Correlation between Radial Variation and Mechanical Properties of Laminated Veneer Lumber made from 14 Poplar Cultivars
France is poplar largest producer in Europe. Most of companies have a very specialized raw material supply chain since they use almost one type of cultivar for their specific products. For example, I-214 is very suitable for light packaging, consider as exclusive raw material in all industries. Howe...
