Description

A kind of light wood block board

Technical field

The utility model relates to a kind of light wood block board.

Background technology

At present, the made panel stiffness of common light wood fractures inadequately easily, and the high stiff case of composite industry generally adopts glass fibre and sandwich, Heavy Weight and use amount of resin are big, density is generally greater than 1, for the demanding place of some specific stiffness, such as aviation, navigation, wind electricity blade etc., these materials just can't meet the demands.And present most of sheet material processing technology complexity for will be processed into bending or the product of radian is arranged the time, forming effect is not good.

The utility model content

Goal of the invention: in order to solve the deficiencies in the prior art, provide a kind of simple in structure, utilized the high principle of compression strength of timber vertical texture, be fit to vacuum diversion and instillation process simultaneously, and be easy to a kind of light wood block board of bending forming, after shaping, in light weight, specific stiffness good.

Technical scheme: in order to realize above purpose, a kind of light wood block board described in the utility model comprises 5 layers, sandwich layer, hole sealing coating, single face bonding layer, single face fibrage up and down; Sandwich layer is a lightweight rip cutting plank, does not have fibrolaminar one side and has a group of grid deep trouth; Hole sealing coating invests the sandwich layer upper and lower surface, is made up of hole sealing agent; Fibrage is an outermost layer, comprises layer of glass at least; Bonding layer is between hole sealing coating and fibrage.

Preferably, described bonding layer is the PE PUR.

Preferably, the used material of lightweight rip cutting plank of described sandwich layer is the Balsa cork wood.The Balsa cork wood is the timber at the end of density in the present known species, 150 kilograms/cubic metre of the dried state averag densities of gas, and easily processing, and it has high withstand voltage properties perpendicular to radial longitudinal section.

Bend to radian of all sizes for the utility model is easy to, the described deep trouth degree of depth is at least 80% of core layer thickness, and width range is 0.5mm-1.2mm.

For making the utility model be more suitable for vacuum diversion and instillation process, described sandwich layer upper and lower surface has a group network shape guiding gutter, and described guiding gutter spacing range is 25mm-50mm, and the width range of groove is 2mm-3mm.

Beneficial effect: compared with prior art, a kind of light wood block board sandwich layer described in the utility model is a lightweight rip cutting plank, this kind lightweight plank is to be main material with low-density timber, such timber is fast-growing woods substantially, growth fast (5 years), and very major diameter just can be used, except that sawing, there are not other wastes during use, utilization rate and height, so need only planned the plantation during large-scale production can be very not big to the influence of environment.The plank of rip cutting can make full use of the high bearing capacity that natural wood texture vertically has, and improves the intensity of sheet material.

Simultaneously have a group network shape deep trouth at sandwich layer, easier to be manual crooked or fracture when using to be fit to preformed outline drawing through the sheet material of fluting.The degree of depth of groove, width and spacing can determine as required that the slot cross-section shape can be different shapes such as rectangle, V-arrangement.

Owing to thoroughly exposed the fiber hole after the natural timber rip cutting, in use,, coated hole sealing agent on the surface of plate for preventing to inject more resin, be used for stoping resin to enter timber in a large number and the weight that causes increases.

Fibrage comprises layer of glass at least, can not only play the effect of strengthening connection, can also improve the tensile strength of sheet material integral body.

The two-sided guiding gutter that has a group of grid of sheet material, latticed groove can make resin be easy to flow, be more suitable for vacuum diversion and instillation process, for reaching flow effect preferably, the spacing range of guiding gutter is 25mm-50mm, in order not increase too much weight after the priming by vacuum, guiding gutter can not be too big simultaneously, and the width range of groove is 2mm-3mm.

In a word, the utility model is simple in structure, be easy to be shaped, and is applied widely, in light weight after the machine-shaping, specific stiffness good.
