“…The cross-sectional and longitudinal views of the fibers along with flatness and unevenness were observed by SEM. The Keyence VHX 6000 digital microscope model was used, in which the microscopic image is processed by computer-assisted drawing software to determine the area of the fiber section [27].…”

“…Natural fibers have low thermal conductivity, which makes them suitable for composite materials used for construction [24]. The addition of natural fibers improves the thermal, mechanical and acoustic characteristics of construction materials [25][26][27][28]. The addition of fibers increases the tensile strength and post-peak load-bearing capacity of construction materials [12].…”

The palm oil industry is the leading source of palm oil waste fibers. The disposal of palm oil waste fibers by burning or dumping causes environmental issues such as the emission of CO2 and a diminution in soil fertility. Natural fiber reuse in construction materials such as concrete, mortar and adobe bricks as reinforcement provides a possible eco-friendly solution for fiber waste management. Palm oil flower fibers (POFL) obtained from palm oil empty fruit bunches and palm oil fruit fibers (POFR) obtained from palm oil fruit are two important types of palm oil fibers. Valorization of palm oil fibers requires a detailed analysis of their physical, chemical and mechanical characteristics. In this research, tropical palm oil flower and palm oil fruit fibers from Mexico were studied. Fiber extraction, preparation and testing were performed to observe their characteristics, which include water absorption, density, length, section estimation, chemical composition, thermal conductivity, thermal analysis (ATG) and tensile strength. The length, diameter and density of natural fibers have a significant influence on the strength and quality of composite materials. The characteristics of fibers vary with their chemical composition. Mechanical testing of palm oil fibers indicates a large variation in the tensile strength of palm oil flower and fruit fibers. Both palm oil flower and palm oil fruit fibers exhibit bilinear tensile load–deflection behavior associated with the alignment of cellulose along their fiber axis. The thermal characteristics of fibers indicate low thermal stability and thermal conductivity, which are essential for their use in building materials.

Coconut (Cocous nucifera), also known as the "tree of heaven," is one of the most important marketable crops in tropical countries. Research and commercialization of the technology is needed as to provide an additional source of income and to improve the economic status of the farmers and the country. Some physical and engineering features such as size, weight, sphericity, roundness, volume, and density were researched as part of the steps toward developing processing and handling equipment for coconuts. Major diameter varied from 132.23 mm to 101.45 mm with a mean value of 117.24 mm, the seed volume varied from 713.45 cm3 to 425.88 cm3, with an average density of 1.0427 g cm-3. The roundness ranges from 0.4607 to 0.8216 with a mean value of 0.6490 and the sphericity ranges from 0.7304 to 0.9561 with a mean value of 0.8330.

“…The researchers observed that palm fiber [ 1 ] reduced the early drying shrinkage of concrete; it is found that the addition of natural fibers creates a good thermal insulation performance for cement mortar, hemp shives [ 2 ], flax straw, granular cork, and palm fiber [ 3 ]. Especially in terms of mechanical properties, the researchers reported that natural fibers (such as sisal fiber [ 4 ], coir [ 5 , 6 ], coconut [ 7 , 8 ], açaí fiber [ 9 ] and human hair fiber [ 10 ]) improve the compressive strength and flexural strength of NFRC. Using sisal fiber could enhance the impact resistance [ 11 , 12 ] of NFRC.…”

Natural fiber-reinforced concrete (NFRC) has the advantages of environmental protection, energy conservation and regeneration. However, studies conducted to improve the macro mechanical properties of concrete by pine needle fiber have achieved good results. In this paper, the deformation and compression damage of pine needle fiber-reinforced concrete (PNFRC) are analyzed by digital image correlation; a fractal dimension is used to quantify the shape of PNFRC after compression damage; and the results of scanning electron microscopy confirm the effect of fiber treatment on deformation and damage of concrete. The results showed that the horizontal strain field of PNFRC has strain concentration zones in the elastic deformation stage, indicating that the fiber enhances the deformation ability of concrete. The defined damage factor can reflect the damage of fiber-reinforced concrete (FRC). The damage curve of natural fiber concrete increases evenly and slowly compared to ordinary concrete.
