TL;DR: Lab results demonstrated that E. nitens plywood satisfies all the British Standard Institution requirements for exterior use and bonding quality in solid wood of juvenile (11 years) E. Nitens.
Abstract: SUMMARY This work evaluates the bonding quality in solid wood of juvenile (11 years) E. nitens. Edge-glued panels were manufactured and bonded with PVA (Polyvinyl acetate). The mechanical properties of the panels were determined and compared with those of mature (25 years) P. radiata panels. Shear strength values in E. nitens panels were found to be 35% higher than P. radiata panels according to British Standard EN 204-205 on non-structural adhesives for wood joining. Juvenile E. nitens wood venners were used to manufacture exterior ‐grade plywood panels. Laboratory results demonstrated that E. nitens plywood satisfies all the British Standard Institution requirements for exterior use.

TL;DR: In this paper, the Young's elastic modulus (EMO) was determined by three methods in a five-layer plywood from Eucalyptus nitens wood.
Abstract: It was determined the Young`s elastic modulus (EMO) by three methods in a five-layer plywood from Eucalyptus nitens wood. The control method had the lowest variability (22,45 %). The lower standard error respect to control method, corresponds to method 2 with a coefficient of 0,566. While, the higher variability correspond to method 3 (29,91%). However, the ANOVA indicates not significant difference between the means of each method. The average of Young`s elastic modulus obtained of 10,18 GPa in axial direction, indicates that the elastic behavior of plywood is similar to E. nitens solid wood (9,6 GPa). In addition, EMO obtained indicates that the plywood meets the requirements of brazilian standards NBR 9531 and NBR 9523 and european EN 310-1993, allowing its use in interior light construction, as concrete mold, furniture and general uses, although, according to APA standard not classified for heavy construction, marine and industrial use.
