Stringer Reinforces Aero-structure Tooling in One-Shot RTM Technolgy

One-Shot RTM for Stringer-Reinforced Aerospace Structures

Efficient production technologies are key to meeting the future demands of the aerospace industry. Our innovation focuses on the one-shot resin transfer molding (RTM) process for manufacturing stringer-reinforced thermoset composite parts. By combining skin and stiffener elements in a single manufacturing step, the process eliminates the need for secondary bonding, reduces cycle times, and ensures outstanding structural performance.

The developed tooling concept is designed for future serial production, supporting scalability while maintaining high precision and reproducibility. Advanced temperature and pressure control enable optimized resin flow and curing, ensuring void-free laminates and excellent fiber-matrix adhesion.

The innovation addresses critical challenges in aerospace manufacturing:

Weight reduction through optimized composite design

Cost efficiency by reducing process steps and material waste

High structural integrity with superior load-bearing capabilities

Industrial scalability for next-generation aircraft programs

This approach represents a significant step towards more sustainable and economically viable aerospace production. By integrating one-shot RTM technology with stringer-reinforced designs, we demonstrate how innovation in materials and processes can support the transition from prototypes to efficient serial production.

Our contribution showcases the potential of advanced composite manufacturing to deliver lighter, stronger, and more cost-effective solutions for the aerospace industry of tomorrow.
