Abstract Since the last two decades, many researchers have refocused on using natural fibres, as reinforcements for cementitious and polymer based structural materials. The use of natural fibres for structural applications is not modern.

Repeatable patient positioning is key to minimising the burden on planning radiotherapy treatment. There are very few materials commercially available which are suitable for use in all common imaging and treatment modalities such as magnetic resonance imaging MRI , X-Ray computed tomography CT and radiotherapy. In this article, we present several such materials based on woven natural fibres embedded in a range of different resin materials which are suitable for such applications. These results demonstrate that natural fibre composites produced using such materials provide desirable properties for use in patient support and positioning devices for multi-modal imaging, without the need to significantly compromise on the strength of the material. As cancer treatments are becoming increasingly advanced, there is a growing demand for treatment plans to be based upon images from more than one imaging modality [ 1 , 2 ].

Advances in Natural Fibre Composites

Reviewed: October 24th Published: January 23rd Fibre-reinforced polymer FRP , also Fibre-reinforced plastic , is a composite material made of a polymer matrix reinforced with fibres. The fibres are usually glass, carbon, or aramid, although other fibres such as paper or wood or asbestos have been sometimes used. The polymer is usually an epoxy, vinylester or polyester thermosetting plastic, and phenol formaldehyde resins are still in use. FRPs are commonly used in the aerospace, automotive, marine, and construction industries. Composite materials are engineered or naturally occurring materials made from two or more constituent materials with significantly different physical or chemical properties which remain separate and distinct within the finished structure.

The natural and fiber-reinforced resin matrix composites have been increasingly and widely applied in society in order to improve the environment and promote sustainable development. In the first part of this article, the major foci of recent research on natural fiber composites are reviewed in detail, including fiber surface treatment, fiber agglomeration and dispersion, interfacial transcrystallinity, impact strength, foaming technique, inflaming retardance, biodegradable resin matrix and nanofiber reinforcement techniques. The fiber surface treatment and fiber dispersion are important factors in improving the mechanical properties of the natural fiber composites.

The use of natural fibres as reinforcements in composites has grown in importance in recent years. Natural Fibre Composites summarises the wealth of significant recent research in this area. Chapters in part one introduce and explore the structure, properties, processing, and applications of natural fibre reinforcements, including those made from wood and cellulosic fibres. Part two describes and illustrates the processing of natural fibre composites.

Critical factors on manufacturing processes of natural fibre composites

Properties of natural fibre composites for structural engineering applications

Natural fibers or natural fibres see spelling differences are fibers that are produced by plants , animals , and geological processes. The earliest evidence of humans using fibers is the discovery of wool and dyed flax fibers found in a prehistoric cave in the Republic of Georgia that date back to 36, BP. Compared to composites reinforced with glass fibers , composites with natural fibers have advantages such as lower density, better thermal insulation, and reduced skin irritation. Further, unlike glass fibers, natural fibers can be broken down by bacteria once they are no longer in use. Natural fibers are good sweat absorbents and can be found in a variety of textures. Cotton fibers made from the cotton plant, for example, produce fabrics that are light in weight, soft in texture, and which can be made in various sizes and colors.

 Какого чер… В распечатке был список последних тридцати шести файлов, введенных в ТРАНСТЕКСТ. За названием каждого файла следовали четыре цифры - код команды добро, данной программой Сквозь строй. Последний файл в списке таким кодом не сопровождался, вместо этого следовала запись: ФИЛЬТР ОТКЛЮЧЕН ВРУЧНУЮ.
