“…Results reveal that oleoyl chloride treated composites are thermally stable than untreated composites with a maximum degradation of 359°C. [ 329 ] Cellulose nano fibers incorporated with oleic acid and further cross linked with sulfur vulcanized natural rubbers were investigated. Best mechanical properties are obtained in composites when treated with 5% oleoyl acid with a Young's modulus 27.7 MPa, which are higher than untreated counterparts.…”

Application of natural fiber-polymer composites (NFPCs) in different industrial applications provides competitive edge due to their lightweight, higher specific mechanical properties than glass fibers, sustainability, and lower cost involved in production. There are certain challenges associated with natural fibers and their reinforcement in composites such as poor bonding between the fibers and matrix due to their contradictory nature of characteristics, moisture absorption, lower thermal properties, and poor interfacial adhesion between the natural fiber and polymer matrix. The challenges involved in NFPCs need to be overcome to produce materials with relatively equivalent properties to those of conventional composites and other metallic structures. Several researchers around the globe have conducted investigations with the primary attention being paid to the modification of natural fibers and matrix by employing surface treatments and other chemical treatment methods. In order to address the need for eco-friendly and sustainable materials in different domains, a comprehensive review on natural fibers and their sources, available matrix materials, modification techniques, mechanical and thermal properties of NFPCs, is needed for better understanding of the behavior of NFPCs. This work provides the information and holistic view of natural fiber-reinforced composites based on the results obtained from modification techniques, with the view of focusing the review in terms of different chemical and physical treatment techniques, modification of fibers and matrix, and enhanced mechanical and thermal properties in the composites.

“…The oleoyl chloride treatment involves the use of oleoyl chloride which are fatty acid derivatives, which reacts with the hydroxyl group of the cellulose present in the fiber, thus improving the adhesion to the matrix material and reducing the moisture content of fiber [34,100,101].…”

“…The thermal properties of NFCs depend on the thermal conductivity of natural fibers and matrix, the thermal resistance between the interfaces of fiber and matrix [100,224]. The thermal conductivity of matrix material in a NFC with a low content of natural fibers is close to that of the matrix material [225,226].…”

A rapid growth in the research and employment of natural-fiber composites (NFCs) has been observed in the last years. This is explained by their many advantages, such as the biodegradability, eco-friendliness, a relatively low cost, and good mechanical properties. Despite these advantages, they also possess some undesirable features, such as difficulties in processing, high fiber moisture absorption, low impact strength, low durability, poor fire resistance, and poor compatibility between fibers and matrix. Much effort has been applied to minimizing these issues in order to extend the capabilities and applications of this group of materials. In an attempt to provide a better insight into NFCs, an up-to-date review of their manufacturing routes, different applications, and mechanical performance is very required. This review aims to address the above-mentioned issues challenges encountered when dealing with such materials.

что приводит к меньшему снижению предела текучести образца СВМПЭ+ +20% по массе ПП в зоне контакта и соответственно к меньшему износу.Показано, что введение частиц и/или волокон для повышения теплопроводности играет двоякую роль. С одной стороны, отвод тепла снижает температуру непосредственно в зоне контакта, в результате предел текучести снижается в меньшей степени и износ уменьшается. С другой стороны, наличие включений приводит к появлению зон концентрации напряжений в их окрестности и локализации деформаций в относительно податливой матрице. Поскольку включения меньших размеров вызывают меньшие концентрации напряжений, использование углеродных нанотрубок более эффективно, чем углеродных волокон.Благодарность.
