Textile Reinforcement Using Yarn and Method for Preparing a Yarn

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a method for treating yarn, especially multifilament yarns like carbon or AR-glass fibers, to improve their wettability and bonding with matrix materials, particularly mineral-based (such as concrete). The method uses plasma-chemical or plasma-physical processes to modify the yarn surface, making it more hydrophilic and allowing better penetration and bonding with coatings or matrix materials. This plasma treatment facilitates the application of additional functional layers, such as ceramic or metallic coatings, directly to the fibers, enhancing performance without the need for temperature-sensitive polymer coatings.

Use CasesContent extracted from patent full text and abstract with AI.

• Reinforcing concrete structures in construction using advanced textile reinforcements (carbon or glass fiber reinforced concrete).
• Manufacture of high-performance, durable textile-reinforced concrete components for buildings, bridges, and infrastructure.
• Creation of flexible, corrosion-resistant reinforcement meshes or rods that can withstand high temperatures (e.g., fire-resistant structures).
• Production of electrically conductive textiles for heating systems or embedded sensors within concrete structures.
• Application in any composite material where strong, lasting bond between fibers and matrix is essential, especially under harsh environmental conditions.

BenefitsContent extracted from patent full text and abstract with AI.

• Significantly improved bonding between fibers and mineral matrix materials, leading to higher mechanical performance and more efficient use of fiber strength.
• Eliminates the need for polymer coatings, increasing temperature resistance and long-term durability (especially important for fire safety and harsh environments).
• Enables the use of environmentally stable and corrosion-resistant reinforcement materials (e.g., carbon, AR-glass, basalt) in concrete without extensive concrete cover.
• Allows for the addition of ceramic or metallic layers for extra functions, including electrical conductivity for heating elements or sensors.
• The process can be applied industrially (scalable), is cost-effective, and does not require chemical activation or polymeric binders.
• Retains the flexibility and handling benefits of textile reinforcements, as coatings can be localized or applied as needed.

Patent Abstract

Die Erfindung betrifft ein Verfahren zur Vorbereitung eines Garns, insbesondere ein Multifilamentgarn, für einen Einsatz als textile Bewehrung in einem Matrixmaterial, insbesondere einem mineralischen Matrixmaterial, eine textile Bewehrung und ein Bauteil, umfassend diese Bewehrung. Aufgabe der Erfindung ist es, die Benetzbarkeit von Multifilamentgarnen zu verbessern, vor allem für wässrige mineralische Beschichtungen. Zur Lösung wird die Oberfläche des Garns mittels eines plasmachemischen und/oder plasmaphysikalischen Prozesses in der Weise modifiziert wird, dass durch die resultierende Modifikation zumindest die Benetzbarkeit verbessert wird.
