Untersuchungen an einer aus Faserplatten- und Furnierschtichten zusammenfesetzten Schichtholzplatte (SHP)

The development of a laminated wood board of different design is, among other, a solution to the worsening situation of wood supply in production of standard veneer boards. At the same time, the supply of wood boards with speical properties may be enlarged. This was the reason to investigate a laminated wood board, composed of veneer layers and fiber boards. Analyses and comparisons showed that some mechanical and physical properties of the composite board are similar to those of plywood (C _k) (rectangular grain) and laminated board (C _x) (parallel grain).     

Natural decay resistance of LVL made of veneers from durable and non-durable wood species

Laminated veneer lumber (LVL) was laboratory manufactured using veneers from decay and non decay resistant species in order to evaluate changes in the durability as a result of the LVL manufacturing process, and to test if the mixing of decay resistant species and non decay resistant species can improve durability. Laboratory soil block test and field test were conducted. The durability of solid wood was comparable to that of LVL made using the same species. For LVL made using veneer from durable and non-durable wood species, durability was improved when two faces and one core veneers were from decay resistant species.

Veneer sheet density measurement by the 55Fe gamma attenuation method

This paper presents a very low gamma energy radiation method for the measurement of density distributions of veneer sheet. The method is based on a narrow beam measurement geometry, where the equipment scans the specimen sheet placed between the ⁵⁵Fe radiation source emitting 5.9 keV photons and the Nal-detector. The density distribution is determined by measuring the number of photons passing through the veneer sheet. By the method the dry wood density can be determined by measuring also the moisture content of the sheet. The dry wood density can be estimated with good accuracy without moisture measurement when the moisture variation is limited to a few per cent.
