Research on the Quality of Fiber-Reinforced Composites
Applied Mechanics and Materials, 2018The paper aims an experimental study of the quality of composite materials based on the coefficient of uniformity, an indicator that appreciates the influence of different factors on their mechanical behavior. For the experiment, composite plates having an epoxy resin matrix and various types of reinforcement were made.

Cotton Breeding for Fiber Quality Improvement
2014Cotton (Gossypium hirsutum L.) is the world’s leading fiber crop, grown or processed in many countries, providing a major contribution to their economies. Yield is economically most important to a producer which drives cultivar development and adoption; however, fiber quality is the primary focus for spinning mills. Cotton fiber quality must improve to

The quality of cotton fiber : a new challenge
1997Spinning machinery is increasingly automated and rapid. The resulting fall in processing costs means that the starting material has become the principal component in the yarn cost. In addition, the spinning process and the quality of the finished product are dependent upon the characteristics of the fiber supplied.

Improving the beam quality in LMA fibers
SPIE Proceedings, 2008The paper presents the results concerning with beam quality improvement by concurrently modifying the index and the doping profile in LMA fibers. Further, the mode effective area is maximized by providing a passive ring in the cladding. The influence of the index profile over the distribution of the optical power among various modes is presented.

Variability of cotton fiber quality
2000Fiber quality variability is one of the key determinants of the profitability of the cotton crop. As this variability increases, the risk associated with production increases and the expected return decreases. Prior to our studies, variability had been characterized at the field or crop lever.

Analysis of the variability of fiber quality
1997Les recherches menées au CIRAD de 1995 à 1996 ont visé à caractériser la variabilité de la qualité de la fibre de coton. Un modèle de décomposition de l'index de la fibre est proposé pour mettre en rapport la production et la qualité de la fibre. Cette approche est exposée dans ce document en présentant les relations qui ont été établies entre le ...

QUALITY OF MODIFIED FLAX FIBERS
2007When polycarboxil acid affects cellulose, a chemical modification of molecular and also of super molecular fiber structure occurs, making natural fibers modified in such a way that they become interesting for use in new textiles where they can substitute man-made materials on an equal basis. In this paper a chemical modification of flax fabric has been
