“…The study found that making use of woven glass fiber to reinforce LVL had some positive influences and some negative influences on the mechanical properties. Wang et al (2011) introduced an investigation to reinforce LVL with ramie fiber. The study indicated that using ramie fiber to enhance LVL could improve the mechanical properties of LVL, especially the level of shear strength.…”

Three types of reinforcement materials, a carbon fiber-reinforced polymer (CFRP) sheet, a glass fiber-reinforced polymer (GFRP) mesh, and a composite of the CFRP sheet and GFRP mesh, were used to reinforce poplar laminated veneer lumber (LVL), and the multi-step hotpressing method was also applied. The mechanical properties, i.e., modulus of rupture (MOR), modulus of elasticity (MOE), and horizontal shear strength (HSS), of the reinforced LVL were investigated, as well as the effects of lay-up location of the CFRP sheet/GFRP mesh composite. The results indicated that applying the multi-step hot-pressing method and incorporating the CFRP sheet, GFRP mesh, and the CFRP sheet/GFRP mesh composite noticeably improved the MOR and MOE under horizontal and vertical loadings. Only the multi-step hot-pressing method was able to greatly improve the HSS of reinforced LVL under both loading modes. The improved effect of the three kinds of reinforcing materials on the mechanical properties was ordered as follows: CFRP sheet/GFRP mesh composite > CFRP sheet > GFRP mesh. Locating the CFRP sheet/GFRP mesh composite closer to the surface veneer layer yielded the best mechanical properties for the reinforced poplar LVL.

“…In the related research, the effects of different forming structures and percentages of adding woven glass fiber on reinforced laminated veneer lumber were explored, which showed that the glass fiber has great effects on mechanical properties of laminated veneer lumber when reinforce by using woven glass fiber [7]. Glass fiber was also applied to reinforce the laminated veneer lumber, it greatly improved the properties of laminated veneer lumber, especially the shear strength [8,9]. Meanwhile, it was found that the polypropylene material when reinforced by fiber has greater flexural strength and lower water absorption rates [10].…”

Fiber reinforced materials have been widely used in the different fields in terms of their excellent properties. In this work, glass fiber reinforced poplar scrimber was in focus, and special attention was given to its dimensional stability with respective of different layers (0, 1, 2, 3) and mass fraction (1.5 wt.%, 3.0 wt.%, 4.5 wt.%, 6.0 wt.%, 7.5 wt.%) of glass fiber mesh. The experimental results showed that the glass fiber reinforced poplar scrimber with 2 layers and 6.0 % mass fraction of glass fiber mesh has the greatest dimensional stability and energy efficiency ratio. It is proposed to be adopted in the industrial processing of glass fiber reinforced poplar scrimber to improve its application and production benefit.

The mechanical properties of poplar scrimber reinforced with glass fiber mesh were investigated. The influence of the different structures and densities were studied with respect to the modulus of rupture (MOR), modulus of elasticity (MOE), and impact toughness (IT). The glass fiber improved the mechanical properties of poplar scrimber. The MOR, MOE, and IT of the scrimber had an obvious dependence on the number of glass fiber layers. When the layers of glass fiber meshes were increased, the MOR, MOE, and IT were increased compared to the control group (scrimber without glass fiber reinforcement). The MOR, MOE, and IT of single-layer glass fiber reinforced scrimber increased a lot compared to the control group. The MOR, MOE, and IT of double-layer glass fiber reinforced scrimber (DGRS) were increased, but the amplitude of the increase was smaller than that of SGRS. Compared to the MOR, MOE, and IT of DGRS, the MOR, MOE, and IT of triple-layer glass fiber reinforced scrimber (TGRS) decreased slightly. When the density was increased, the increasing rate of the MOR, MOE, and IT of the glass fiber reinforced scrimber showed a downward trend, and the glass fiber had better strengthen effects on the scrimber at low density (0.6 g/cm 3 and 0.7 g/cm 3 ).
