examples 10 and 11 examine the effect of adding a thermal barrier layer and a uv resistant layer on the mechanical and other properties of the bezel.
TABLE 2 raw material formulations for comparative examples 2 and 3 (in mass percent)
| Raw materials | Comparative example 2(6063) | Comparative example 3(6005) |
| Al | 98％ | 98％ |
| Si | 0.2-0.6％ | 0.6-0.9％ |
| Fe | ≤0.35 | ≤0.35 |
| Cu | ≤0.10 | ≤0.10 |
| Mn | ≤0.10 | ≤0.10 |

Examples 1 to 11 and comparative examples 1 to 3 were subjected to performance tests such as mechanical property tests (tensile modulus, tensile strength, flexural modulus, flexural strength, shear strength, impact strength of simple beam), life test, ultraviolet resistance test, DH3000h test, chemical resistance test and PID resistance test, and the results are shown in the following tables.
Table 3 shows the results of mechanical property tests of examples 1 to 9 and comparative examples 1 to 5
As can be seen from Table 3, the tensile modulus and tensile strength of the frame in example 11 are superior to those of the frame in comparative example 1, and it can be seen that the increase of the adhesion promoter can greatly improve the bonding strength between the fiber reinforced material and the matrix polymer material, thereby improving the mechanical properties and strength of the frame, improving the aging resistance, and prolonging the service life.
Table 4 shows the results of DH3000h test and UV resistance test for examples 1-9 and comparative examples 1-3
Experimental conditions for DH3000h testing: 85% humidity, 85 ℃, DH environment box 3000h (equivalent to outdoor simulated aging for 25 years). As can be seen from Table 4, examples 1-11 all had DH values greater than-5% (-5%, meaning a loss of 5%, and within 5% of the pass range, indicating aging resistance), indicating that the frame properties provided by examples 1-11 meet the desired performance requirements.
Experimental conditions for UV + DH testing: 85% humidity, 85 ℃, 1000h (equivalent to 25 years of outdoor simulated aging) under a DH environment box, and 60h of UV test. As can be seen from Table 4, the UV + DH performance of the frames provided in examples 1-11 meet the performance requirements. In addition, the ultraviolet resistance of the embodiment 9 is better than that of the embodiment 11, the ultraviolet resistance of the embodiment 10 is better than that of the embodiment 11, and after the protective coating is added, the ultraviolet resistance is improved, so that the aging resistance of the frame is improved.

Test conditions for chemical resistance and salt spray test: 5 percent of sodium chloride concentration and relative humidity more than or equal to 85 percent for 96 hours. As can be seen from table 5, the frame surfaces of example 11 and comparative example 1 have microcracks (because of PET or PA being subjected to external force such as rain, snow and storm, the frame is prone to cracking, the product quality is affected, and after the protective coating is added, the frame is not prone to cracking, external force can be resisted, and the service life is greatly prolonged), and because the frame surfaces of example 11 and comparative example 1 do not have the protective coating, the frame cannot be protected, so that the frame is corroded and cracked.
Table 6 shows the results of the PID resistance tests of examples 1 to 9 and comparative examples 1 to 3
anti-PID test conditions: 1500V, 384h, subjects: the back of the double-sided battery of the PID battery piece and the EVA adhesive film of the non-PID-resistant battery piece. As can be seen from table 6, the frames of examples 9, 10, and 11 have higher W after the long-term withstand voltage test than the frame of comparative example 1 and higher attenuation ratio than the frame of comparative example 1 (the larger the absolute value of the attenuation ratio, the worse the aging resistance), and it can be seen that the frames of examples 9, 10, and 11 have better PID resistance than those of comparative examples 1 to 3.
The composite material frame provided by the invention is made of high-strength tensile and bending-resistant materials, so that the whole mechanical load performance can be improved; due to non-conductivity, the PID resistance of the assembly can be improved, and the double-glass double-sided PID is improved more obviously; by adding the protective coating, the ultraviolet resistance and the aging resistance of the frame are improved; the frame cost is low, and the cost of a single tile of the assembly can be reduced; the composite material frame for the photovoltaic module is suitable for stitch welding, tiling, splicing and single-double glass assembly; the method is also suitable for large-size 1.3 x 2.5m photovoltaic modules; the composite material frame for the photovoltaic module can be made into any color so as to meet the color customization requirements of different customers; the composite material frame for the photovoltaic module provided by the invention uses the composite metal material as the corner fittings for connection, is compatible with the current mainstream frame gluing machine and the frame mounting machine, and does not need to be modified for the main equipment frame mounting machine in a module workshop.
