Description
Technical field
The invention belongs to quick growth poplar wood technical field of modification, are related to outside quick growth poplar wood modification more particularly to a kind of carbon fiber
The construction technology of the modified quick growth poplar wood of steel plated.
Background technique
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, especially precious timber quantity increasingly fall sharply, and a large amount 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 since its growth year is shorter, such as: general artificial quick growth poplar wood become a useful person the time be 5~
6 years, thus most of fast growing tree have low density, wooden soft, physical mechanics intensity difference, moisture content high and be unevenly distributed and
