Abstract

The invention discloses a composite material section bar as well as a preparation method and an application thereof in preparation of a solar photovoltaic module. The composite material section bar comprises fiber reinforcement and resin, wherein the mass ratio of the fiber reinforcement to the resin is (6-9): (1-4), and the fiber reinforcement is the mixture of mixed fibers and mixed fabrics. The composite material section bar can be used for preparing the solar photovoltaic module, has the advantages of lightness, hardness, high mechanical strength, good bending strength, high temperature resistance, low cost, low energy consumption, and very good corrosion resistance and can be applied to regions with environments such as high air temperature, high humidity and high concentration of salt and alkali. The composite material section bar is little influenced by the environments, has good electrical insulation property and can not be subjected to earthing treatment.

Description

technical field [0001] The invention relates to a composite material profile, its preparation method and its application in the preparation of solar photovoltaic components. Background technique [0002] With the process of global industrialization, human's demand for energy is increasing, and the global energy crisis is becoming increasingly severe. As a renewable green new energy source, solar energy has received great attention in various studies on the utilization of solar energy. Especially in recent decades, the dual pressure of energy reduction and environmental pollution has made the solar photovoltaic cell industry develop rapidly. Especially in remote areas such as mountains, beaches, and deserts, solar cells are widely used in order to save expensive transmission lines. [0003] In a specific application, the solar photovoltaic panel is generally embedded in a frame with a notch, and installed on the bracket through the frame. The frame material of existing pho...
