Use of gel-coat comprising multicomponent laminating, infusion or wrapping epoxy-based resin system and nanoscale hydrophilic metal oxide particles, e.g. as friction- and wear protective layer in fiber reinforced plastic composite cylinders

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

This invention relates to a gel-coat used on fiber reinforced plastic composite cylinders. The gel-coat is made from a special epoxy resin system combined with nanoscale hydrophilic metal oxide particles (such as silicon dioxide, aluminum oxide, or titanium dioxide). This coating provides the cylinder surfaces with enhanced properties, including reduced friction, greater wear resistance, and increased ductility.

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

• Protective coating for hydraulic or pneumatic cylinders made from fiber reinforced plastic composites
• Wear-resistant liners in industrial machinery
• Low-friction surfaces in moving components of engineering systems
• Medical devices using composite cylinder components requiring durable, low-friction surfaces
• Transport equipment such as roller or bearing sleeves needing long-lasting protection

BenefitsContent extracted from patent full text and abstract with AI.

• Significantly reduces friction between the cylinder and other moving parts, improving efficiency
• Enhances wear resistance, extending the service life of composite cylinders
• Provides a ductile, less brittle surface layer, making the cylinders less prone to cracking or breaking
• Supports diverse applications by enabling the use of lightweight, strong composite materials in harsh environments
• Can reduce maintenance needs and costs due to improved durability

Patent Abstract

Use of a gel-coat comprising a multicomponent laminating-, infusion- or wrapping epoxy-based resin system and nanoscale hydrophilic metal oxide particles made of silicon dioxide, aluminum oxide, titanium dioxide, or a combination of hydrophilic silicon dioxide, aluminum oxide or titanium dioxide and hydrophobic silicon dioxide, as friction- and wear protective layer in fiber reinforced plastic composite cylinders (1) for providing a low-friction, wear-resistant and ductile cylinder surface, is claimed. An independent claim is also included for the fiber reinforced plastic composite cylinder comprising the low-friction, wear-resistant and ductile cylinder surface exhibiting the above gel-coat.
