“…The results of the MOR and MOE show that the plywood panels tested in the parallel direction the bers were considerably larger than those of the samples tested perpendicular to the bers. This behavior was consistent with the ndings of Auriga et al 2020). Although the values of MOR and MOE in the parallel direction were higher than those of MOR and MOE in the perpendicular direction, the results did not meet the requirements of the NBR 31.000.001/2:2001 standard, which establishes values of MOR for concreteshaped plywood (FOR) of at least 45 MPa.…”

The quality of plywood panels depends on factors such as the forest species and the adhesive used in their production, and understanding the interferences of these factors in the final properties of the plywood is of fundamental importance. The study aimed to develop multilaminate plywood panels with two forest species and two types of adhesive and to evaluate the influences of these factors (forest species and adhesive) on the physical and mechanical properties of the plywood. The panels were produced with sheets of parica and pine with two types of adhesives, urea-formaldehyde and phenol-formaldehyde, with a weight of 150 g/cm². Then, each set was pressed for 10 minutes under a specific pressure of 0.98 MPa at a temperature of 150 °C. Three panels were produced for each type of blade and adhesive, totaling four treatments. The plywood was evaluated for physical properties (humidity, bulk density, and water absorption) and mechanical properties (parallel and perpendicular static flexion and resistance to mechanical shear). The results showed that the forest species had a greater influence on physical and mechanical properties, with the best results being observed for plywood produced with pine. The panels with sheets of parica and phenol-formaldehyde adhesive showed less moisture. The apparent density of the panels should be considered as it positively influenced the mechanical properties and negatively impacted water absorption. It is concluded that the plywood produced can be used for internal and external applications. However, it is indicated for structural purposes as it did not meet the requirements of the NBR 31.000.001/2:2001.

“…CF reinforcement was located at two different positions: external at the outer glue line and internal surrounding the core veneer ply. The results displayed increasing modulus of rupture (MOR) and modulus of elasticity (MOE) and the influence of fiber reinforcement location on MOR and MOE [9]. Guan et al (2020) evaluated the three point bending performance of unidirectional CF (EL 203,631 N/mm 2 ) reinforced eucalyptus (EL 11,619 N/mm 2 )/poplar (EL 6751 N/mm 2 ) epoxy resin bonded plywood (thickness 17.5 mm, 17.8 mm, 17.65 mm, 18.0 mm) by digital image correlation (DIC) and finite element analysis (FEA), concluding the usability of FEA for the prediction of material failure behavior [10].…”

“…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.

El polímero reforzado con fibra de carbono (PRFC) hoy en día se ha vuelto una alternativa de material de fortalecimiento para las estructuras en la construcción porque mejora las propiedades mecánicas del concreto y aunque es un proceso de fabricación de costo elevado, origina un gran beneficio para la estructura de concreto armado (CA). El objetivo de este trabajo ha sido revisar la investigación notable publicada en revistas indexadas de los años 2012 a 2021 (41 artículos de Scopus, 7 de EBSCO, 2 de Science Direct y 1 de Redalyc), sobre el uso del polímero reforzado con fibra de carbono en elementos estructurales, como reforzamiento interno o externo, que beneficia a la estructura en su periodo de vida, al impacto ambiental que este produce, al costo del material y al manejo del material in situ.
