“…The position of the fiber reinforcement within the lay-up strongly influenced the improvements. Fiber reinforcement located closer to the outer layers or at the outside can better contribute to MOE performance due to higher tensile strength within the tension zone [8,14]. In contrast, MOR is strongly dependent on the strength of the surface layer [14].…”

“…Furthermore, screw withdrawal resistance, screw-head pull-through, and lateral nail resistance of glassfiber reinforced phenol-formaldehyde bonded plywood improved significantly aside from increasing maximum load capacity [7]. conducted research on different experimental plies of poplar (Populus euramenicana), eucalyptus (Eucalyptus grandis), poplar/eucalyptus, and carbon fiber reinforced plywood for construction formwork [8]. Veneers were bonded with PF resin, whereas carbon fiber fabric was impregnated with epoxy resin and used for bonding carbon fiber to veneer.…”

“…Concluding from the studies, epoxy resin is the main source for bonding fiber reinforced wood-based composites with synthetic and natural fibers. Some attempts had been made to use PF, UF, and MUF [6][7][8][9]13,14]. For broader industrial production applications, the use of different adhesives is desirable due to the high production costs of epoxy resin systems.…”

In order to improve the acceptance of broader industrial application of flax fiber reinforced beech (Fagus sylvatica L.) plywood, five different industrial applicated adhesive systems were tested. Epoxy resin, urea-formaldehyde, melamine-urea formaldehyde, isocyanate MDI prepolymer, and polyurethane displayed a divergent picture in improving the mechanical properties—modulus of elasticity, modulus of rupture, tensile strength, shear strength and screw withdrawal resistance—of flax fiber-reinforced plywood. Epoxy resin is well suited for flax fiber reinforcement, whereas urea-formaldehyde, melamine urea-formaldehyde, and isocyanate prepolymer improved modulus of elasticity, modulus of rupture, shear strength, and screw withdrawal resistance, but lowered tensile strength. Polyurethane lowered the mechanical properties of flax fiber reinforced plywood. Flax fiber reinforced epoxy resin bonded plywood exceeded glass fiber reinforced plywood in terms of shear strength, modulus of elasticity, and modulus of rupture.

“…31 In addition, carbon fiber has the characteristics of high strength and high modulus along the fiber axis, and is widely used in fiber-reinforced resin composite materials. 38,39 By coating the surface of carbon fiber with metal, plating SiC, and deposition of graphite carbon particles, the conductivity of carbon fiber can be further improved, and better EMS materials can be obtained. Carbon fiber EMS composite materials include the filling type and composite type.…”

With the widespread adoption of electronic technology, electromagnetic (EM) interference has become increasingly severe, adversely affecting the normal operation of electronic systems and posing significant threats to human health. EM shielding materials can effectively suppress various EM waves and EM interference generated through space by improving the EM compatibility of electronic systems and electronic devices. Recently, fiber-structure materials have been widely used for EM shielding due to their softness, thinness, and superior shielding efficiency. Therefore, this paper focused on fiber-based EM shielding materials, discussed the basic principles of EM shielding, the types of EM shielding fibers, the efficiency factors of EM shielding fabrics, and presented prospects for the future development of such materials.

The present study describes the manufacturing of flat sheets of eucalyptus-basalt based hybrid reinforced cement composites (EB-HRCC). The potential of basalt fibrous waste (BFW) as a reinforcement agent in cement matrices and its effects on mechanical and interfacial properties were evaluated in detail. Significantly enhanced bending (flexural) strength and ductility were observed for all developed composite samples. BFW and eucalyptus pulp (EP) were utilized as reinforcement and filling agents respectively for EB-HRCC samples. Mechanical, microstructural and physical properties of EB-HRCC samples were investigated with different formulations of BFW with EP in cement matrices. The results showed that physical properties of the composite samples were more influenced by fiber content. For standard mechanical analysis, the composite samples were placed in sealed bags for two days, thermally cured at 60 °C for five days and immersed in water in ambient conditions for one day. The obtained results showed that samples prepared under optimized conditions (4% EP and 2% BFW) had significantly higher flexural strength and bulk density with lower water absorption and apparent void volume (porosity). Moreover, the higher percentage of BFW significantly enhanced the values of modulus of rupture (MOR), modulus of elasticity (MOE), specific energy (SE) and limit of proportionality (LOP). The effects of entrapped air under the four-point bending test on the mechanical behavior of hybrid composites were also investigated in this thematic study. The composites were designed to be used as roofing tile alternatives.
