Fibers: understanding, measuring and controlling complex materials

Fibers, whether they are vegetable (linen, hemp, cotton, jute, etc.), from? (wool, silk), mineral (glass, carbon) or synthetic (polyester, polyamide), play a key role in the structure and performance of materials and formulations.
They bring mechanical resistance, elasticity, absorption, texturing or, specific features to the final products.

At Rheonis, we support you for master the complex behavior of fibers in your industrial processes and your innovations, by combining scientific expertise, advanced measurement tools et Customised support!.

Our services around fibers

Beyond simple measurement, we offer a integrated approach :

• Multi-physical characterization fibers and their assemblies
• Dispersion and integration study fibers in formulations (pastes, powders, gels, polymer matrices, etc.)
• Analysis of fiber-matrix interactions in composites and biomaterials
• Sensory and textural evaluation fibers in cosmetics or food processing
• R&D and industrialization support to optimize your processes and formulations

Measurements carried out on the fibers

We use a wide range of tools to study:

• Mechanical resistance and elasticity isolated or networked fibers
• Structure and orientation (microscopy, texture analysis, imaging)
• Rheological behaviors fibrous formulations (pastes, gels, suspensions)
• Absorption and moisture properties (sorption isotherms)
• Tribology to analyze friction and wear in composite or textile materials
• Surface physical chemistry to understand adhesion and impregnation

Industrial applications of fibers

Fibers are at the heart of many processes and products. We work with manufacturers on:

• Textiles and nonwovens : mastery of resistance, flexibility and durability
• Technical composites : integration of glass, carbon or hemp fibers into polymer matrices to reinforce technical parts
• Cosmetics : incorporation of plant fibers to create innovative textures, stabilize formulations or improve sensoriality
• Food : role of wheat, beet, apple, cocoa fibers, etc. in the texture, stability and nutritional value of products
• Biomaterials : valorization of natural fibers in health, packaging or circular economy applications

Common industrial processes associated with fibers

• Spinning and weaving (textiles, composites)
• Molding and infusion (composite parts)
• Compaction and extrusion (functional fibers, biomaterials)
• Grinding and dispersing (plant fibers in cosmetic or food formulation)
• Impregnation and surface treatments (optimization of fiber-matrix interfaces)

This global understanding allows us toanticipate fiber behavior, make your processes more reliable andaccelerate your innovations in various industrial environments.
