چکیده
This study investigates the impact of adhesive spread rates and lamina assembly patterns on physical mechanical properties glue laminated lumber (glulam) manufactured from Kelempayan wood (Neolamarckia cadamba (Roxb.) Bosser). For this purpose, lab-scale 3-ply homogenous glulams were using low-MOE, average-MOE, high-MOE laminas, mixed low-high-low-MOE high-low-high-MOE lamina, with an rate 100 g/m2 applied both sides lamina. A glulam was also average-MOE 200 g/m2. The glulam, including moisture content, density, modulus rupture (MOR), elasticity (MOE), examined compared to Japanese Industrial Standards (JAS) for glulam. results found that did not have a significant effect However, had highest MOR MOE observed in followed by laminas. These meet requirements specified homogeneous structural grade standard, indicating can be feasible option production.

11 A feasibility study of glulam was carried out in French Guiana using local wood species. The aim 12 was to determine gluing parameters affording satisfactory behaviour to manufactured glulam in 13 a tropical climate. 14 Three abundant wood species, with special properties, were selected for the study and 15 Resorcinol-Phenol-Formaldehyde resin was used for bonding. Three industrial parameter...

The paper presents the computer-aided design and construction of a large glued laminated timber structure in Aosta, Italy. The structure was completely computer modelled with in-house developed software, which considers both torsion and curvature constraints of timber. Further proprietary software was used to develop, on a plane, the shape of each timber layer without torsion and curvature . Th...
متن کاملAir-coupled ultrasound inspection of glued laminated timber
A novel air-coupled ultrasound (ACU) 120 kHz normal transmission system enabled successful imaging of bonding and saw cut defects in multilayered glulam beams up to 280 mm in height with a signal-to-noise ratio (SNR) of 40 dB. The main wave propagation paths were modeled; quasi-longitudinal and quasi-transverse modes were coupled in each lamella and the sound field was found to be shifted from ...
