In modern architectural and infrastructure reinforcement, material performance directly determines the safety, durability, and cost-effectiveness of projects. Recently, the carbon fiber rigid grid product independently developed by Shenzhen Boyue New Technology Co., Ltd. (BOYUE New Technology) has become an industry focus due to its outstanding mechanical properties and broad engineering adaptability. As a core innovation in fiber-reinforced composite (FRP) technology, this product delivers lightweight, high-strength, and exceptional durability, effectively overcoming the limitations of traditional reinforcement techniques. It provides efficient and reliable solutions for the reinforcement and repair of various infrastructure structures, including bridges, tunnels, and industrial plants.
The carbon fiber rigid grid, a flagship product developed by BOYUE New Technology through years of carbon fiber composite research, combines high-performance 12K carbon fiber as reinforcement with specialized corrosion-resistant resin as matrix. Manufactured via advanced integrated molding technology, it perfectly integrates carbon fiber's ultra-high strength with resin's superior corrosion resistance. Compared to traditional reinforcement materials, this product demonstrates exceptional performance: with a density of approximately 1.80g/cm³ (less than 1/4 of steel's density of 7.85g/cm³),
it adds less than 3% extra weight to existing structures. Its tensile strength standard value reaches ≥3500MPa, and elastic modulus exceeds 210GPa, far surpassing conventional steel and traditional reinforcement materials. This design significantly enhances structural load-bearing capacity while minimizing self-weight burden, making it suitable for various complex load scenarios.
In product specifications and quality control, BOYUE New Technology's carbon fiber rigid grid adopts a dual design philosophy of "standardized mass production + customized adaptation" to comprehensively meet diverse engineering requirements. The standard mass-produced product measures 9.3m in length (with 50mm flash on the outermost side) and 3.3m in width (with 50mm flash on the outermost side), featuring 100mm grid spacing in both longitudinal and transverse directions. Precise cutting can be performed according to actual construction needs (cutting loss should be calculated in advance). For high-load or special-size customized scenarios, grid spacing and single-leg cross-sectional dimensions can be flexibly adjusted to create customized products with superior ultimate tensile strength. The flagship model CFG-3500 features a nominal single-leg area of 10.56mm² and ultimate tensile strength of ≥37kN. Key indicators such as tensile elastic modulus and elongation at break strictly comply with the national standard GB/T36262-2018 "Carbon Fiber Reinforced Composite Materials for Structural Reinforcement". It has passed comprehensive testing and certification by authoritative institutions including the National Building Materials Quality Supervision and Inspection Center, ensuring engineering quality and safety from the source.
Compared to traditional reinforcement techniques like carbon fiber fabric and steel bonding, BOYUE's new-generation carbon fiber rigid grid has achieved multiple core technological breakthroughs, establishing comprehensive competitive advantages. In terms of performance, the product demonstrates exceptional durability across all scenarios, capable of withstanding harsh environments including acid/alkali corrosion, high-salt marine fog, and industrial pollution, with no performance degradation over long-term use. Its designed service life reaches 30-50 years. Additionally, it features outstanding impact resistance and fire resistance. When paired with a specialized cement-based reinforcement layer, a mere 1cm-thick protective layer meets stringent fire safety requirements. For construction, the product ensures reliable joint connections and excellent anchoring performance, with tensile bond strength between fiber composite and concrete substrate exceeding 2.5MPa (occurring through internal material cohesion failure), effectively preventing reinforcement layer delamination. The overlap length is reduced by over 40% compared to traditional materials, and the construction process simplifies to "substrate preparation—grid installation—spraying/manually applying cement-based reinforcement layer—curing," eliminating complex procedures like welding and heavy lifting. This results in construction efficiency improvements exceeding 50% over conventional methods, significantly shortening project timelines and reducing labor costs.
BoYue New Technology's carbon fiber rigid grid has been successfully deployed in numerous major projects worldwide, demonstrating proven effectiveness through real-world applications. In the U.S. market, the Oregon Inlet Bridge—a 1963-built harbor structure—had long suffered from severe corrosion and structural degradation in its concrete components due to prolonged exposure to high-salinity marine fog. 
After reinforcement with this carbon fiber grid, five years of monitoring showed no cracks or deterioration in the reinforced layer, while the structure's load-bearing capacity increased by over 35% compared to pre-reinforcement levels. This achievement perfectly meets the long-term operational requirements of harsh marine environments.
In the domestic market, this product has demonstrated exceptional adaptability and reliability. A Class II highway bridge constructed in 1995 (84.745m total length with 5×16m reinforced concrete hollow slab deck) developed minor cracks at its underside due to increased traffic volume. After reinforcement with this carbon fiber grid, the bridge has safely operated for 12 years without any quality defects, maintaining structural load-bearing capacity to meet current heavy traffic demands. Another large highway bridge (454.80m total length, featuring a 3×100m double-ribbed box arch main bridge and 8×16m precast simply supported slab girder approach bridge) experienced aging issues in its approach bridge deck under prolonged stress. Following grid reinforcement, five years of regular inspections revealed no cracking or deformation, with significantly improved structural stability. Notably, in a Class III bridge retrofitting project, this solution showed marked advantages over traditional steel bonding methods: construction time was reduced by 60%, eliminated corrosion maintenance costs, and structural weight gain was only 1/5 of the bonding approach. The enhanced reinforcement effectiveness makes it a superior choice for aging bridge renovations.
Beyond its core applications in bridge reinforcement, BOYUE New Technology's carbon fiber rigid grid demonstrates versatility across diverse scenarios including tunnel lining reinforcement, 
floating bridge structural strengthening, shaft wall protection, large-scale parking lot pavement reinforcement, and industrial facility equipment foundation consolidation. The product has been successfully implemented in landmark projects such as the Grain Terminal Bridge deck reinforcement in New Orleans, USA, and a domestic underground tunnel lining repair. Capitalizing on its product advantages, BOYUE New Technology provides end-to-end carbon fiber composite solutions encompassing customized production, simulation validation, construction technical guidance, and post-construction monitoring, ensuring efficient project execution.
A BOYUE New Technology executive stated that the development and application of carbon fiber rigid grids represent a significant achievement in implementing the company's philosophy of "technology-driven engineering upgrades." Supported by 24/7 rapid technical support and a comprehensive quality control system, the company not only delivers high-performance products but also addresses core challenges in engineering reinforcement through customized solutions and on-site engineering guidance. Moving forward, the company will continue to focus on composite materials, targeting the core needs of infrastructure reinforcement. By continuously optimizing product performance and expanding application scenarios, it aims to provide safer, more efficient, durable, and cost-effective technical solutions for global engineering projects, leading the structural reinforcement industry toward greener and more sustainable development.
