Mechanical properties of fibres

The mechanical properties of fibres and yams are quite complex and have been the subject of much experimental work. A stressed fibre is a very complicated viscoelastic system in which a number of irreversible processes, connected with plasticity, can take place. 

The most important mechanical properties of fibres and filaments are ... 

The theoretical treatment of the mechanical properties of fibres is, as a matter of fact, more complicated than that of isotropic polymers. Instead of two elastic parameters, e.g. the tensile modulus and the Poisson ratio, we now need five, because of the anisotropy. 

Effect of Relative Humidity on the Surface Area of Paper. Virtually all the physical and mechanical properties of fibres and paper vary strongly with moisture content, and it would be expected that surface properties should also be sensitive to relative humidity. Little work has been published on the effect of moisture on the surface properties of fibres and paper. As a starting point, it may be noted that the basic property of any surface is its surface area. How does the surface area of a fibre or paper sheet change with relative humidity ... 

Excellent mechanical properties of fibre-reinforced plastics (epoxy, PUR, phenolics) are... 

Thus, the E moduli slightly decrease, and are lower for coated fibres than for uncoated fibres. The mechanical properties of fibres coated at a r.f. power level of 600 W compared to that coated at 300 W change to lower values.

By far the greatest share of both experimental studies of mechanical properties of fibres and theoretical studies of structural mechanics has been on tensile properties. This paper therefore concentrates on explanations of tensile stress-strain curves and the way in which they lead to fracture. Some comments on other forces, particularly in cyclic loading, will be included in a concluding section. 

There are a number of published papers in the area of composites, probably exceeding those in the area of textiles themselves examples of a few recent pubUcations on the application of the homogenization method in modelling the mechanical properties of fibre-reinforced composites are Saidpour and Oscar (2006), Maimi et aL (2008), Massart et al (2011), and Melro et al. (2012).
