[0020] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] like Figure 1 A method for preparing a high-strength lightweight material is shown, and the preparation process is as follows:

[0022] Step 1: colloid coating, evenly coating the colloid on the surface of the substrate;

[0023] Step 2: Winding the fiber line, evenly winding the drawn fiber line on the substrate;

[0024] Step 3: Heating and curing: heating the colloid while winding the fiber line, and curing the fiber line and colloid in real time to form a hard shell attached to the substrate;

[0025] Step 4: multi-layer winding, repeating the preparation process of steps 2 and 3 to wind multiple layers of fiber lines on the substrate.

[0026] In this embodiment, in step 1, the colloid is made of high-strength epoxy adhesive with toughness.

[0027] In this embodiment, the substrate is made of the same material as the colloid, and an infrared absorber may be added to the colloid. The infrared absorber can be added in a certain proportion based on the laser wavelength range of the selected laser curing device. In this embodiment, the absorption wavelength range is 800-1100 nm, the initial curing temperature of the colloid is set at 130-150 degrees Celsius, and the colloid coating thickness is controlled within 1 mm for optimal curing. In this manner, stable irradiation for approximately 3-10 seconds is sufficient to complete the curing of the corresponding colloid.

[0028] In this embodiment, in step 1, the base material is selected from any one of round pipe piles, square pipe piles or special-shaped pipe piles.

[0029] In this embodiment, in step 2, the fiber line is made by drawing any one of quartz optical fiber, glass fiber, and high-temperature resistant carbon fiber. In order to increase the strength of the fiber line, Kevlar fiber (bullet-proof fiber) can be added during the drawing process.

[0030] In this embodiment, in step three, a laser curing device capable of temperature monitoring and regulation is selected to heat the colloid.

[0031] In this embodiment, two adjacent layers of fiber lines are wound in a cross or interlaced manner.

[0032] This embodiment is described using a tubular substrate. Figure 2 As described above, by reinforcing the base material layer by layer in a winding and curing manner, the overall shape material can provide sufficiently strong rigidity and toughness after reaching a certain thickness requirement. Due to the use of lightweight fiber materials and low-density colloids, the overall material strength can reach the rigidity and strength of metal materials.

[0033] Among them, the colloid can be sprayed using a ring-shaped multi-nozzle flat-mouth spray brush device, which can effectively control the amount of glue and the thickness of the spraying; the winding machine used for winding the fiber line can be modified from a 3-head or multi-head winding machine device. By modifying the winding unit, the drawn fiber line can be evenly wound on the substrate to increase the rigidity of the substrate; the colloid is heated by a laser curing device, and the colloid in the winding process is heated in real time through uniform irradiation of a variable spot laser lens, and the fiber line and colloid are cured in real time to form a hard shell attached to the surface of the substrate. Infrared temperature monitoring is added during the irradiation process to adjust the laser irradiation intensity in real time. In order to improve the curing effect, the relationship between the colloid coating equipment and the laser curing equipment should be coordinated to improve the gluing efficiency while ensuring the stability of the colloid heating and curing; the fiber line should be wound in 8 to 10 layers. The thinner the thickness of each winding, the smaller the size of the wound material and the lighter the weight.

[0034] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
