Research on Texture Implementation Methods and Craft Techniques for Bionic GRC Shapes

In the field of contemporary architectural design, the fusion of bionic aesthetics and material technology is becoming key to shaping distinctive spatial character. As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, Qinglong Group deeply understands the core value of texture in bionic GRC shaping—it is not only a carrier of visual art, but also a concentrated embodiment of material performance and process wisdom. This article systematically analyzes the texture realization methods and process techniques of bionic GRC shaping, from texture design logic and process implementation paths to quality control systems, providing designers and owners with professional solutions that combine aesthetic value with engineering feasibility.

I. Design Logic of Bionic GRC Texture: Translating Natural Forms into Engineering Language

Realizing texture in bionic GRC shaping first requires establishing a three-stage design logic of “natural texture—digital modeling—material adaptation.” In the Dongguan Women and Children's Activity Center project, the Qinglong team drew inspiration from leaf vein structures, converting natural textures into quantifiable engineering data through Rhino parametric modeling, then optimizing texture depth and density based on GRC material characteristics. This design method preserves the organic beauty of biological textures while ensuring the structural stability of components—for example, controlling the groove depth of bionic textures within a 5-15mm range satisfies visual expressiveness while avoiding cracking risks caused by stress concentration.

For complex curved surfaces, Qinglong combines BIM technology with 3D scanning to achieve precise texture mapping. In the Nanjing East Road Century Plaza translucent concrete project, natural stone texture data was imported into the BIM model to achieve a 1:1 replication of natural textures on GRC component surfaces, while leveraging the light-transmitting properties of GRP materials to present the dynamic bionic beauty of textures under changing light and shadow. This cross-material collaborative design is a typical example of Qinglong's innovation in material applications as a national-level high-tech enterprise.

II. Core Process Techniques: Breakthroughs in Mold and Forming Technology

Molding technology is the core link determining the precision of bionic GRC textures. Qinglong's “multi-stage mold reproduction technology” solves the problem that traditional molds cannot precisely replicate complex textures: first, a master mold is made of silicone to fully capture the detail features of the original texture; then a working mold is reproduced with fiberglass (GRP) to ensure the mold has sufficient strength and durability; for ultra-fine textures (such as bionic scales and bark cracks), 3D printing mold technology is innovatively introduced to achieve 0.1mm-level texture precision control. This process combination was verified in a theme park project in Malaysia, successfully achieving texture consistency across nearly a thousand special-shaped GRC components.

In the material forming stage, Qinglong's original “directional fiber laying process” significantly enhances texture expressiveness. By computer-controlling the laying angle and density of glass fibers so that the fiber orientation aligns with the stress direction of the bionic texture, it both strengthens the mechanical performance of components (bending strength above 20MPa) and gives the texture rich layers at different lighting angles. Combined with precise spray-up forming technology, the concrete slurry is evenly applied over the mold surface, ensuring texture depth error is controlled within ±0.5mm—a process standard that has reached the highest grade requirements of the International Glassfibre Reinforced Concrete Association (GRCA).

III. Quality Control and Full Lifecycle Management

Ensuring the durability of bionic GRC textures requires a full-process quality control system. Qinglong has established a “three-level quality control standard” covering everything from raw material inspection to finished product installation: at the raw material stage, low-alkali cement and alkali-resistant glass fibers are strictly selected to ensure no alkali efflorescence on texture surfaces for 20 years; in production, RFID chip implantation technology enables production data traceability for each component; in the installation stage, 3D laser scanning positioning ensures texture jointing errors do not exceed 2mm. This systematic quality control ensured that in the Guangzhou convention and exhibition center project undertaken by Qinglong, nearly 10,000 square meters of bionic GRC curtain wall remained intact in texture over 5 years of use, with no cracking or fading.

As a vice president unit of the China GRC Association, Qinglong has always combined process innovation with industry standard development. When participating in formulating the Technical Standard for Building Applications of Glassfibre Reinforced Cement (GRC) (JGJ/T423-2018), Qinglong specifically incorporated process parameters for bionic textures into the specification, driving industry technology upgrades. Meanwhile, by establishing an after-sales maintenance network covering the whole country, Qinglong provides customers with long-term services such as texture restoration and surface protection, truly achieving full lifecycle assurance from design to maintenance.

From imitating nature to transcending nature, realizing texture in bionic GRC shaping is a perfect fusion of materials science, digital technology, and craftsmanship. With 28 years of technical accumulation, Qinglong Group transforms every texture into the unique language of architecture, not only endowing landmark buildings with vivid vitality but also setting a quality benchmark of “creating aesthetic architecture” for the industry. In the future, with continuous breakthroughs in UHPC, GRG and other material technologies, Qinglong will continue to explore more possibilities of texture expression, allowing architectural art and engineering technology to achieve a higher-dimensional unity in bionic aesthetics.
