Description

Technical Field

[0001] This utility model relates to the field of glass fiber cloth technology, and in particular to a glass fiber cloth with a built-in high-strength tensile rib structure. Background Technology

[0002] Fiberglass roving is a plain weave fabric made of untwisted roving and is an important base material for hand lay-up fiberglass. The strength of the roving is mainly in the warp and weft directions. For applications requiring high strength in either the warp or weft, it can also be woven into a unidirectional fabric. This allows for the arrangement of more untwisted rovings in either the warp or weft, resulting in a single warp or single weft fabric.

[0003] The announcement number CN210621061U discloses a glass fiber cloth with a high-strength tensile rib structure, including a first glass fiber cloth yarn, a second glass fiber cloth yarn on the first glass fiber cloth yarn, and the first glass fiber cloth yarn and the second glass fiber cloth yarn are interleaved. The first glass fiber cloth yarn is provided with a spiral first tensile rib bonding layer outside the first glass fiber cloth yarn, and the first tensile rib bonding layer is provided with spirally distributed first yarn reinforcing tensile ribs.

[0004] When ordinary fiberglass cloth is subjected to impact loads, it lacks an effective reinforcing structure, resulting in weak impact resistance and easy fiber breakage, which in turn reduces the overall strength. Therefore, we propose a fiberglass cloth with an internal high-strength tensile rib structure. Utility Model Content

[0005] The purpose of this invention is to provide a fiberglass cloth with an internal high-strength tensile rib structure, which solves the existing problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A glass fiber cloth with an internal high-strength tensile rib structure includes a glass fiber cloth body, which comprises an untwisted roving base cloth, an aramid fiber cloth, and a surface corrosion-resistant coating. The untwisted roving base cloth is disposed on the inner side of the glass fiber cloth body, the aramid fiber cloth is fixedly installed on one side of the untwisted roving base cloth, and the surface corrosion-resistant coating is sprayed on one side of the glass fiber cloth body.

[0008] As a further improvement to the above solution, the outer side of the glass fiber cloth body is provided with glass fiber reinforcing ribs, which are evenly distributed inside the glass fiber cloth body in a grid pattern.

[0009] By adopting the above technical solution, in producing this fiberglass cloth with built-in high-strength tensile reinforcement structure, firstly, untwisted roving plain weave fabric is prepared as the fiberglass matrix according to design requirements. Then, the selected high-strength tensile reinforcements are laid on the fiberglass matrix at predetermined intervals and directions. During the laying process, specialized equipment is used to ensure the accurate positioning of the high-strength tensile reinforcements, and adhesive is used for timely fixation. After the high-strength tensile reinforcements are fixed, the entire fiberglass cloth undergoes preliminary finishing and inspection to ensure a tight bond between the tensile reinforcements and the fiberglass matrix.

[0010] Next, the prepared fiberglass cloth is fed into a coating device, where a protective coating is evenly applied to its surface. During the coating process, the thickness and quality of the coating are strictly controlled to ensure that the coating is uniform, free of bubbles and defects. After coating, the fiberglass cloth is dried and cured to ensure that the coating adheres firmly to the surface of the fiberglass cloth.

[0011] In practical applications, when this fiberglass cloth is used as the substrate for hand lay-up fiberglass, the conventional hand lay-up process is followed. Due to its high strength and good processing adaptability, this fiberglass cloth can fully impregnate and bond with materials such as resins to produce high-quality fiberglass products. During use, this fiberglass cloth can effectively resist various external forces, ensuring stable product performance and extending its service life.

[0012] As a further improvement to the above solution, the surface corrosion-resistant coating is made of epoxy resin and is made of transparent material.

[0013] By adopting the above technical solution, the protective effect of the surface coating effectively prevents the fiberglass cloth from being corroded by the external environment, such as ultraviolet rays and chemicals, thus extending the service life of the fiberglass cloth and improving its reliability in harsh environments.

[0014] As a further improvement to the above solution, the material of the untwisted roving base fabric is an untwisted roving plain weave fabric, in which the glass fibers in the warp and weft directions of the untwisted roving base fabric are interwoven to form a mesh structure.

[0015] By adopting the above technical solution and setting high-strength tensile ribs inside the fiberglass cloth, the strength of the fiberglass cloth in the warp or weft direction is significantly improved, enabling it to withstand greater tensile forces.

[0016] As a further improvement to the above solution, the main body of the glass fiber cloth is made of glass fiber, and the glass fibers are interwoven in the warp and weft directions.

[0017] As a further improvement to the above solution, an adhesive is provided at the connection points of the glass fiber cloth body, the untwisted roving base cloth, the aramid fiber cloth and the glass fiber cloth reinforcement.

[0018] By adopting the above technical solution, the presence of high-strength tensile ribs enhances the ability of glass fiber cloth to resist impact loads; when subjected to impact, the high-strength tensile ribs can disperse the impact force, reduce the breakage of glass fibers, and thus improve the overall impact resistance of glass fiber cloth.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] (1) A glass fiber cloth with a built-in high-strength tensile rib structure of the present invention, wherein the glass fiber cloth body is based on untwisted roving plain weave fabric, and the glass fibers in the warp and weft directions are interwoven to form a stable grid structure, providing basic strength and stability for the glass fiber cloth. According to the actual application requirements, high-strength tensile ribs are set in the warp or weft direction of the glass fiber cloth body. The high-strength tensile ribs are made of high-strength aramid fiber cloth, and the glass fiber cloth tensile ribs are evenly distributed inside the glass fiber cloth body and tightly bonded to the glass fiber cloth body. When the glass fiber cloth tensile ribs are set in the warp direction, the glass fiber cloth tensile ribs are laid along the direction of the warp glass fibers and fixedly connected to the warp glass fibers at certain intervals to ensure that the tensile ribs and the glass fiber matrix work together to bear the tensile force.

[0021] (2) A type of fiberglass cloth with a high-strength tensile rib structure is provided in this utility model. The surface of the fiberglass cloth body is coated with a corrosion-resistant coating. The coating is made of materials with wear resistance, corrosion resistance and weather resistance, such as epoxy resin coating, polyurethane coating, etc. The surface coating can not only protect the fiberglass cloth from the erosion of the external environment and extend its service life, but also improve the surface smoothness of the fiberglass cloth, which is convenient for compounding with other materials in subsequent processing.

[0030] In this embodiment, the surface corrosion-resistant coating 4 is made of epoxy resin and is transparent.
