Detailed description of the invention
Contrast accompanying drawing 1, a kind of porous FRP bio-matrix plastic mixture circular beam or post, its structure is, the thick bamboo tube bamboo chip group 3 of cross-sectional internal to be tied up by ropy 5 form by being no less than 3 hollow primary thick bamboo tubes and being no less than 3 primary arcuation bamboo chips, and all thick bamboo tube diameter are equal, all primary arcuation bamboo chip equal and opposite in directions, thick bamboo tube bamboo chip group 3 overlaps with the center of circle of FRP cylinder 1, is the compound by living beings inserts 2 and molding powder particle 4 between thick bamboo tube bamboo chip group 3 and FRP cylinder 1.Described thick bamboo tube bamboo chip group 3 hollowly alleviates except deadweight except being formed, and is also important stressed ingredient.
Described living beings inserts 2 comprises leaf, stalk, the stem of straw, straw, cornstalk, sorghum stalk, beans stalk, capsicum stalk, Rape Straw, flax stalk, reed stalk, cotton stalk or crops, also comprises discarded timber and chip wood materials thereof; Molding powder particle 4 is by the plastics matter Bottle & Can crushed material in industry or household garbage.
The tension shear strength of described FRP cylinder 1 should be enough, and concrete value is relevant with the stress that the extraneous load that it is shared produces, and will be determined by practical structures designing and calculating, thickness is not less than 10mm.
Described thick bamboo tube bamboo chip group 3 is the former thick bamboo tube of 3-6 life, and this former thick bamboo tube is straight, and diameter is equal, and bamboo chip is have the primary bamboo chip of the arcuation of width.
Described bio-matrix molding powder particle is formed by adhesive (phenol glue or larch tannin resin glue or not containing the ecological glue of formaldehyde) Homogeneous phase mixing by biological material and molding powder particle.
Described living beings inserts 2 is leaf, stalk, the stem of crops, or discarded bamboo wood, timber and chip wood materials thereof, can relate to all biological materials.
The particle that described molding powder particle 4 is pulverized by plastics Bottle & Can that is industrial or daily life, its particle specification: length 20mm-40mm, width 2mm-6mm, thickness 0.2mm-2mm; Can not there be dust and greasy dirt in molding powder particle surface.
Its preparation method, comprises the following steps:
The first step, selects the FRP cylinder meeting Structural Design Requirement;
