Description
Technical field
The present invention relates to fibre board technical field, particularly relate to a kind of water-fast carbon fiber wood composite fibre board and preparation thereof
Method.
Background technology
Along with the high speed development of material science, functional material is increasingly paid close attention to by scholars.Wherein, tool
Have high-performance, the composite wooden material of high added value has been increasingly becoming the study hotspot in this field.For meeting people to wooden
Many-sided performance requirement of material, Carbon Fiber-wood Composites material arises at the historic moment.The distinguishing feature of composite is its microcosmic
The designability of structure, the microstructure of material will determine its macro property.But due to sheet material in the course of processing because of carbon fiber
Light weight, smooth surface and being difficult to is mixed homogeneously with wood fibre and glue and electric conduction of carbon fiber has directivity.Thus easily cause
The problems such as sheet material local electrical resistance is high, and between zones of different, conductive effect difference is big, overall mechanics unstable properties.How to pass through science
The microstructure of sheet material is organically combined by means with macro property, thus improves the manufacturing process of sheet material, improves raw material
The homogenization degree of mixing becomes problem demanding prompt solution." segmentation of Carbon Fiber-wood Composites material SEM image and performance microcosmic table
Levy research " first pass through sheet material heat pressing process and complete the preparation of carbon fiber composite wood board, and the broad perspectives to model sheet material
Can test, including electric conductivity (surface resistivity), mechanical property (density, internal bond strength, MOR, springform
Amount and expansion rate of water absorption), capability of electromagnetic shielding, test data are analyzed, hold chopped carbon under the conditions of Different Preparation
Fiber composite wooden material characteristic variations rule, studies the composite microcosmic homogenization degree effect characteristics to macro property；
Model electron micrograph image is processed, from image by the image processing techniques then in conjunction with varimax with mathematical morphology
In the most complete acquisition carbon fiber image, using it as carbon fiber important evidence of uniformity coefficient in composite board；Finally
Carrying out characterizing the feature extraction of carbon fiber homogenization to the carbon fiber image extracted, selected characteristic quantity is area
Ratio, mean breadth and length-width ratio etc., it is intended that the microstructure characteristic of sheet material is combined with macro physical performance, and makees with this
For analyzing model actual application value and the important evidence improving manufacturing process.
By the research of this article, when the addition of carbon fiber is the 20% of wood fiber quality, the internal bond strength of composite
Reaching 5447MPa for 0.88MPa, MOR 36.8MPa, elastic modelling quantity, indices is better than common medium density fibre board (MDF), with
The addition carbon fiber continues to increase, and properties declines.When the addition of carbon fiber is the 20% of wood fiber quality, do not have
Reach 30dBm, not there is effective electromagnet shield effect.Want to have more preferable mechanical property and electromagnetism so that fibre board simultaneously
Shield effectiveness, needs to be modified material.And along with growth in the living standard, the anti-flammability of fibre board, resistance to water, strong
The performances such as degree, anti-radiation, heat insulation property, buckle resistance are also required to improve.
Summary of the invention
The object of the invention is contemplated to make up the defect of prior art, it is provided that a kind of water-fast carbon fiber wood composite fibre board
And preparation method thereof.
