The need to develop and commercialize materials containing vegetal fibers has grown in order to reduce environmental impact and reach sustainability. Large amounts of lignocellulosic materials are generated around the world from several human activities. The lignocellulosic materials are composed of cellulose, hemicellulose, lignin, extractives and ashes. Recently these constituents have been used in different applications; in particular, cellulose has been the subject of numerous works on the development of composite materials reinforced with natural fibers. Many studies have led to composite materials reinforced with fibers to improve the mechanical, physical, and thermal properties. Furthermore, lignocellulosic materials have been treated to apply in innovative solutions for efficient and sustainable systems. This paper aims to review the lignocellulosic fibers characteristics, as well as to present their applications as reinforcement in composites of different polymeric matrices.

NFTCs are often presented as a more environmentally friendly product which may, in some cases, offer useful levels of specific strength and stiffness with an overall reduced carbon footprint.
Layth Mohammed, M. Natural fibers are getting attention from researchers and academician to utilize in polymer composites due to their ecofriendly nature and sustainability. The aim of this review article is to provide a comprehensive review of the foremost appropriate as well as widely used natural fiber reinforced polymer composites NFPCs and their applications. In addition, it presents summary of various surface treatments applied to natural fibers and their effect on NFPCs properties. The properties of NFPCs vary with fiber type and fiber source as well as fiber structure.

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 ]. These supports are optimised for the individual modalities, meaning that the same patient support cannot simply be moved between machines which would allow for optimum positioning. In addition, they must have sufficient strength and be light enough for safe and convenient operator removal.
Biocomposites natural fiber composites from local and renewable resources offer significant sustainability; industrial ecology, eco-efficiency, and green chemistry are guiding the development of the next generation of materials, products, and processes. Considerable growth has been seen in the use of biocomposites in the domestic sector, building materials, aerospace industry, circuit boards, and automotive applications over the past decade, but application in other sectors until now has been limited. Nevertheless, with suitable development, the potential exists for biocomposites to enter new markets and thus stimulate an increase in demand. Many types of natural fibers have been investigated with polymer matrices to produce composite materials that are competitive with synthetic fiber composites which require special attention. The agricultural wastes can be used to prepare fiber-reinforced polymer composites for commercial use and have marketing appeal. The growing global environmental and social concern, high percentage of exhaustion of petroleum resources, and new environmental regulations have forced the search for new composites, compatible with the environment. Many references to the current status of research work on the applications of biocomposites are cited in this review.

Micro-structural analysis and elastic properties of oil palm trunk fibre reinforced polyester composites. Anthony N. Oladiran K. Abubakre b. This work addressed the study of development of micro-structure as related elastic properties in oil palm trunk fibre reinforced polyester composites. The cross-sections of the specimens examined by Scanning Electron Microscopy indicated that the failure pattern of treated fibre composites was gradual, and related to the stiffness prominence.
The rapid consumption of petroleum-based products and its negative impact on the environment has lead to an increase in environmental consciousness when it comes to sustainable materials and products. Natural fibres are categorised as an environmental friendly material, which contains good properties, compared to synthetic fibres. Advantages of natural fibre composites In it simplest definition natural fibres are sourced from plants or animals, meaning they are not synthetic or manmade. Natural fibres can come from a large variety of fibre sources:. When it comes to the properties of the natural fibres, it is important to state that difference occurs when choosing one type of fibre over another. The performance of the composite depends on many factors such as structure, mechanical composition, physical properties, cell dimensions, microfibrillar angle etc. Fibre reinforced composites have received much attention based on different applications because of the good properties and the advantages found over synthetic fibres.
Сосредоточившись, Сьюзан перезагрузила Следопыта и нажала клавишу ВВОД. Терминал пискнул.
Сьюзан, - начал он, - я не был с тобой вполне откровенен. ГЛАВА 73 У Дэвида Беккера было такое ощущение, будто его лицо обдали скипидаром и подожгли. Он катался по полу и сквозь мутную пелену в глазах видел девушку, бегущую к вращающейся двери.
Как у всех молодых профессоров, университетское жалованье Дэвида было довольно скромным. Время от времени, когда надо было продлить членство в теннисном клубе или перетянуть старую фирменную ракетку, он подрабатывал переводами для правительственных учреждений в Вашингтоне и его окрестностях. В связи с одной из таких работ он и познакомился со Сьюзан.
