In the construction industry, fiberglass mesh is widely used for wall reinforcement, external wall insulation systems, internal wall insulation, interior wall moisture and fireproofing, roof waterproofing, crack resistance, reinforcement of cement products, and as a backing material for granite, mosaic, and marble due to its high strength, alkali resistance, and acid resistance. In insulation systems, it can evenly distribute stress, preventing cracks and acting as a "soft reinforcing steel." In composite wall insulation systems, using a 5-10mm mesh size can disperse the shrinkage stress of the plaster mortar, reducing the probability of surface cracking by up to 76%. During external wall insulation construction, the 160g/㎡ specification product can withstand an impact strength of 12kN/m², meeting the requirements of JG158-2004 standard. The T/CFIA P1-2022 standard, implemented in 2022, specifies that products used for interior walls must pass a 28-day alkali resistance test, with warp and weft tensile strengths of not less than 1250N/50mm and 1050N/50mm, respectively. Inferior products, due to insufficient zirconium oxide content (<14.5%), are prone to cracking and peeling of the protective layer.
In 2024, the Tianzhou cargo spacecraft adopted a fiberglass mesh solar panel substrate for the first time. This fiberglass mesh structure has advantages such as lightweight, stronger protection against atomic oxygen and plasma, oxidation resistance, and light weight, and can achieve bi-sided power generation. Professor Chen Nanliang's team at Donghua University developed a special warp knitting machine and weaving process for this purpose. Through a twisting process, brittle fibers with a single filament diameter of 7μm are twisted into composite yarns with a tensile strength of 2200MPa. The mesh structure reduces the substrate weight by 34% while maintaining a radial tensile strength of 26kN/m. The silicone resin coating after weaving ensures a surface flatness error of ≤0.05mm, and improves the high and low temperature cycling performance (150℃ to -180℃) to three times that of traditional aluminum alloy substrates. This structural design increases the solar cell installation efficiency by 40%.
Fiberglass mesh is also used in machinery manufacturing (such as abrasive wheel mesh), chemical industry (such as filter materials), road engineering reinforcement, underfloor heating system installation, shipbuilding, automotive industry, sports facilities, agricultural greenhouses and other fields.
