The composite materials obtained by combining wood residues and other materials can meet the need of timber resource shortage and environmental protection, which have an extremely wide application range and represent these materials development direction due to its cost-effective, recyclable, environment-friendly properties.
Materials and Methods Test materials In this test, the wood residues of larch and birch trees were took as the substrate material, taking bamboo and phenolic resin as reinforced materials.
Conclusions According to the main production process parameters of wood composite materials, the uniform design is established to measure physical property indexes of materials with DPS.

The test results shows all the three materials were proved satisfied with bearing capacity increasing request.
The mature reinforcement methods used today are structure member strengthenting with R.C , structure member strengthenting with R.C ,structure member strengthening with externally bonded  reinforced materials,compression member confined by reinforcing wire,structure member  strengthening with externally applied prestressing,etc.[4,5,6].Three reinforcement materials with steel plate, epoxies resin sheet, and glass fiber sheet adhering to failed RC beams were compared by experiments in this paper.
Reinforcement Materials and Scheme The type of reinforcement plate is Q235, 3mm thickness, the bottom area of the reinforcement beam increases 3.0cm2; the thickness of epoxies resin sheet is 5mm, 4 cloth 5 glue boards; the width of glass fiber sheet is 50cm.
Adhesive glue used is epoxy structural adhesive .The reinforcement scheme of various materials is shown in Tab. 1.
