Abstract

A high-performance composite material used for a photovoltaic supporting bracket includes, by weight, the following components: 30-100 parts of resin, 1-10 parts of a hyperbranched polymer, 20-40 parts of a filler, 0.1-1.5 parts of a curing agent, 0.3-3 parts of an ultraviolet screening agent, 30-90 parts of basalt unidirectional fibers, and 10-30 parts of basalt multiaxial cloth. The invention simultaneously discloses a preparation method of the composite material. A pultrusion process is adopted; the basalt unidirectional fibers and the basalt multiaxial cloth are a reinforcement body; matrix resin is immersed by a dipping process; premoulding and a moulding die are performed; and gelling, curing and post-curing are performed under conditions of an appropriate temperature and traction toprepare the high-performance composite material suitable for the photovoltaic supporting bracket. The composite material is high and strong in lightweight, is high in specific modulus and specific strength, is good in weather resistance, is very low in cost, has the material density of 1.8 g / cm<3> after moulding, is very good in toughness, and is not damaged when the material is subjected to strong wind or impact of an external force.

Description

technical field [0001] The invention belongs to metal supports, in particular to a high-performance composite material for photovoltaic supports and a preparation method thereof. Background technique [0002] With the rapid development of industry and society, the petrochemical energy in nature is becoming increasingly scarce, and environmental pollution is becoming more and more serious. Clean energy is becoming more and more popular. As ubiquitous solar energy occupies an important position in the field of new energy. Most of the current photovoltaic supports are made of steel. The structure of this support is relatively complicated, the production cost is relatively high, and it is difficult to compare the installation and disassembly, and it is difficult to change the arrangement of the photovoltaic support. Contents of the invention [0003] In order to solve the defects of expensive metal brackets in the prior art, heavy weight, and difficult installation and disas...
