“…In general, composite materials exhibit special features in which the strength-to-weight ratio is high. One other benefit of composite material is that it offers structural versatility since it is possible to form composites into complex shapes [88]. Composite materials obtain the majority of their advantageous properties through a tight bond between a strong rigid reinforcement-commonly fibres (filaments) or reinforcements with other geometric forms, such as particles, platelets-and a weaker, less rigid matrix [89].…”

Over recent years, enthusiasm towards the manufacturing of biopolymers has attracted considerable attention due to the rising concern about depleting resources and worsening pollution. Among the biopolymers available in the world, polylactic acid (PLA) is one of the highest biopolymers produced globally and thus, making it suitable for product commercialisation. Therefore, the effectiveness of natural fibre reinforced PLA composite as an alternative material to substitute the non-renewable petroleum-based materials has been examined by researchers. The type of fibre used in fibre/matrix adhesion is very important because it influences the biocomposites’ mechanical properties. Besides that, an outline of the present circumstance of natural fibre-reinforced PLA 3D printing, as well as its functions in 4D printing for applications of stimuli-responsive polymers were also discussed. This research paper aims to present the development and conducted studies on PLA-based natural fibre bio-composites over the last decade. This work reviews recent PLA-derived bio-composite research related to PLA synthesis and biodegradation, its properties, processes, challenges and prospects.

Purpose. To analyze composite materials and prospects of their use as fastening materials for mining of coal mines.Perform a comparative analysis of the physical and mechanical properties of the innovative material carbon fiber and metallic materials, as well as compare their features. To determine the possibility of using carbon fiber as a fastening material for mining of coal mines. Research methodology. The generalization of physical and mechanical properties of carbon fiber on the basis of its analysis is performed. The features of mechanical properties of carbon fiber, steel and aluminum are compared, which showed that this composite material has the best physical and mechanical properties and it is expedient to use it in the fastening elements of mine workings. Research results. The areas of use of composite materials in industry are analyzed and generalized, and it is concluded that it is better to use carbon fiber as a fastening material for coal mine workings. A comparative analysis of the physical and mechanical properties of carbon fiber and steel is performed, which shows that this composite material has identical (and sometimes even better) properties as metallic materials. The advantages and disadvantages of carbon fiber as a fastening material for mining of coal mines are estimated. It is specified that the restraining factor, today, is the cost of carbon fiber, and later their price will decrease and demand will increase. It is concluded that when using this composite material in the fasteners of mine workings, it is possible to increase the pace of their implementation, reduce the complexity of the work performed and improve working conditions while facilitating the design. Scientific novelty. It is established that carbon fiber as a composite material can be used in the fastening elements of the preparatory workings of coal mines. Practical value. According to the results of the analysis, it is established that carbon plastics can be used in the fastening elements of mine workings, which will promote the development of underground coal mining.

“…Usually these two different materials are known as the fiber and the matrix and the resultant composite is known as a fiber composite matrix. Fiber provides strength and stiffness while the matrix shelters it from environmental damage [ 18 , 19 , 20 , 21 , 22 ]. With technology advancement, high performance devices are emerging rapidly and the heat dissipation problem directly affects the lifetime and performance of these devices.…”

With the increasing integration and miniaturization of electronic devices, heat dissipation has become a major challenge. The traditional printed polymer circuit board can no longer meet the heat dissipation demands of microelectronic equipment. If the heat cannot be removed quickly and effectively, the efficiency of the devices will be decreased and their lifetime will be shortened. In addition, the development of the aerospace, automobiles, light emitting diode (LED{ TA \1 “LED; lightemitting diode” \s “LED” \c 1 }) and energy harvesting and conversion has gradually increased the demand for low-density and high thermal conductive materials. In recent years, carbon fiber (CF{ TA \1 “CF; carbon fiber” \c 1 }) has been widely used for the preparation of polymer composites due to its good mechanical property and ultra-high thermal conductivity. CF materials easily form thermal conduction paths through polymer composites to improve the thermal conductivity. This paper describes the research progress, thermal conductivity mechanisms, preparation methods, factors influencing thermal conductivity and provides relevant suggestions for the development of CF composites for thermal management.
