Obviously, the described embodiments only constitute some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort fall within the protection scope of the present application.

[0040] In order to enhance the anti-ultraviolet performance of the fiber reinforced resin-based composite structure in the outdoor environment, thereby prolonging the service life thereof under the condition of ultraviolet light, two methods are mainly adopted in the current technical field to improve the anti-ultraviolet ability. Firstly, the resin matrix of the composite is modified to introduce anti-ultraviolet components or adjust the chemical structure of the resin, so as to enhance the intrinsic anti-ultraviolet properties of the composite. The simple resin modification has limited improvement on the anti-ultraviolet ability of the composite, and has certain limitations. Secondly, an oil paint or coating with anti-ultraviolet function is sprayed on the surface of the composite to form a protective barrier, thereby effectively improving the anti-ultraviolet performance of the composite and prolonging the service life thereof. The surface spraying of the oil paint or coating can well improve the anti-ultraviolet ability of the composite, but the process is complex, additional spraying equipment is required, the environmental pollution is relatively large, special qualifications are required, and the cost is also high.

[0041] The following will be described in combination with Figures 1-3 The embodiments of the utility model are further described.

[0042] In order to solve the above technical problems, the utility model provides a kind of composite structure of anti ultraviolet and its production device, wherein, the gap in the fabric layer inside in the composite structure of anti ultraviolet is filled by connecting portion, and the overall structural strength of composite structure is enhanced, first fixed part and second fixed part are respectively arranged in the first surface and second surface of fabric layer, and are fixedly connected with connecting portion, further stabilize the structure of composite structure, prevent the relative sliding or drop-off between each layer.The first anti ultraviolet layer and the second anti ultraviolet layer are collectively wrapped substrate layer, and form double protective barrier to ultraviolet, effectively block ultraviolet to penetrate composite structure, improve the anti ultraviolet performance of composite structure outdoor application, prolong the service life of composite structure in the environment of ultraviolet light.

[0043] An exemplary embodiment of the present disclosure provides a kind of composite structure of anti ultraviolet, such as Figure 1 And Figure 2As shown, the anti-ultraviolet composite structure includes a base layer 1 and an anti-ultraviolet part. The anti-ultraviolet composite structure can be used for outdoor products, clothing or car interior decoration, such as sunshades, seat covers, etc., to effectively prevent people from being harmed by ultraviolet rays. The base layer 1 includes a fabric layer 101 and an adhesive layer. It can be understood that the fabric layer 101 includes glass fibers, carbon fibers, etc., and the adhesive layer includes resins, etc. The adhesive layer includes a connecting portion, a first fixing portion 102 and a second fixing portion 103. The connecting portion fills the gap inside the fabric layer 101. The first fixing portion 102 is arranged on the first surface of the fabric layer 101 and is fixedly connected with the connecting portion exposed on the first surface. The second fixing portion 103 is arranged on the second surface of the fabric layer 101 and is fixedly connected with the connecting portion exposed on the second surface. The second surface is opposite to the first surface. Generally, the first fixing portion 102 and the second fixing portion 103 are mainly formed of resins. In addition, in other embodiments, a third fixing portion 104 and a fourth fixing portion 105 can also be arranged. The third fixing portion 104 is used to be connected with the first bending portion 202 (described below), and the fourth fixing portion 105 is connected with the second bending portion 302 (described below).

[0044] The anti-ultraviolet part includes a first anti-ultraviolet layer 2 and a second anti-ultraviolet layer 3. The first anti-ultraviolet layer 2 is fixedly connected with the first fixing portion 102, and the second anti-ultraviolet layer 3 is fixedly connected with the second fixing portion 103. The first anti-ultraviolet layer 2 and the second anti-ultraviolet layer 3 jointly wrap the base layer 1. In this way, the first anti-ultraviolet layer 2 and the second anti-ultraviolet layer 3 provide protection from the inside and outside of the fabric layer 101, respectively, effectively blocking ultraviolet radiation from different directions, ensuring that the base layer 1 and other structures or materials inside it are not damaged by ultraviolet rays, improving the anti-ultraviolet performance of the composite structure for outdoor applications, prolonging the service life of the composite structure in an ultraviolet environment. At the same time, by fixedly connecting the anti-ultraviolet layer with the fixing portion, not only the bonding force between the anti-ultraviolet layer and the fabric layer 101 is enhanced, but also the stability and durability of the entire structure are improved, which helps to prevent the structure from loosening or being damaged due to external forces during use.

[0045] In some embodiments of the present application, reference is made to Figure 1 and Figure 2The part structure of the first fixing part 102 fills the internal gap of the first ultraviolet resistant layer 2, and the part structure of the second fixing part 103 fills the internal gap of the second ultraviolet resistant layer 3. The plurality of first fixing parts 102 and the plurality of second fixing parts 103 are arranged on the two side surfaces of the connecting part in an array respectively, and the interval between at least some of the plurality of first fixing parts 102 can be unequal, and the interval between at least some of the plurality of second fixing parts 103 can be unequal. By filling the first fixing part 102 into the internal gap of the first ultraviolet resistant layer 2 and filling the second fixing part 103 into the internal gap of the second ultraviolet resistant layer 3, the first fixing part 102 and the second fixing part 103 enhance the connection between the ultraviolet resistant layer and the fabric layer 101, thereby improving the stability of the overall structure and helping to prevent performance degradation or failure due to structural loosening or deformation. At the same time, filling the internal gap can reduce the possibility of ultraviolet penetration, further block or absorb ultraviolet rays, further enhance the protection ability of the ultraviolet resistant layer against ultraviolet rays, and thereby prolong the service life of the composite structure.

[0046] In some embodiments of the present application, referring to Figure 1 and Figure 2 The first ultraviolet resistant layer 2 comprises a first laying layer 201 and a first bending part 202 formed by bending the first side edge of the first laying layer 201 towards the fabric layer 101. The first laying layer 201 is fixed on the first surface of the fabric layer 101 by the first fixing part 102, and the first bending part 202 is laid on the third surface of the fabric layer 101, and the first surface and the third surface are arranged adjacent to each other. The included angle between the first laying layer 201 and the first bending part 202 is between 0°-180°. Exemplarily, the first bending part 202 is bent downward, so that the lower end of the first bending part 202 is in contact with the second ultraviolet resistant layer 3. The arrangement of the first bending part 202 increases the contact area between the ultraviolet resistant layer and the fabric layer 101, thereby enhancing the connection stability therebetween, helping to prevent the first ultraviolet resistant layer 2 from falling off or displacing due to external force during use, and the fabric layer 101 can be protected all around by the first bending part 202. By adjusting the shape and size of the first bending part 202, the first ultraviolet resistant layer 2 can better adapt to the shape and size of the fabric layer 101, improve the fit between the first ultraviolet resistant layer 2 and the fabric layer 101, and ensure comprehensive protection.

[0047] In some embodiments of the present application, referring to Figure 1 and Figure 2The second anti-ultraviolet layer 3 comprises a second laying layer 301 and a second bending part 302 formed by bending the first side of the second laying layer 301 towards the fabric layer 101. The second laying layer 301 is fixed on the second surface of the fabric layer 101 by the second fixing part 103, and the second bending part 302 is laid on the fourth surface of the fabric layer 101. The second surface and the fourth surface are arranged adjacently, and the third surface and the fourth surface are arranged oppositely. The angle between the second laying layer 301 and the second bending part 302 is between 0° and 180°. The second bending part 302 is bent upwards, so that the upper end of the second bending part 302 is in contact with the first anti-ultraviolet layer 2. The second bending part 302 increases the contact area between the second anti-ultraviolet layer 3 and the fabric layer 101, thereby enhancing the connection stability therebetween, preventing the anti-ultraviolet layer from falling off or moving due to external force during use, and protecting the fabric layer 101 around by the second bending part 302. By adjusting the shape and size of the second bending part 302, the second anti-ultraviolet layer 3 can better adapt to the shape and size of the fabric layer 101, thereby improving the fit between the second anti-ultraviolet layer 3 and the fabric layer 101 and ensuring comprehensive protection.

In this embodiment, the thickness of the first anti-ultraviolet layer 2 is 0.3mm, and the thickness of the second anti-ultraviolet layer 3 is 0.3mm. It should be noted that in other embodiments, the thickness of the first anti-ultraviolet layer 2 and the second anti-ultraviolet layer 3 can be the same or different. In this way, if the thickness of the first anti-ultraviolet layer 2 and the second anti-ultraviolet layer 3 can be the same, the process steps can be simplified in the production process, the production efficiency is improved, and the cost and production time are reduced. The thickness of the first anti-ultraviolet layer 2 and the second anti-ultraviolet layer 3 can be adjusted according to different application scenarios, which provides great design flexibility and adaptability, and can reduce the cost as much as possible while maintaining certain anti-ultraviolet performance.
