Problems solved by technology

[0006] The purpose of the present invention is to use short fiber reinforcement to solve the problem of insufficient structural strength of the pultruded composite solar module frame. During the pultrusion process, short fibers are added to the resin impregnated material and dispersed in the resin evenly, so that the obtained profile is short. Fibers form lap joints between continuous fibers to make up for the lack of performance of continuous fiber-reinforced thermoplastic composites in the vertical fiber direction, making it more excellent in performance. The process is simple and easy to operate, and the cost will not increase significantly. The result is easy to control. Flexible adjustment to actual needs

Abstract

The invention discloses a short-fiber-reinforced pultrusion composite material solar energy assembly frame, which is characterized by being produced through a pultrusion method and being composed of following components, by volume: 5-10% of short fibers, 50-80% of continuous fibers and 10-40% of resin. The invention also discloses a preparation method of the solar energy assembly frame. In the method, a short fiber reinforcement body is added for solving a problem of insufficient strength in the vertical direction of the fiber when a continuous reinforced pultrusion composite material is used as the solar energy assembly frame. The continuous fiber is impregnated in the resin mixture, in which 5-10% by volume of the short fibers is dispersed homogeneously, and then the impregnated continuous fiber is injected into a die for obtain the solar energy assembly frame through pultrusion. The short fibers can form an overlap joint structure among the continuous fiber so that the performance in the vertical direction of the fibers in the material can be improved. Not only is the excellent performance in the direction in parallel with the fibers ensured, but also an excellent mechanical performance in the vertical direction of the fibers can be ensured at the same time.

Description

technical field [0001] The invention relates to a pultrusion composite material profile, in particular to a short fiber reinforced pultrusion composite material solar module frame and a preparation method thereof. Background technique [0002] With the deteriorating environmental situation, people's demand for clean energy is increasing, and solar energy, as a renewable resource, has received more and more attention. Solar energy resources have played a certain role in daily life, for example, the use of solar water heaters and photovoltaic power generation. The materials used in solar equipment are exposed to sunlight for a long time during use, so they need to have good weather resistance and UV resistance to improve the durability and reliability of the equipment. [0003] At present, most of the materials used for solar module frames are aluminum alloy materials. However, the use of aluminum profiles to produce solar cell module frames has the following problems: low pr...
