Natural fibres were initially used in composite materials to predominately improve bulk and reduce cost rather than improving mechanical properties. But the environmental problems associated with the production and use of synthetic fibres have changed the scenario. In the previous decade, natural fibres have been extensively used as reinforcement materials for both synthetic and bio-degradable matrices. Natural fibre reinforcements have mostly improved flexural and impact properties, but tensile strength improvement has been marginal and has been an area of investigation. Many attempts have been made towards improving mechanical properties, with efforts directed at improving the interface, newer methods of production of composites, new modelling techniques etc. In this detailed review, an attempt is made to critically analyse the various research efforts directed towards improving the mechanical properties of natural fibre reinforced composites. 相似文献

The pulps of agricultural products used industrially in Isparta (Turkey) which contain natural dye pigments were used to obtain low-cost natural dyes. Natural dyes were obtained with the extraction method from the pulps of lavender and Spartium junceum flowers after oil extraction and the pulp of Dimrit grape red wine. The dyeing of wool yarns with these compounds as a natural dye has been studied and ecological wool dyeing achieved by using nontoxic and ecological mordants. Natural dyes optimum extraction times were analyzed. Dyed wool yarns washing, rubbing, and light fastness tests and spectrophotometric measurements were performed. In addition, wastewater analysis were achieved and cost estimates of natural and synthetic dyeing methods were evaluated and compared. 相似文献
