Fiber Reinforced Composite Pultrusion Profile Technology

 

Brief Introduction of Achievements

 

Fiber-reinforced composite pultruded profiles are composite materials made of fiber-reinforced materials (such as glass fiber, carbon fiber, basalt fiber, aramid fiber, etc.) and resin matrix materials (such as epoxy resin, vinyl resin, unsaturated polyester resin, polyurethane resin, etc.) through pultrusion (as shown in the figure below).

 

Compared with traditional building materials (such as steel and concrete), pultruded profiles have the advantages of light weight, high strength, corrosion resistance, and low carbon. The maintenance cost of pultruded profile structures throughout their life cycle is also much lower than that of similar steel and concrete structures. Pultruded profiles have shown strong application potential in civil engineering, new energy, machinery and automobile manufacturing, aerospace, and other fields.

 

 

 

Based on the characteristics of pultruded profile materials, the team proposed an integrated design method of “process-material-structure”, and developed products including: external frame beams for high-rise buildings, urban rail transit sound barriers, photovoltaic frames and brackets, photovoltaic carports, container houses, etc.

 

The team carried out technical consulting work such as molding process and formula design, material performance testing, structural design and optimization, and engineering construction and maintenance.

 

 

Application Fields

 

Application fields of pultruded profiles include: civil engineering (such as pedestrian overpasses, frame structures, etc.), new energy (such as wind power, photovoltaics, etc.), machinery manufacturing (such as cooling towers, medical non-magnetic structures, etc.), and automobile manufacturing (such as anti-collision beams, battery packs, etc.). Pultruded profiles have significant advantages in achieving lightweight structures, high bearing capacity reserves, high durability, and low carbon emissions.

 

Features and Advantages

 

External Frame Beams for High-rise Buildings:

The weight of the structure is reduced by 75% compared to steel structures; carbon emissions are reduced by 73%; construction measures costs are greatly reduced; the structure has strong corrosion resistance in offshore environments and low maintenance costs throughout the life cycle;

 

 

Urban Rail Transit Sound Barrier:

The structure’s deadweight is expected to be reduced by 40-50%, with convenient construction and low carbon emissions; the structure has low vibration and reduces secondary noise; the structure has strong corrosion resistance in outdoor environments and low maintenance costs throughout the life cycle;

 

 

Photovoltaic Frame and Bracket:

The mechanical properties are higher than those of traditional aluminum alloy materials; they have strong resistance to salt spray and chemical corrosion; they have good electrical insulation, which reduces the possibility of forming leakage circuits and improves the power generation efficiency of solar panels;

 

 

Photovoltaic Carport:

The structure is highly corrosion-resistant in outdoor environments and has low maintenance costs; the structure is light in weight and easy to install; it has good electrical insulation, which reduces the possibility of forming a leakage circuit and improves the power generation efficiency of the solar panels

 

 

Container House:

The weight is greatly reduced compared to metal structure; inorganic non-metallic materials, good thermal insulation; good corrosion resistance and frost resistance; excellent earthquake resistance and wind resistance under equal stiffness design.
