The ability of a drone inlet to withstand high-speed airflow without deformation, or an aero-engine casing to maintain structural integrity under extreme temperatures—these performances increasingly rely on textile composites. In July 2026, a major project titled 'Key Technologies and Applications of Multi-Level Design and Manufacturing for Aerospace Textile Composite Structures' passed expert appraisal organized by the China National Textile and Apparel Council. The project was jointly completed by Northwestern Polytechnical University, Yunlu Composite Materials (Shanghai) Co., Ltd., Chengdu Aircraft Industry (Group) Co., Ltd., Donghua University, and Chengdu Zongheng Dapeng UAV Technology Co., Ltd. The overall technology was rated as internationally advanced.
Core Technology: Full-Chain Breakthrough from Fiber to Structure
Textile composites offer high specific strength, high specific stiffness, fatigue resistance, and impact resistance. However, their complexity—multi-scale, multi-component, and complex fabric architecture—makes mechanical response and damage failure mechanisms difficult to control precisely. The project team addressed this pain point by building a full-chain technical system covering material characterization, multi-scale modeling, structural design, and high-performance manufacturing.
Three core innovations form the foundation. First, a multi-scale predictive analytical model for progressive failure behavior of aerospace textile composites was established, forming a wide-strain-rate mechanical property characterization and simulation methodology. This allows engineers to predict failure modes at different strain rates before actual application, significantly reducing testing costs. Second, a multi-level performance design and evaluation method for textile composite structures was developed, enabling precise prediction and evaluation of key mechanical properties for full-scale aerospace composite structures. Performance at every level—from micro-fiber to macro-component—can be quantitatively controlled. Third, a high-performance manufacturing and conformity verification method for aerospace textile composite structures was established, along with an integrated platform covering design, collaborative weaving, online inspection, and VARI (Vacuum Assisted Resin Infusion) molding. This platform streamlines the entire process from design to final product, ensuring every component meets aerospace-grade standards.
Industrial Application: The Critical Leap from Lab to Production Line
Currently, the project has established flexible manufacturing production lines for complex aerospace structures using textile composites. This means the technology has moved beyond papers or prototypes to batch production capability. Related products have been applied in drone inlets, aero-engine casings, and containment rings, delivering significant economic and social benefits.
For the textile industry, this application carries dual significance. On one hand, it proves that textile composites can enter the aerospace sector, which demands the highest safety standards, breaking the traditional ceiling for textile applications. On the other hand, it drives the overall upgrade of upstream 3D weaving intelligent equipment, high-performance fiber products, and downstream aerospace manufacturing processes. Yunlu Composite Materials, as the developer of 3D weaving equipment, supports product consistency from the equipment side; Chengdu Aircraft Industry, as a leading aerospace manufacturer, provides engineering validation and mass production demand; Donghua University offers fundamental theoretical support in fiber assembly design. This 'university + equipment maker + OEM' collaboration model provides a replicable path for other high-end composite material projects.
Implications for the Supply Chain: Who Benefits, Who Catches Up
From the perspective of buyers, the localization of aerospace composite components means enhanced supply chain security and cost control. High-performance prepregs and structural parts that previously relied on imports now have a domestic technology pathway. For upstream fiber producers, demand for aerospace-grade carbon fiber, glass fiber, and specialty fabrics will grow as the technology spreads, but entry barriers will also rise significantly—suppliers must not only meet mechanical performance targets but also pass multi-level verification system assessments.
For textile machinery companies, 3D weaving, online inspection, and VARI equipment will face new market opportunities. Currently, few domestic companies can produce aerospace-grade 3D weaving equipment. Once technical barriers are broken, those who establish production capacity first will gain a first-mover advantage.
