Research on Fiber Orientation Optimization Strategy and Performance Enhancement of Double-Curved UHPC Shaping

Fiber Orientation Optimization: Injecting the Soul of Performance into Double-Curved UHPC Shapes

Under the dual pursuit of contemporary architectural aesthetics and structural performance, double-curved UHPC (ultra-high performance concrete) shapes have become the "design favorite" of high-end projects such as landmark buildings and cultural venues thanks to their unique spatial expressiveness. However, the complexity of double-curved forms places extremely high demands on material performance. As the core factor affecting the mechanical properties of UHPC, fiber orientation and its optimization strategy directly determine the load-bearing capacity and durability of components. As an industry leader with 28 years of deep expertise in the UHPC/GRC/GRG/GRP materials field, Qinglong Group has accumulated rich practical experience in fiber orientation optimization and performance improvement for double-curved UHPC shapes through full-chain technical accumulation.

Fiber Orientation Challenges and Optimization Paths for Double-Curved UHPC Shapes

The curvature variation and irregular structures of double-curved components cause problems in traditional casting processes such as uneven fiber distribution and disordered orientation, directly weakening the material's tensile strength and toughness. Based on BIM parametric simulation during the detailed design stage, Qinglong Group predicts fiber movement trajectories through three-dimensional flow field analysis, combined with its self-developed "centrifugal-vibration composite molding process," achieving directional alignment of fibers in the key stress zones of curved surfaces. For example, in the translucent concrete project of the Nanjing East Road Century Plaza renovation project, by adjusting mold inclination and vibration frequency, the fiber orientation rate along the main stress direction of the curved surface was increased by 30%, and flexural strength exceeded 20MPa, successfully meeting the structural requirements of large-span double-curved shapes.

Full-Chain Technical Support for Material Performance Improvement

Fiber orientation optimization is not an isolated step; it needs to form a closed loop with material formulation, production processes, and construction installation. Relying on its provincial-level R&D center and 58 patented technologies, Qinglong Group has built a "material-structure-process" collaborative innovation system: on the material side, a composite ratio of basalt fiber and steel fiber is adopted to enhance the interfacial bonding strength between fiber and matrix; on the production side, industrial robots are introduced for precise material placement, combined with microwave curing technology to shorten the molding cycle; on the installation side, 3D laser scanning achieves "zero-error" assembly of components. This full-chain advantage enabled Qinglong UHPC products to reduce material waste by 15% compared to traditional processes in a double-curved curtain wall project for a grand theater in Guangzhou, while improving crack resistance by 25%.

Performance Verification and Value Release in Industry Practice

As a participating drafting organization of the industry standard "General Technical Conditions for Ultra-High Performance Concrete (UHPC) Non-Load-Bearing Components," Qinglong Group has applied fiber orientation optimization technology to numerous major projects at home and abroad. From the double-curved sunshades of a commercial complex in Malaysia to the irregular relief walls of a domestic museum, refined control of fiber orientation has not only enabled the accurate realization of design shapes but also extended the service life of components to over 50 years. This dual guarantee of "aesthetics and performance" is precisely Qinglong's core competitiveness as a UHPC/GRC/GRG/GRP custom manufacturer, providing designers and owners with a full-cycle solution from creative conception to engineering implementation.

Fiber orientation optimization for double-curved UHPC shapes represents a deep integration of materials science and engineering technology. With 28 years of full-chain experience as its foundation, Qinglong Group breaks through the performance bottlenecks of complex shapes through technological innovation, not only pushing the application boundaries of UHPC materials but also injecting more possibilities into the construction industry with its mission of "creating beautiful architecture." In the future, with the development of digital construction technology, fiber orientation optimization will become the key engine for double-curved UHPC shapes to achieve "lightweight, high-strength, and durable" goals, and Qinglong will continue to lead industry innovation with professional strength, contributing Chinese solutions to global architectural aesthetics.
