[0044] Raw Materials and Reagents

[0045]

[0046] The fiber passes through the yarn guide plate, resin infiltration box or injection box in turn, the fiber is fully infiltrated in the resin infiltration box or injection box and the air bubbles are squeezed out, and then enters the shaping mold, with appropriate speed and temperature settings, pull out profiles. After the profile leaves the mouth of the shaping die for a certain distance, it is completely cured in the resin curing zone. The pultrusion machine used is a 4-ton crawler pultrusion machine produced by Nanjing Nuoertai Composite Equipment Manufacturing Co., Ltd., and the metering and mixing equipment is an MVP MINI LINK machine provided by MagnumVenus Plastech in the United States.

[0047] The flat-like profile produced by the above pultrusion process has a cross-section of 200mm x 3.2mm. This profile can be cut to the appropriate size and shape as required by the test method. The test results of various m...

Abstract

The present disclosure teaches a member for supporting and / or protecting photovoltaic modules, which comprises fibers extending along an axial direction of the member and plastics as a matrix. The fibers include glass fibers, carbon fibers, metallic fibers and any combination thereof; the plastics include polyurethane. The weight of the fibers is about 30 wt.% ~95 wt.% relative to the total weight of the member. The present disclosure possesses mechanical strength and stiffness similar to aluminum profiles, good electrical insulation properties, resistance to corrosion and a coefficient of thermal expansion compatible with other materials, such as glass, used in photovoltaic modules.

Description

technical field [0001] The invention relates to constituent elements of photovoltaic modules. Background technique [0002] Photovoltaic modules that can directly convert solar energy into electricity can meet the needs of environmental protection and saving non-renewable energy. However, the popularity of photovoltaic modules depends on its cost-effectiveness, including the conversion efficiency of photovoltaic cells, the production, transportation, and installation costs of photovoltaic modules, and the service life of photovoltaic modules. [0003] A photovoltaic module generally consists of the following components: a front sheet, a back sheet, one or more interconnected photovoltaic cells located therein, encapsulation material, and members for further protection and / or support of the photovoltaic module. [0004] The front plate is generally made of transparent glass, especially suitable is tempered glass with low iron content, which has good light transmittance for l...
