Problems solved by technology

[0005] In the published patents and literatures that use compatible materials to prepare solar module frames, such as Chinese patent CN103205004A, the fiber reinforcement used is a mixture of mixed fibers and mixed fiber fabrics. This method can achieve vertical reinforcement of solar module frames. The purpose of the strength of the fiber direction, but the process is more complicated, and the longitudinal strength is not very high; in the Chinese patent CN102093659, continuous fiber cloth, continuous fiber unidirectional tape, long fiber mat or the combination of the two are used to strengthen the resin, the same It can achieve the purpose of enhancing the lateral strength, but the process is more complicated

Abstract

The invention discloses a fiber-felt-reinforced composite material solar energy assembly frame and a preparation method thereof and aims to solve a problem of poor strength of a solar energy assembly frame structure in the prior art. In the invention, two solar energy assembly frames are jointed to each other to form a regular rectangular outer side, wherein the two solar energy assembly frames can be produced at the same time. Meanwhile, during a moulding process, the external side of unidirectional fiber bundles arranged in a preset shape is wrapped by fiber felt, and then the solar energy assembly frame is sent to a heating die for pultrusion. By means of cooperation with a pulling apparatus at the outer side and a cutting machine for cutting the material, the required solar energy assembly frame is formed. By means of addition of the continuous fiber felt at the outer side, the transversal strength of the solar energy assembly frame can be enhanced so that the solar energy assembly frame is excellent in comprehensive performances. By means the production of the two frames at the same time, the preparation method is increased in production efficiency, is simplified in processes and can promote an application of the composite material in photovoltaic field.

Description

technical field [0001] The invention relates to a molding process of a composite material, in particular to a method for preparing a frame of a solar module made of a fiber felt reinforced composite material. 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 frames of solar modules are made of aluminum alloy, which is widely used because of its light weight, strong strength and firmness, and corrosion resistance. However, research in re...
