The authors investigated the typology and characteristics of recent technology innovation in particleboard and composite materials. Conducting a cluster analysis of data derived from a content analysis of the International Particleboard/Composite Materials Symposium Proceedings, they identified four major clusters of like-type technology innovations – manufacturing, high technology, materials p...

In a previous study by the authors, particleboard was manufactured using a new natural adhesive composed of tannin and sucrose. The optimal ratio between tannin and sucrose was 25/75, and the suitable resin content was 30 to 40 wt%. In this study, the effects of hot pressing temperature and hot pressing time on board properties were investigated. The optimal values for the hot pressing temperat...

the creep/recovery behavior of wood flour-polypropylene was compared with medium density fiberboard (mdf) and particleboard. for this purpose, wood flour-polypropylene composites (with and without compatibilizer)were manufactured by using a laboratory twin-screw extruder. the mdf and particleboard panels were obtained from local producers. short term flexural creep tests at 30% of ultimate bend...

This paper presents a new kind of composite produced with smalldiameter bamboo (Phyllostachys glauca McClure) and extruded tubular particleboard. The mechanical properties of the composite are significantly affected by the properties of the bamboo. First, the compression strength of the bamboo was studied. It was found that the compression strength (fc, MPa) and the maximum force of compression...

The reliability of furniture constitutes one the most important features taken into consideration when buying furniture. However, to evaluate reliability, manufacturers often rely on their own experiences and common patterns without usage specialized tools. presented work aimed develop a mathematical apparatus be used in specially created web application that would enable calculation selected j...

the moe and mor are controlled by production variables of particleboard process. now, the basic question is which of the particleboard variables is effective on bending strength property? 13 variables of internal scientific resources were measured with 100 repeats. the study steps include the following; liner regression or stepwise, genetic algorithm, and artificial neural network. the number o...

this study was conducted to evaluate the effect of feeding treated wheat straw with urea and whey on fattening lambs performance. about 4.5 kg urea and 1.5 kg salt were dissolved in 40 l water and mixed with 30 l of whey. the solution was spread over 100 kg chopped wheat straw. thirty two male lambs were randomly divided into four feeding groups to compare performance with diets based on barley...

This experiment compared the effects of sand and straw bedding in free stalls on resting time, cleanliness, hock injuries, and hoof health of dairy cows and tested whether cow preferences for a bedding material depended on the familiarity with the material. A total of 52 dairy cows were kept either on straw bedded concrete stalls or sand stalls for at least 21 wk. The lying behavior was observe...
