Referring to FIG. 1 , an anti-collision composite hull 100 according to an embodiment of the present invention includes a hull 110 and a protective composite structure 120 and a super hybrid composite 130 . The hull 110 is primarily made of a composite material.

The protective composite structure 120 is disposed above the waterline of the outer surface of the hull 110. Since the area above the waterline of the outer surface of the hull 110 is an area where the wear-resistant collision-resistant composite hull 100 is more likely to collide with other ships, the protective composite structure 120 is only disposed above the waterline, and the wear-resistant and crash-resistant composite hull is improved. At the same time as the wear resistance of 100, the manufacturing cost can be largely saved, and the hull 110 can be increased less in its own weight. Of course, if the cost and the weight of the hull 110 are not considered, the protective composite structure 120 may be provided in all areas of the outer surface of the hull 110 for ease of manufacture.

The protective composite structure 120 includes a wear layer 121, a cord fabric layer 123, a metal cloth layer 125, and a water repellent layer 127 joined together. The wear layer 121 primarily increases the wear resistance of the outermost surface of the protective composite structure 120. The cord fabric layer 123 is primarily used to increase the toughness of the protective composite structure 120. The metal cloth layer 125 mainly serves as a rigid transition. When the hull is hit by other ships, the protective composite structure 120 is not easily damaged due to too much rigidity transition. The waterproof layer 127 is mainly used for waterproofing and anti-corrosion.

The wear layer 121 is located outside the cord fabric layer 123. The wear resistant layer 121 is a polyurea layer. The wear layer 121 can be formed by in-mold forming, that is, after the mold release agent is applied in the formed hull mold, the wear-resistant layer 121 is sprayed.

It should be noted that, according to different protection strength requirements, the metal cloth layer 125 and the cord fabric layer 123 may be multiple layers, and may be alternately arranged at intervals.

The waterproof layer 127 is located on the outer surface of the hull 110. The waterproof layer 127 is formed on the metal cloth layer 125 in a manner of in-mold molding. Specifically, in the present embodiment, the waterproof layer 127 is a resin-rich layer.

Referring to FIG. 2, the super hybrid composite 130 is disposed on a region below the waterline of the outer surface of the hull 110. The super hybrid composite 130 includes a fiber reinforced composite plastic layer 131 and a metal fiber layer 133 sandwiched in the fiber reinforced composite plastic layer 131. . The metal fiber layer 133 may be a plurality of layers. Specifically, in the embodiment, the resin is introduced by a vacuum assisted introduction process, and after high temperature post-curing treatment, the temperature of the high temperature treatment is generally 90 degrees; the metal fiber layer 133 is subjected to the interface treatment, and then the fiber reinforced composite plastic layer 131 is The other fibers are formed after supermixing, and the "interfacial treatment" is to treat impurities on the surface of the metal fibers with an acid (hydrochloric acid or acetic acid). The fiber reinforced composite plastic layer 131 may be a glass fiber reinforced epoxy resin composite material, and a metal fiber treated with an acid (hydrochloric acid or acetic acid) as a reinforcing material in the glass fiber reinforced epoxy resin composite material may increase the elasticity of the composite material. Modulus, increasing stiffness and tensile strength.

The above-mentioned super hybrid composite material 130 has easy availability of raw materials, low cost, less weight increase, and significantly improved wear resistance.

The wear resistance of the wear-resistant and crash-resistant composite hull 100 is further improved.

Referring to FIG. 3, a method for manufacturing a wear-resistant and crash-resistant composite hull according to an embodiment of the present invention includes the following steps:

In step S201, a hull mold is provided.

Step S202, forming a super hybrid composite material in a cavity below the cavity of the hull mold corresponding to the water line of the hull body to be formed, the super hybrid composite material comprising the fiber reinforced composite plastic layer and the fiber reinforced composite plastic layer a layer of metal fibers inside.

Referring to FIG. 4 , in the embodiment, the ultra-hybrid composite material 130 is integrally formed with the hull 110 by using an “in-mold lamination molding process”, and specifically includes the following steps:

In step a, the metal fiber is subjected to an interface treatment. Specifically, the surface of the metal fiber is wiped with an acid reagent or soaked with a metal fiber such as hydrochloric acid or acetic acid. The "interfacial treatment" means the treatment of impurities on the surface of the metal fiber with an acid (hydrochloric acid or acetic acid). The purpose of interfacial treatment of metal fibers is to activate the surface energy of the metal fibers, introduce polar groups on the surface of the fibers, and improve the adhesion of the metal fibers to the matrix resin, thereby improving the material rigidity. The metal fiber is stainless steel or other water and corrosion resistant alloy. The functional filler is a nano-reinforced wear-resistant filler.

If the metal fiber has been treated by the prior interface, or if a polar group is present on the surface of the metal fiber, and the adhesion of the metal fiber to the matrix resin is good, step a may be omitted.

In step b, the fiber used for the interface treated metal fiber or fiber reinforced composite plastic is dipped or laid into a prepreg and then laid.

Specifically, in the embodiment, the step b is dipping the fiber used for the metal fiber or the fiber reinforced composite plastic after the interface treatment, including:

In step b1, the fibers used in the metal fiber and the fiber reinforced composite plastic are laminated. The fibers of the metal fiber and the fiber reinforced composite plastic layer are laid in a manner of inter-layer mixing or/and inter-layer mixing. The fibers used in the metal fiber and fiber reinforced composite plastic layer can be inter-layered or inter-layered, and the intra-layer mixing is to mix a plurality of fibers in the same layer, and the inter-layer mixing is to divide the plurality of fibers into a plurality of layers. The ultra-hybrid composite looks like a whole laminate structure. Proper use of hybrid fibers and their proportions, and then through the correct and reasonable layering design of the product. Super hybrid composites are resistant to impact, abrasion and corrosion.

The fiber reinforced composite plastic layer may be a glass fiber reinforced epoxy resin composite material, and a metal fiber treated with an acid reagent (hydrochloric acid or acetic acid) may be added to the glass fiber reinforced epoxy resin composite material to form a reinforcing material, which may be added. The modulus of elasticity of the composite increases stiffness and tensile strength. The fibers used in the fiber reinforced composite plastic layer may also be aramid or a mixture of glass fibers and aramid.

The metal fibers form a layered structure, that is, a metal fiber layer is formed. The metal fiber layer is formed of metal fibers. The metal fiber is sandwiched in the fiber reinforced composite plastic layer. Metal fibers are fibers of stainless steel or other water and corrosion resistant alloys. The functional filler is a nano-reinforced wear-resistant filler. The metal fiber layer may be a single layer or multiple layers depending on the need for different stiffness.

The above design can effectively exert the functional properties of the reinforcing fiber, realize the functional distribution of the whole material, and ensure the super-hybrid composite material has the advantages of strength, modulus, wear and impact resistance, and low cost. And super-hybrid composite materials are suitable for complex environments such as impact, wear and corrosion.

Wherein, the laminating and laminating process is: in the mold for brushing the release agent, each layer is separately dipped according to a specific matrix formula, and then laminated according to the above-mentioned "ply structure design" to achieve a predetermined number of layers. crafting process.

In step b2, the resin is introduced into the resin by a vacuum resin introduction process to form a fiber-reinforced composite plastic layer and a metal fiber layer sandwiched in the fiber-reinforced composite plastic layer. "Vacuum Resin Induction Process" (VRIP), also known as "Vacuum Assisted Resin Diffusion Molding Process (VARIM)", or "Vacuum Assisted Resin Transfer Molding Process (VARTM)". The principle of the process is to inject resin into a pre-formed reinforcing material by means of a vacuum drive, the mold consisting of a flexible mold and a rigid mold half. Since the reinforcing material is pressed by a vacuum and the penetration speed of the resin is generally slow, it is necessary to use a flow guiding medium to inject the resin into the preformed reinforcing material. The flow guiding medium extends into the reinforcing material and the resin is injected into the reinforcing material along the flow guiding medium. The flow guiding medium can be a guide cloth or a draft tube.

In other embodiments, the step b is a step of depositing the fibers used for the interface treated metal fiber and the fiber reinforced composite plastic layer into a prepreg, and the step b includes: first, the metal fiber and the fiber reinforced composite. The fibers used in the plastic are laminated to form a reinforcing material. The reinforcing material is then dipped into the glue tank for dipping. Excess resin is extruded to make a prepreg with a lower gel content. Finally, the winding is stored at a low temperature and stored for use.

In step c, a pressure-holding curing treatment is performed. Referring to FIG. 4 and FIG. 5, the flexible curing structure is used for curing, and the flexible curing structure is an element that can change shape according to external constraints. The flexible curing structure includes a flexible hot water bottle and a pressurizing member. The middle portion of the flexible hot water bottle 310 forms a recess so that the hot water of the flexible hot water bottle 310 can form a circulation loop. Thereby, the heating efficiency is accelerated. Of course, the hot water of the flexible hot water bottle can be connected to the external heating system to continuously heat the circulating water. In addition, if the molding pressure is insufficient, the pressing member is placed on the concave portion and the periphery of the flexible hot water bottle to increase the quality of the flexible curing structure and increase the curing pressure. The pressure member can be a sandbag 320 or other weight to increase the pressure of the flexible hot water bottle against the reinforcing material.

The flexible hot water bottle 310 (which may also be a hot water bottle) may also be subjected to in-mold pressure forming for a flexible sand bag. The advantage of using a flexible hot water bag or a flexible sand bag is that it can overcome the disadvantages of using a large pressure tank and a large volume of the mechanical press, and the drawbacks of matching the shape of the mold.

The pressure curing can be cured at room temperature or high temperature. It is necessary to ensure that the curing temperature in step c is higher than the temperature in step b. It can be understood that when step b is a low temperature technique, step c corresponds to curing at room temperature. When step b employs a normal temperature technique, step c is cured at a high temperature.

Specifically, in the present embodiment, the flexible hot water bottle 310 is used and hot water is provided to provide temperature conditions. The hot water temperature is 80-90 degrees, the curing temperature is 80-90 degrees, and the curing time is 2-4 hours. After the super-hybrid composite material 130 after the pressure-hardening treatment, the laminated layers are flat and wrinkle-free, and there is no bubble with a diameter larger than 0.5 mm between the layers, which increases the rigidity of the super hybrid composite 130. Please refer to Figure 6. The composite material is formed in relation to temperature and time. In the case of a general composite material, it is formed by a high-pressure molding machine, and an additional heating tool is required to heat the mold on the high-pressure molding machine to heat the composite material. However, the present invention can be formed by using the flexible hot water bottle 310 for low pressure molding, and does not require an additional heating tool, that is, pressurization and heating, which not only meets the temperature requirement, but also effectively increases the pressure, can improve the molding efficiency, and save the molding cost. Compared with the traditional method of heating copper pipes on the mold, the heating method is economical, the heat is uniform, and the heating efficiency is doubled, so that the desired heating effect can be achieved.

The super hybrid composite material 130 is disposed in the cavity of the mold 300. The flexible hot water bottle 310 is placed in the mold 300 and abuts on the super hybrid composite 130. The mold 300 is brushed with a release agent to facilitate demolding in the future.

In step d, a high-temperature post-cure molding process is performed. Specifically, in the present embodiment, the high temperature is 80 to 95 degrees, and the post curing time is more than 8 hours. Through the post-cure treatment, the strength and rigidity of the composite material can be significantly improved, thereby reducing the weight. This is a technological innovation in the domestic composite material manufacturing process, and the process advantages are remarkable.

In step e, mold release is performed on the super hybrid composite material after high temperature curing. The mold 300 is peeled off, and the super-hybrid composite material 130 after the curing molding is exposed. In the above method for preparing a super hybrid composite material, the metal fiber is interposed in the fiber reinforced composite plastic layer, and the rigidity and stretchability of the metal fiber can be better reflected. In the above method for manufacturing a super hybrid composite material, the raw material is inexpensive and convenient to be obtained, and the in-mold repressurization is completely realized. Moreover, vacuum and re-pressurization double insurance, enhance the process pressure, can ensure uniform and continuous rich resin layer, uniform dipping of fiber fabric, ensure that the laminated layers are flat and wrinkle-free, and the diameter between layers is not more than 0.5. Mm bubble, increasing material stiffness. After testing, the super-hybrid composite material has an impact resistance improvement of 2-3 times and a wear resistance of 5-8 times compared with the ordinary glass fiber composite material.

The ultra-hybrid composite material 130 produced by the above-described method for manufacturing a super hybrid composite material is easy to obtain, has low cost, small weight, and has significantly improved performances such as impact resistance and wear resistance. The super hybrid composite material 130 is disposed on a region below the waterline of the outer surface of the hull (not shown), and the metal fiber layer is located in the fiber reinforced composite plastic layer away from the side of the hull. Since the super hybrid composite material 130 has good rigidity and tensile strength, the crash resistance, wear resistance and corrosion resistance of the hull under the water line are improved.

It can be understood that the above-mentioned super hybrid composite material 130 can be applied not only to ships but also to aircraft, motor vehicles and the like, and can also improve the crashworthiness, wear resistance and corrosion resistance of aircraft, motor vehicles and the like.

In the above-mentioned method for molding the super hybrid composite material 130, the raw material is inexpensive and convenient to be obtained, and the in-mold repressurization is completely realized. Moreover, vacuum and re-pressurization double insurance, enhance the process pressure, can ensure that the resin-rich layer is even and continuous, the fiber fabric is evenly dipped, and the laminated layers are ensured to be flat and wrinkle-free, and there is no diameter greater than 0.5 mm between the layers. Bubbles increase material stiffness. After testing, the super-hybrid composite material has an impact resistance improvement of 2-3 times and a wear resistance of 5-8 times compared with the ordinary glass fiber composite material.

If the protective composite structure 120 is further formed, the method for manufacturing the wear-resistant and crash-resistant composite hull of the embodiment of the present invention further includes the following steps:

In step S203, a layer of wear-resistant material is sprayed on the inner wall of the cavity of the hull mold coated with the release agent corresponding to the waterline of the hull of the wear-resistant and crash-resistant composite material to form a wear-resistant layer. Specifically in the present embodiment, the wear resistant layer may be a polyurea layer.

In step S204, at least one layer of cord fabric is laid on the wear layer, and a layer of polyurea is sprayed on at least one layer of the cord fabric to form a cord fabric layer. The cord fabric can be multi-layered depending on the need for different toughness.

In step S205, at least one layer of metal cloth is laid on the cord fabric layer, and a layer of polyurea is sprayed on at least one layer of metal cloth to form a metal cloth layer. The metal cloth may be a steel mesh or a high-hardness alloy mesh. The metal cloth can be multi-layered depending on the rigidity requirements.

In step S206, if it is necessary to form a multilayer cord fabric layer or/and a plurality of metal cloth layers, the step of forming the cord fabric layer or/and the step of forming the metal cloth layer is repeated. The metal cloth layer and the cord fabric layer may be alternately arranged according to different protection strength requirements.
