[0035] Referring to Figures 1-3 as shown, this embodiment provides a glass cloth honeycomb core material, including:

[0036] Hexagonal honeycomb part 100 units, several groups of hexagonal honeycomb part 100 units are arranged in sequence along the first direction. Each group of hexagonal honeycomb part 100 units includes several hexagonal honeycomb parts 100 arranged in sequence along the second direction, and two adjacent hexagonal honeycomb parts 100 are connected by a second reinforcing layer 130, and adjacent hexagonal honeycomb part 100 units are connected by a first reinforcing layer 120. The first reinforcing layer 120 is arranged between two adjacent hexagonal honeycomb parts 100 in the first direction;

[0037] Rhombic part 110, the rhombic part 110 is located in the first area surrounded by four adjacent hexagonal honeycomb parts 100, and the four side surfaces of the rhombic part 110 are respectively connected to one side of four adjacent hexagonal honeycomb parts 100;

[0038] A third reinforcing layer 140 is arranged between the rhombic part 110 and the hexagonal honeycomb part 100.

[0039] It can be seen that several hexagonal honeycomb units constitute the main body of the entire honeycomb core material, which is used to provide the main supporting force and stability for the overall structure; the rhombic part 110 is used to fill the gap between the hexagonal honeycomb part 100 units, further enhancing the stability of the overall structure. The rhombic part 110 not only optimizes the force distribution of the material, but also enables the honeycomb core material to effectively disperse stress when subjected to external forces, reducing the phenomenon of local stress concentration, thereby improving the overall load-bearing capacity and impact resistance of the material; the third reinforcing layer 140 has a certain toughness and can absorb part of the energy when the material is impacted or vibrated, reducing the damage to the overall structure.

[0040] Specifically, the first reinforcing layer 120 includes:

[0041] A first reinforcing fiber layer disposed in the middle of two adjacent hexagonal honeycomb portions 100 in a direction perpendicular to the second direction;

[0042] A first adhesive layer located on both sides of the first reinforcing fiber layer, and one side of the first adhesive layer facing the first reinforcing fiber layer is connected to the first reinforcing fiber layer, and the side of the first adhesive layer away from the first reinforcing fiber layer is connected to the hexagonal honeycomb portion 100.

[0043] It can be seen that the material of the first reinforcing fiber layer is preferably glass fiber with high strength and high modulus. These materials not only have excellent mechanical properties, can effectively enhance the connection strength between the units of the hexagonal honeycomb portion 100, but also have a relatively light weight, which helps to reduce the load of the overall structure; the first reinforcing fiber layer is disposed in a direction perpendicular to the second direction, ensuring that it forms a stable bridge between the units of the hexagonal honeycomb portion 100, effectively resisting forces from different directions, and improving the overall stability and durability of the structure; the first is made of a high-performance adhesive, which can ensure the tight combination between the first reinforcing fiber layer and the hexagonal honeycomb portion 100, and avoid delamination or separation during use.

[0044] Specifically, the second reinforcing layer 130 includes:

[0045] A second reinforcing fiber layer 131 disposed in the middle of two adjacent hexagonal honeycomb portions 100 in a direction perpendicular to the first direction;

[0046] A second adhesive layer 132 located on both sides of the second reinforcing fiber layer 131. One side of the second adhesive layer 132 facing the second reinforcing fiber layer 131 is connected to the second reinforcing fiber layer 131, and the side of the second adhesive layer 132 away from the second reinforcing fiber layer 131 is connected to the hexagonal honeycomb portion 100.

[0047] It can be understood that the second reinforcing fiber layer 131 is also preferably glass fiber with high strength and high modulus. Similar to the first reinforcing fiber layer, the second reinforcing fiber layer 131 is arranged in a direction perpendicular to the first direction, ensuring that it forms an effective lateral support between the hexagonal honeycomb portions 100 and enhancing the stability of the structure under lateral loads; the second adhesive layer 132 uses a high-performance adhesive similar to the first adhesive layer to ensure the firm connection between the second reinforcing fiber layer 131 and the hexagonal honeycomb portion 100, preventing loosening or breakage problems that may occur during use.

[0048] Specifically, the third reinforcing layer 140 includes:

[0049] A third reinforcing fiber layer 141 located between the rhombic portion 110 and the hexagonal honeycomb portion 100;

[0050] The third adhesive layer 142 is located on both sides of the third reinforcing fiber layer 141.

[0051] It can be understood that the third reinforcing fiber layer 141 is preferably made of aramid fiber, which can significantly improve the connection strength between the diamond part 110 and the hexagonal honeycomb part 100, and at the same time enhance the toughness of the overall structure. By introducing aramid fiber, not only the bearing capacity of the honeycomb core material under complex stress environments is enhanced, but also its ability to resist environmental erosion is improved, and the service life of the material is extended; the third adhesive layer 142 ensures that the third reinforcing fiber layer 141 can be closely attached between the diamond part 110 and the hexagonal honeycomb part 100, forming a highly integral and gapless reinforcing structure, which not only improves the bonding force between the reinforcing layer and the matrix material, but also optimizes the stress transfer.

[0052] Specifically, the fiberglass honeycomb core material further includes:

[0053] A fireproof layer 143, located between the third reinforcing fiber layer 141 and the third adhesive layer 142, and both sides of the fireproof layer 143 are respectively connected to the third reinforcing fiber layer 141 and the third adhesive layer 142.

[0054] It can be seen that the fireproof layer 143 is used to improve the fire resistance of the fiberglass honeycomb core material, ensuring that the material can maintain a certain structural integrity and stability in extreme environments such as fires. The fireproof layer 143 is mainly composed of materials with excellent high-temperature resistance and flame retardancy, such as inorganic silicates, ceramic fibers or flame-retardant polymer materials. These materials are not easily combustible at high temperatures and can effectively isolate the direct erosion of flames and high temperatures on the internal structure, providing a reliable protection barrier for the overall structure.

[0055] Specifically, the fiberglass honeycomb core material further includes:

[0056] A heat insulation layer, located on the inner side surface of each hexagonal honeycomb part 100.

[0057] It can be seen that the heat insulation layer is used to reduce heat conduction, improve the heat insulation and heat preservation performance of the fiberglass honeycomb core material, and can effectively reduce energy consumption and improve energy utilization efficiency.

[0058] Specifically, the thickness of the hexagonal honeycomb part 100 is 2 to 900 millimeters, the hexagonal honeycomb part 100 is a regular hexagonal honeycomb part 100, and the side length of the hexagonal honeycomb part 100 is 2 to 40 millimeters.

[0059] Specifically, the thickness of the diamond part 110 is 0.04 to 3 millimeters.

[0060] It can be seen that by finely regulating the geometric dimensions and material properties of each layer and component, the comprehensive performance of the glass cloth honeycomb core material has been further optimized; the hexagonal honeycomb part 100, as the basic unit of the structure, has its thickness set between 2 and 900 millimeters, which not only ensures sufficient strength and stiffness but also avoids unnecessary material waste, making the overall structure more compact and efficient; the choice of regular hexagon is not only based on its excellent mechanical stability but also takes into account the convenience of processing and manufacturing, and the side length set between 2 and 40 millimeters takes into account the balance between lightweight and load-bearing capacity.

[0061] It can be understood that the rhombus part 110, as the key part connecting the hexagonal honeycomb part 100 and the outer structure, has its thickness carefully controlled within the range of 0.04 to 3 millimeters. This not only ensures that the rhombus part 110 can withstand forces from different directions but also guarantees the lightweight of the overall structure.

[0062] Specifically, both the second reinforcing fiber layer 131 and the third reinforcing fiber layer 141 are wavy.

[0063] It can be understood that the wavy shape not only increases the surface area of the fiber layer, improves the bonding area with the surrounding materials, and enhances the overall bonding force but also, through its unique geometric shape, effectively disperses stresses from all directions. When subjected to external forces, the wavy structure can guide the stress to gradually release along its curved path, reducing the stress concentration phenomenon and avoiding local damage; the wavy design also endows the reinforcing fiber layer with a certain elasticity, enabling the overall structure to better absorb and disperse energy when subjected to impact or vibration, improving the fatigue resistance and durability of the structure.

[0064] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and its equivalent technologies, the present utility model also intends to include these modifications and variations.
