“…A fibre-reinforced composite depends as well on the contribution of some additional characteristics such as: matrix properties, fibre-matrix ratio, filler material, coupling agents and processing techniques [13]. As a consequence of imperfections in the manufacturing process, multi-layered fibre-reinforced composites are prone to early failure because of low adhesion between laminas that is, delamination [14].…”

There is significant work published in recent years about natural fibres polymeric composites. Most of the studies are about the characterization of natural fibres and their comparison with conventional composites regarding mechanical behaviour and application performance. There are dozens of types of natural fibres with different properties influencing their use, or not, in specific industrial applications. The natural origin of these materials causes, in general, a wide range of variations in properties depending mainly on the harvesting location and conditions, making it difficult to select the appropriate fibre for a specific application. In this paper, a comprehensive review about the properties of natural fibres used as composite materials reinforcement is presented, aiming to map where each type of fibre is positioned in several properties. Recent published work on emergent types of fibres is also reviewed. A bibliometric study regarding applications of natural fibres composites is presented. A prospective analysis about the future trends of natural fibres applications and the required developments to broaden their applications is also presented and discussed.

The paper presents the analysis of metalfluoroplastic materials. Russian metal-fluoroplastic materials are not meeting the requirements of regulatory and technical documentation which was adopted by Russian aircraft industry. The review of patents in the area of the methods for obtaining metal-fluoroplastic materials (MFM) was given. Perspectives of development were revealed. These perspectives of development can significantly increase the operational characteristics of metal-fluoroplastic materials. Their use allows increasing the thickness of the work polymer layer tenfold in comparison with traditional materials, and increasing work service and reliability of dry friction components. It is established that the preliminary mechanical treatment of bearing surface of the metal-fluoroplastic material allows ensuring the production of products with high accuracy and working without lubrication for a long time.

“…Defects can appear in the form of fiber ruptures, violations of fiber-matrix bonding, delamination and other types of destruction. The control of the strength of composites is not developed [1][2][3][4]. The delamination is a widespread destruction type of layered composite materials.…”

Layered composite materials are an alternative to traditional materials for the manufacture of aviation components, details and structural elements. The delamination is a widespread destruction type of layered composite materials. The paper considered the characteristically destruction of defect growth by the example of a two-dimensional defect model of elliptic delamination type. The main stages of equilibrium parameters of Griffith's cracks are considered with account of the solution of the problem of post critical deformations. The only delamination of the elliptic form exists in the plate. The energy release rate is estimated. Generalized forces which advance delamination are determined. Generalized forces are found by numerical differentiation of the potential energy with respect to the size of the delamination with infinitesimal increments.
