Description

A glass fiber composite stitch-woven felt Technical Field

[0001] This utility model relates to the field of glass fiber composite stitch-woven felt technology, specifically a glass fiber composite stitch-woven felt. Background Technology

[0002] Fiberglass composite stitch-woven mat is a high-performance composite material made from fiberglass as the base material through a special stitch-weaving process. This material not only inherits the advantages of fiberglass, such as high strength, low elongation, high temperature resistance, and good chemical stability, but also further enhances the interlayer strength and overall integrity of the material through its stitch-woven structure. Due to its excellent mechanical properties and adaptability, fiberglass composite stitch-woven mat is widely used in aerospace, automotive manufacturing, shipbuilding, wind power generation, and other fields, especially excelling in products requiring lightweight and high strength. Furthermore, its ease of processing and molding makes it an ideal choice for many industrial applications.

[0003] In existing technologies, after the fiberglass composite stitched mat is laid, adjacent pieces are bonded together solely with adhesive. Due to the lack of a physical interlocking mechanism, this adhesive-based connection may lead to peeling or failure under long-term loads, environmental changes, or external impacts, especially in high-stress applications. This limitation restricts tighter bonding and uniform force transmission between materials, potentially affecting the mechanical properties and lifespan of the final product. Summary of the Invention

[0004] The purpose of this invention is to provide a glass fiber composite stitch-woven felt to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fiberglass composite stitch-woven felt, comprising a fiber felt body, a splicing mechanism fixedly installed on the outside of the fiber felt body, the splicing mechanism comprising a rectangular sleeve, two sets of connected outer edges of the rectangular sleeve forming a splicing edge, a plurality of protrusions fixedly installed on one side of the splicing edge, the other two sets of connected outer edges of the rectangular sleeve forming a locking edge, a plurality of grooves being provided inside the locking edge, a rolled edge being movably installed on the top of the locking edge, and a flocking layer being provided on the surface of both the locking edge and the grooves.

[0006] Preferably, the protrusion and the groove are both in the shape of a keyhole.

[0007] Preferably, the fiber felt body includes a unidirectional fiber layer, a stitching thread, a continuous fiber layer, and a chopped fiber layer. The unidirectional fiber layer, the continuous fiber layer, and the chopped fiber layer are sewn together by the stitching thread. The continuous fiber layer is disposed at the bottom of the unidirectional fiber layer, and the chopped fiber layer is disposed at the bottom of the continuous fiber layer.

[0008] Preferably, a number of self-healing components are fixedly installed inside the unidirectional fiber layer, the continuous fiber layer, and the chopped fiber layer.

[0009] Preferably, the self-healing component includes a photosensitive capsule shell, the inside of which is provided with a curing agent and epoxy resin, and a partition is fixedly installed inside the photosensitive capsule shell, with the epoxy resin and curing agent respectively disposed on the upper and lower sides of the partition.

[0010] Preferably, the fiber felt body further includes a conductive shielding layer, which is disposed between the continuous fiber layer and the chopped fiber layer.

[0011] Preferably, the fiber felt body further includes a protective layer, which is disposed on top of the unidirectional fiber layer.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the glass fiber composite stitch-woven felt;

[0013] 1. When used for large-area laying, the splicing edge of one set of composite felt can be locked with the locking edge of another set of composite felt, allowing a stable mechanical connection between adjacent composite felts, enhancing the system's anti-peeling and load-bearing capacity, simplifying the construction process, reducing the difficulty of alignment and fixing, making the laying work faster and more accurate, and a large number of composite felts can form a continuous and solid whole, effectively improving the performance and durability in the final application.

[0023] Example 1

[0024] Please refer to Figures 1-3. This utility model provides a technical solution: a fiberglass composite stitched felt, including a fiber felt body 1. A splicing mechanism 2 is fixedly installed on the outside of the fiber felt body 1. The splicing mechanism 2 includes a rectangular sleeve 201. Two sets of outer edges of the rectangular sleeve 201 are connected to form a splicing edge. Several protrusions 202 are fixedly installed on one side of the splicing edge. The other two sets of outer edges of the rectangular sleeve 201 are connected to form a locking edge. Several grooves 203 are provided inside the locking edge. A rolled edge 204 is movably installed on the top of the locking edge. A flocked layer 205 is provided on the surface of the locking edge and the grooves 203. The protrusions 202 and the grooves 203 are identical in shape and are both lock hole-shaped. The circular part of the lock hole shape can provide a larger contact area to ensure a tight fit between the two parts, thereby improving the stability and strength of the overall structure. The rectangular part can effectively restrict lateral movement and prevent the parts from sliding or misaligning when subjected to force.

[0025] This utility model of fiberglass composite stitched felt: When used in large-area laying, the splicing edge of one set of composite felts can be locked with the locking edge of another set of composite felts, allowing for a stable mechanical connection between adjacent composite felts. This enhances the system's anti-peeling and load-bearing capacity, simplifies the construction process, reduces the difficulty of alignment and fixing, and makes the laying work faster and more precise. A large number of composite felts can form a continuous and solid whole, effectively improving the performance and durability in the final application. Specifically, the splicing edge and locking edge are mechanically connected by inserting the protrusion 202 into the groove 203, reducing the difficulty of alignment and fixing. Then, the connecting surface of the protrusion 202 and the groove 203 is covered by the rolled edge 204, reducing the connection seam and improving the overall aesthetics. The flocked layer 205 increases the friction between the locking edge and the surface of the groove 203, significantly improving the stability of the connection between adjacent composite felts, ensuring that they are more tightly bonded together during the laying process, and reducing the risk of slippage or separation due to external forces.

[0026] Example 2

[0027] Please refer to Figures 1-3. As another preferred embodiment of this utility model, the difference from Embodiment 1 is that the fiber felt body 1 includes a unidirectional fiber layer 101, a stitching thread 102, a continuous fiber layer 103, and a chopped fiber layer 104. The unidirectional fiber layer 101, continuous fiber layer 103, and chopped fiber layer 104 are sewn together by the stitching thread 102. The continuous fiber layer 103 is disposed at the bottom of the unidirectional fiber layer 101, and the chopped fiber layer 104 is disposed at the bottom of the continuous fiber layer 103. The unidirectional fiber layer 101 serves as the main body of the fiber felt, bearing the main tensile and bending loads. The continuous fiber layer 103 provides shear and torsional resistance, while the chopped fiber layer 104 improves formability and local stiffness. The fiber felt body 1 also includes a conductive shielding layer 105, which is disposed between the continuous fiber layer 103 and the chopped fiber layer 104. The conductive shielding layer 105 reflects and absorbs electromagnetic waves. The fiber felt body 1 also includes a protective layer 106, which is disposed on top of the unidirectional fiber layer 101. The protective layer 106 effectively resists mechanical wear, impact, and chemical corrosion, thus extending the service life of the fiber felt.

[0028] Example 3

[0029] Please refer to Figures 1-4. As another preferred embodiment of this utility model, the difference from Embodiment 1 is that several self-healing components 3 are fixedly installed inside the unidirectional fiber layer 101, the continuous fiber layer 103, and the chopped fiber layer 104. Each self-healing component 3 includes a photosensitive capsule shell 301, which contains a curing agent 304 and an epoxy resin 303. A partition 302 is fixedly installed inside the photosensitive capsule shell 301, separating the epoxy resin 303 from the epoxy resin 303. Curing agent 304 prevents epoxy resin 303 from solidifying inside the photosensitive capsule shell 301. Epoxy resin 303 and curing agent 304 are respectively placed on the upper and lower sides of the partition 302. When the fiber felt body 1 is damaged, the photosensitive capsule shell 301 is exposed to sunlight and cracks, releasing the epoxy resin 303 and curing agent 304 inside. The epoxy resin 303 and curing agent 304 fill the damaged area, mix and solidify to fill the cracks, achieving self-repair. It can restore more than 90% of the mechanical properties of the material, significantly extend its service life, and reduce maintenance costs.
