[0042] Example one
[0043] See image 3 , Figure 4 As shown, the embodiment of the present invention provides an upper crossbeam of a carbon fiber composite material automobile water tank. The upper crossbeam structure of the water tank is optimized. Specifically, the upper crossbeam 1 structure of the water tank includes at least: a beam body 1.1, a beam wing 1.3, and a second beam. One wing 1.5, second wing 1.7, side 1.9, beam crown 1.11; the selected material is carbon fiber T300+5028 resin composite material, the thickness is about 3.0mm, and the weight is about 0.4kg; the carbon fiber (CF) is fiber Shaped carbon material with a carbon content of more than 90%. It not only has the inherent characteristics of carbon materials, but also has the soft and processability of textile fibers, and has corrosion resistance, good heat resistance, light weight, high strength and high elasticity. Based on fiber grade and directionality, it can even reach the similar strength of steel. ...
Example Embodiment
[0045] Example two
[0046] In order to realize the above structural design, an embodiment of the present invention provides a method for manufacturing an upper crossbeam of a carbon fiber composite material automobile water tank. Specifically, as a preference, the manufacturing method includes at least: 1) material selection; 2) layering; 3) sealing; 4) vacuuming; 5) resin introduction; 6) curing and demoulding process steps; wherein
[0047] Step 1) Selection of materials;
[0048] The carbon fiber composite material is composed of a multi-layer carbon fiber material as a reinforcement and a resin as a matrix. The multi-layer carbon fiber material is selected from Toray T300 carbon fiber fabric, and the resin is selected from the medium and low temperature fast curing 5028 epoxy resin system. Raw materials, the content of carbon fiber fabric (weight percentage, the same below) is 50-60%, and the content of epoxy resin material is 40-50%;
