Bally Ribbon Mills (BRM), an industry leader in the design, development, and manufacture of highly specialised engineered woven fabrics, will showcase its high-quality, high-performance products at CAMX 2019, taking place from 23-26 September 2019 in Anaheim, CA. BRM experts will be on hand to discuss the company’s 3D woven joints, thermal protection systems (TPS), and other 3D structures.

BRM uses 3D continuous weaving to create new joint structures and improve existing joints. Delivering the optimal blend of strength, durability, and structural integrity, BRM’s 3D woven joints are available in Pi – π, double T, H, and other complex net shapes. “3D woven joints from BRM lower weight and cost without sacrificing integrity and performance,” the manufacturer explains. “Because of the nature of the 3D weave, strength and support is translated in all three dimensions, thus enabling the join to reinforce the strength along the load paths of the sub-structures being joined together.” These 3D woven shapes for joining can be tailored to suit the architecture of the structure itself, as well as the sub-components being joined.

3D woven composites by BRM are particularly successful in aviation heat shield applications, such as thermal protection systems. These systems are mission-critical components, particularly in space exploration vehicles, and 3D woven composites reduce weight and cost while maintaining performance in TPS systems, the company reports. The ability to vary yarn types, density, thickness, and width, as well as resin type, allows BRM to create fully customisable TPS to fit each specific mission or application’s needs.

Along with TPS systems, 3D woven components are also suitable for engine parts in aircraft. Replacing traditional titanium engine components with 3D woven carbon fibre composites serves to reduce weight and therefore lifetime cost, all while meeting the rigorous demands of manufacturing and use.
