Fiber Orientation Optimization Technology for Double-Curved UHPC Forms: Qinglong UHPC Fiber Orientation Control System

Fiber orientation optimization for double-curved UHPC shapes adopts the comprehensive technology of "oriented fiber placement + vibration control + mold design". Through computational fluid dynamics simulation, the distribution of fibers in the flow field is optimized, achieving a fiber orientation degree of over 75% in the main load-bearing direction. Using a high-pressure spraying process, the fiber aspect ratio is controlled at 60-80 with a volume fraction of 2%-3%, achieving the transition from 3D random orientation to 2D oriented arrangement, with flexural strength increased by 25%-30%.

Specific process parameters: spraying pressure 0.5-0.8 MPa, spraying angle 45°-60°, fiber dispersion uniformity ≥90%. A double-curved curtain wall project, through fiber orientation optimization, achieved curved shapes with a minimum radius of curvature R=300mm, with a fiber orientation degree of 78% in the main load-bearing direction and a flexural strength of 28 MPa, 30% higher than conventional processes. Qinglong UHPC fiber orientation technology significantly enhances the mechanical performance of complex shapes.

Fluid Dynamics Simulation

CFD is used to simulate the trajectories of fibers in the flow field and optimize spraying parameters. The effects of flow velocity and viscosity on fiber orientation are analyzed to predict orientation distribution. Through iterative calculation, the optimal combination of process parameters is determined.

High-Pressure Spraying Process Control

Spraying pressure is precisely controlled at ±0.1 MPa to ensure uniform fiber dispersion. Adjustable nozzle angles accommodate different curved shapes. Segmented control of spraying parameters achieves graded performance.

Mold Design Optimization

Optimized runner design guides fibers to align in oriented patterns. Baffle components are installed to control fiber distribution. Mold surface treatment reduces fiber flow resistance.

Real-Time Monitoring System

Image recognition technology is used to monitor fiber distribution online. Process parameters are adjusted in real time to ensure quality control. A fiber orientation database is established to optimize production processes.

Fiber orientation determines component performance. With Qinglong UHPC precise control, material performance is optimized.
