Multi-scale modelling on the failure process in wood composite products

加拿大是木材原材料和半成品的主要出口国。不幸的是，近年来可收获的成熟树木数量大幅下降。由于山地松甲虫的袭击，北方不列颠哥伦比亚省的大片森林遭到破坏，这种情况更加恶化。如果能在不砍伐北方森林的情况下制造和出口更多的木材成品，将有利于沿海和北方地区的林业和经济，也有利于该国的总体环境管理。一个可行的策略是，当用于建造低层住宅和商业建筑的结构构件是由小块木材在热和压力下与合成树脂粘合而成时。

Canada is a major exporter of raw and semi-finished wood products. Unfortunately the quantity of harvestable mature trees has declined considerably in recent years. This situation has been exacerbated by the destruction of large tracts of forests in northern British Columbia due to the mountain pine beetle attack. It would be beneficial to the forestry industry and economy of coastal and northern regions as well as the overall environmental stewardship of the country, if more finished wood products were manufactured and exported without resorting to cutting of Boreal forests. A viable strategy is when structural members for the construction of low-rise residential and commercial buildings are manufactured from small pieces of wood bonded with a synthetic resin under heat and pressure.
