Research on Fiber Orientation Optimization Strategies and Performance Enhancement of Hyperbolic UHPC Shapes

In the field of contemporary architectural design, double-curved surfaces have become an important design language for landmark buildings thanks to their unique visual impact and spatial expressiveness. However, double-curved structures place extremely high demands on material performance, and traditional building materials often struggle to balance form realization with structural safety. As an industry leader with 28 years of deep expertise in UHPC/GRC/GRG/GRP materials, Qinglong Group leverages its full-chain technical advantages to achieve breakthrough progress in fiber orientation optimization and performance enhancement for double-curved UHPC forms, providing a systematic solution for realizing complex architectural forms.

The performance bottleneck of double-curved UHPC components mainly stems from the anisotropy of fiber distribution. In conventional casting processes, fibers tend to agglomerate or break where surface curvature changes, resulting in localized strength degradation. Through its independently developed "dynamic flow field simulation system," Qinglong's technical team has established a correlation model between fiber orientation and surface curvature, achieving precise control of the material's microstructure. Based on the three-dimensional coordinate data of the double-curved surface, the system adjusts casting pressure, mold rotation speed, and fiber feeding angles in real time, allowing fibers to align in an orderly manner along the principal stress direction. The flexural strength is 37% higher than that of traditional processes, effectively solving the industry-wide problem of cracking in curved components.

In production and manufacturing, Qinglong has innovatively combined BIM technology with robotic laying processes to build an intelligent production line for double-curved UHPC components. By pre-programming fiber orientation through parametric design software, robotic arms complete fiber laying along optimal paths, ensuring that the fiber volume content error per square meter of components is controlled within ±0.5%. The production base in Nanning, Guangxi, with an annual capacity of 600,000 square meters, is equipped with 5-axis linkage machining centers and 3D scanning quality inspection equipment, achieving full-process digital management and control from design to finished products, and providing stable capacity assurance for large double-curved projects.

As a national high-tech enterprise and a contributor to the formulation of multiple industry standards, Qinglong has accumulated extensive engineering experience in double-curved UHPC applications. From the translucent concrete double-curved curtain wall of the Nanjing East Road Century Plaza renovation project, to the special-shaped GRC decorative components of the Dongguan Women and Children's Activity Center, Qinglong has always upheld its mission of "creating beautiful architecture," perfectly integrating material performance with artistic expression. Notably, through fiber orientation optimization technology, Qinglong's double-curved UHPC components weigh 60% less than stone of the same volume, significantly reducing building structural loads and opening up more possibilities for form innovation in super high-rise landmark buildings.

Looking to the future, Qinglong Group will continue to focus on technological innovation in UHPC/GRC/GRG/GRP materials. Guided by the vision of "becoming an outstanding world-leading manufacturing enterprise," it provides designers and owners with full-chain expert services ranging from detailed design to after-sales maintenance. Today, as double-curved architecture becomes increasingly widespread, fiber orientation optimization technology is not only a means of enhancing material performance, but also a core driving force for the coordinated development of architectural aesthetics and engineering safety. With its professional strength, Qinglong is writing a new chapter in the application of new architectural decorative materials. For more industry information: +WeChat qlfsbl123
