Pultrusion of composite materials: performance, efficiency, and innovation with DeatexGroup Technical Fabrics

Pultrusion is a continuous manufacturing process used to produce fibre-reinforced composite profiles, typically using glass fibres impregnated with thermosetting resins. This technology makes it possible to manufacture products with high mechanical performance and consistent quality throughout the production process.

Compared with traditional materials such as steel, aluminium or wood, pultruded profiles offer numerous advantages:

• Low weight
• Excellent mechanical strength
• High corrosion resistance
• Long-term dimensional stability
• Reduced maintenance requirements
• Durability even in particularly harsh environments

These characteristics make Pultrusion an increasingly popular solution across a wide range of industrial sectors.

Main application markets

Composite products manufactured through Pultrusion are used across a wide range of markets thanks to their versatility and performance.

Automotive
Structural and semi-structural components requiring low weight, strength and reduced energy consumption.

Construction
Profiles for windows and doors, reinforcement systems, façades, architectural elements and components designed to improve the energy efficiency of buildings.

Wind energy
Structural elements and technical components for wind energy systems, where low weight and resistance to weathering are essential requirements.

Marine
Applications requiring high corrosion resistance and long-lasting performance in marine environments.

Industrial
Ladders, walkways, structural profiles, handling systems and a wide range of technical applications intended for environments subject to high mechanical and chemical stresses.

The added value of Technical Fabrics in Pultrusion

The use of Technical Fabrics in the Pultrusion process is now a key differentiating factor in improving both final product performance and production efficiency.

Thanks to specific formulations and textile constructions, Technical Fabrics help improve the surface quality of the finished product while adding functionalities that are increasingly in demand in the market.

The main benefits of using Technical Fabrics include:

• Improved surface finish of the pultruded profile.
• Natural UV protection and improved long-term appearance.
• Reduced surfacing and protrusion of glass fibre filaments on the finished product.
• Technical Fabrics available in specific Pantone colours.
• Micro-perforated Technical Fabrics to optimise resin impregnation and distribution.
• Flame-retardant or fire-resistant Technical Fabrics according to applicable regulations.
• Printed Technical Fabrics for decorative and customised surfaces.
• Improved final appearance of the component while maintaining high technical performance.
• Greater design flexibility to meet the requirements of different application sectors.

Integrating Technical Fabrics into the manufacturing process therefore makes it possible to combine performance, functionality and aesthetics in a single solution.
