Abstract
The utility model relates to a sandwiched composite felt with double sides combined with composite woven twill, which mainly comprises non-woven fabric. The upper surface and the lower surface of the non-woven fabric are provided with the composite woven twill, and the lower side of the composite woven twill on the lower part is provided with a chopped layer; and the four layers are woven through polyester strings. Although the thickness of the product is increased, the texture of the product is soft, and all the layers can be laid within one step during operation. Based on actual experience, the problem of laying multiple layers can be solved effectively through weaving a plurality of layers of composite woven twill, non-woven fabric and chopped felts together.
Description
Technical field
The utility model relates to a kind of composite, and refering in particular to is a kind of two-sided combined twills woven roving sandwich composite felt that is used to make the wind power generating set parts.
Background technology
The existing composite products that is used to make wind power generating set, body layer use plain weave organizational composition at 0 ° with 90 ° of directions based on glass rove; When producing, need repeatedly shop layer, repave at last and shortly cut felt, occur fiber accumulations easily in the mould corner or the shop layer is not in place, fold occurs, influence surface smoothness most, and be not easy to finalize the design.On the other hand, repeatedly spread layer during production and make same operation repetitive operation, production efficiency and artificial utilization rate are low, and production cost is high.
The utility model content
The purpose of this utility model is that a kind of quality softness, surfacing, intensity height, two-sided combined twills woven roving sandwich composite felt that application performance is good are provided for the deficiency that solves above-mentioned technology.
In order to achieve the above object, the two-sided combined twills woven roving sandwich composite felt that the utility model is designed, mainly be made of the twill woven roving, it is characterized in that adding the core layer of non-woven fabric in the middle of the described twill woven roving, the downside of one deck woven roving is provided with the short layer of cutting therein; And four layer by layer structure compile by the polyester linear slit.
Wherein:
Described twill woven roving is to be made of two times weaving structures in the glass fiber yarn employing two;
Described nonwoven is made of chemical fibre chopped strand needling structure;
Described weak point is cut layer and is made of glass chopped yarn.
The resulting two-sided combined twills woven roving sandwich composite felt of the utility model, selecting the using-system structure is the weaving process under two on the plain weave, two; Upper and lower surface uses the twill woven roving, and the nonwoven in addition in the centre with the omnidirectional product surface that is uniformly distributed in of chopped strand, is compiled by the polyester linear slit and to be formed.Though this product thickness increases, quality softness, and all lay-up process one-time-reach-places in the operating process.According to practical experience, multilayer twill woven roving, nonwoven, weak point are cut the felt loop bonding so together, can effectively solve the problem of multilayer shop layer.Select the twill woven roving of particular tissues structure simultaneously, guarantee that multi-layered product is sewed up after, the quality softness.This product has good ductility and tensile force, thereby subsides property is fabulous, and the twill woven roving has been accelerated resin flows when resin pours into simultaneously, is a plurality of directions, and final multiple spot constitutes an integral body.In sum, the two-sided combined twills woven roving sandwich composite felt that the utility model obtains has that product is thick, quality is soft, smooth, hole is many, wetting-out rate is fast, cover mould and mold filling character is good, be difficult for displacement, and the characteristics of any surface finish.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model will be further described in conjunction with the accompanying drawings below by embodiment.
Embodiment 1:
As shown in Figure 1, the two-sided combined twills woven roving sandwich composite felt that present embodiment is described mainly is made of twill woven roving 2, and sandwiches have or not and spin cloth 1 in the middle of the described woven roving 2, is provided with the short layer 3 of cutting at the downside of bottom twill woven roving 2; And four layer by layer structure compile by the polyester linear slit.
Wherein:
Described twill woven roving 2 by glass fiber yarn form two on two times weaving structures constitute;
Described nonwoven 1 is made of chemical fibre chopped strand needling structure;
Described weak point is cut layer 3 and is made of glass chopped yarn.
