Description
Technical field
The invention belongs to quick growth poplar wood technical field of modification, is related to quick growth poplar wood modification, more particularly to outside a kind of carbon fiber
Steel plated is modified the construction technology of quick growth poplar wood.
Background technology
Timber and wood materials are not only widely used in daily life as the important resources of production in social and economic construction
In every field, be also widely used for the industrial circles such as traffic, building and space flight.With in world wide, the forest reserves are increasingly
Shortage, particularly precious timber quantity increasingly fall sharply, and substantial amounts of fast growing tree is widely cultivated in recent years.Fast growing tree has
The advantages that material time is short, yield is high, but because its growth year is shorter, such as：General artificial quick growth poplar wood become a useful person the time for 5~
6 years, thus most of fast growing tree have low density, wooden soft, physical mechanics intensity difference, moisture content high and skewness and
The defects of dry-shrinkage deformed is also easy to produce, so as to limit the use range of fast growing tree kind, generally artificial fast-growing woods uses next life
