Carbon fiber fixtures are mainly made of high-quality carbon fiber composite material combined with special weather-resistant resin. Different from traditional metal and aluminum alloy photovoltaic fixture materials, carbon fiber composite material has the core advantages of low density, high strength and excellent toughness, as well as excellent corrosion resistance and aging resistance. Its special fiber laminated structure can not only effectively reduce the overall weight of the fixture, reduce the installation load and construction difficulty of photovoltaic modules, but also withstand the erosion of complex outdoor environments and external extrusion, and is not easy to break, deform or rust. This material can resist the influence of harsh environments such as sun and rain, humidity and heat, salt spray, and can also cope with thermal expansion and contraction caused by temperature changes, avoid loose fixture structure, extend the service life, adapt to various photovoltaic installation scenarios, and provide stable structural support for photovoltaic systems.
