material, ply stacking sequence and fibre orientation. In this paper, the drilling of quasi-isotropic hybrid carbon+glass/epoxy plates is analyzed. Two commer...
