Oxide/oxide composites are being considered in the aerospace industry for design of next-generation exhaust components. This study aims to determine mechanical behaviour a composite consisting Nextel™610 fibres fabric (8 HSW) embedded porous alumina matrix. The properties were studied tension and four-point bending up 1300 °C. Up 800 °C, material is elastic exhibits few damage with only low eff...
the effect of the presence of perforations on he stresses of a plate is a problem which is of great interest in structural design and in the mathemattical theory of elasticity. among the many hole patterns that are likely to require consideration is the ring of equally spaced circular holes. the present worke investigates stress & strain analysis of a thin isotropic circular plate containing a ...
2010 KTH accounts for one-third of Sweden's technical research and engineering education capacity at university level. Education and research cover a broad spectrum – from natural sciences to all the branches of engineering. Part of this work was performed a Innventia AB. Innventia AB is a world leader in research and development relating to pulp, paper, graphic media, packaging and biorefining...
The superminimality of the fibres of an almost contact metric submersion is used to study the integrability of the horizontal distribution and the structure of the total space.
Ammonia is a weak base that can be used as an swelling agent on wool fibres before dyeing. In this study the pretreatment of wool with ammonia in different percent solutions (5, 10, 15, 20) is carried out, and its effect on dye-ability of wool by natural dyes such as madder, walnut shell, pomegranate peel, vine leaf, white and red onion skin, is analyzed. Also the effects of temperature, length...
Living matter offers many examples of what appears to be action exerted at a distance. I am not attempting to renew the discussion of the classical problem of physics because the action at a distance which I have in mind is not exerted through vacuous space but through matter, and its peculiarity lies in the fact that the intervening matter seems to act in a purely passive way. The example whic...
Flax (Linum usitatissimum L.) is an annual plant cultivated mainly for its fibres. Although the whole genus contains about 230 species, only L. usitatissimum retains an important commercial use, serving as a fibre source for the textile industry. Flax fibres are less elastic than cotton fibres, and thus their use in textile production is more limited. However, the climate and soil quality in ce...
Plant-derived natural fibres hold great potential as renewable and sustainable reinforcing elements in structural composites. However, a broader use of fibre composites requires further improvements their mechanical properties, to reach performance comparable carbon fibre-reinforced polymers. In this study, we exploit discontinuous rheologically modified inks controllably reinforce flax-based l...
