Description

Composite structure and clamping seat using the composite structure

This creation is about a composite structure and a holding seat using the composite structure, especially a fiber layer with interlaced long fibers bonded on the upper and lower ends of a plurality of random fiber cloths, so that when connecting an object, Effectively increase the strength of the connection between the holder and the object.

For large-scale industrial plants, due to the large area required for heat dissipation, it is often necessary to use large cooling towers for heat exchange, and then use large fans to dissipate heat. The blades of this type of cooling fan are mostly arranged in a circular array on the peripheries of two corresponding upper and lower metal turntables, and after passing through the two metal turntables with a plurality of screws, one ends of the plurality of blades are respectively fixed on Among the multiple sets of metal clamping seats between the two turntables. Among them, due to the large volume and heavy weight of the metal holder, when the fan is actually assembled, there are not only safety concerns but also a waste of manpower.

In order to make the clamping seat have sufficient strength and reduce the weight of the product to save manpower, it is considered to replace it with a fiber-shaped clamping seat. However, the current fiber composite materials mainly use heating and pressure methods to mold multiple overlapping resin-containing carbon fiber cloths. When applied to the clamping seat, since the outer shape of the clamping seat has a lot of bends, and even multiple grooves are formed, it is necessary to use a multi-layer random fiber cloth laid with short fibers and fixed and molded with resin. The random fiber cloth can be bent arbitrarily and can be smoothly pressed and molded.

However, when a complex shape of the clamping seat is formed with multiple layers of random fiber cloth, since the random fiber cloth is mainly composed of multiple short fibers, the strength that the short fiber itself can increase is limited. As a result, when a large fan rotates At this time, the clamping seat can not effectively fix one end of the blade, resulting in uneven rotation of the blade, and even causing one end of the blade to separate from the clamping seat, which may cause danger; in view of this, in order to provide a method that is different from the conventional one. The structure of the technology and the improvement of the above-mentioned shortcomings, the creators' accumulated years of experience and continuous research and development and improvement, have resulted in this creation.

One purpose of this creation is to provide a composite structure and a clamping seat using the composite structure, so as to solve the insufficient strength caused by the combination of random fiber cloth and hardened resin when the fiber clamping seat replaces the conventional metal clamping seat. The problem that one end of the large fan blade cannot be firmly and effectively connected to the fiber holder, but the upper and lower ends of the first messy cloth can be bonded respectively with the fiber layer and the upper fiber layer with interlaced long fibers. The structure of the lower fiber layer strengthens the overall mechanical strength, while reducing weight and saving manpower, it can still form a strong connection between one end of the blade and the fiber holder to ensure safe use.

In order to achieve the purpose of the above creation, the composite structure set up in this creation includes an upper fiber layer, a middle fiber layer and a lower fiber layer. The upper fiber layer includes a plurality of first filaments on the same plane; the middle fiber layer is bonded to the upper fiber layer, and the middle fiber layer includes a plurality of first random fiber cloths that are sequentially overlapped and bonded from top to bottom. A chaotic fiber cloth includes a plurality of interlaced first staple fibers on the same plane; the lower fiber layer is bonded to the middle fiber layer upward, and the lower fiber layer includes a plurality of second long fibers on the same plane.

In implementation, a plurality of first long fibers cross each other; and a plurality of second long fibers cross each other, or a plurality of second long fibers are parallel to each other.

In implementation, the plural first filaments are parallel to each other; and the plural second filaments are mutually parallel. cross.

In implementation, the plurality of first long fibers are parallel to each other, the plurality of second long fibers are parallel to each other, and the extension directions of the plurality of first long fibers and the plurality of second long fibers are the same.

When implemented, this creation further includes a covering layer, the covering layer is bonded to the upper fiber layer, and the covering layer includes a second random fiber cloth, and the second random fiber cloth includes a plurality of interlaced first fibers on the same plane. Two staple fibers.

The clamping seat using the above-mentioned composite structure provided in this creation includes a seat body, the top surface of the seat body has at least one groove, and the lower half of the seat body has two spaced first legs and two tools Spaced second leg, two first legs parallel to two second legs, two first legs and two second legs are corresponding up and down with two first perforations and two second perforations respectively There is a clamping part between the two first supporting legs and the two second supporting legs.
