Optimization of Process Parameters in Oriented Strand Board Manufacturing by Taguchi Method

Optimization of process parameters in oriented strand board (OSB) manufacturing is a vital issue for improving product quality. In this study, the Taguchi method (TM) was applied to determine the effects of production factors such as adhesive ratio, press pressure, and pressing time on the thermal conductivity of OSB. Obtained results showed that adhesive ratio is the main factor affecting ther...

Log Quality and the Strength and Stiffness of Structural Timber

A sample of 78 Pinus radiata D. Don logs was measured and sawn to maximise yields of 100 x 50-mm and 200 x 50-mm timber. The average bending strength and stiffness of the timber were found to depend on the basic density of the log but the lower fifth-percentile strength was more dependent on branch index. For the 28-year-old stand sampled, logs with a low branch index yielded 100 x 50-mm timber...

Numerical Modeling and Experiments on the Role of Strand-to-Strand Interface Quality on the Properties of Oriented Strand Board

This paper discusses numerical modeling and experimental results on stress transfer in wood composites. The numerical model treats adhesive bonds using the concept of an imperfect interface. The displacement discontinuity at an imperfect interface is proportional to the tractions at the interface. A stiff interface will result in little discontinuity and maximum translation of wood component me...

ASIC - Based Acoustic Echo - Canceller Board ' for

This paper deals with the design and realization of an echo-canceller board for a VME bus. The work has been carried out by integrating the abilities and the competences of some academic and industriai research groups within the framework of Subproject 3.1 of the ltalian National Research Council «TelecommuniCation Project». The board implements an efficient algorithm for the cancellation of ac...
