How fiber prevent cracks in coating?
Best insight from top research papers
Fibers play a crucial role in preventing cracks in coatings by deflecting cracks and promoting debonding at the fiber/matrix interface. Various studies have shown that fiber-reinforced coatings exhibit enhanced toughness and resistance to cracking. The incorporation of fibers, whether in multiple unbonded layers or as a single porous layer, helps in toughening composites and resisting oxidation. Fibrous components added to coatings improve high-temperature endurance, thermal shock resistance, and cracking prevention. In the case of thermal barrier coatings, the addition of yttria-stabilized zirconia fibers enhances durability by mechanisms such as fiber breakage, fiber-matrix interface debonding, and crack deflection. Overall, fibers act as reinforcement elements that enhance the mechanical properties and durability of coatings, effectively preventing cracks.

How can scar formation be prevented or reduced?5 answersScar formation can be prevented or reduced through various methods. Early interventions to accelerate wound closure can reduce the over-activation of myofibroblasts and prevent scar development. Rational tactics for dealing with pathological scars include therapeutic, physiotherapeutic, radiological, surgical, and cosmetic methods. Modulation of the wound microenvironment using cerium oxide nanoparticles as an enzyme-like ROS scavenger and pirfenidone as an anti-fibrotic drug can overcome the problems of increased levels of reactive oxygen species (ROS) and high expression levels of transforming growth factor-β (TGF-β) in wound tissue. Topical treatments such as silicone gels containing natural herbal ingredients have shown improvement in scar appearance. The use of an advanced textured electrospun dressing loaded with a natural antifibrotic agent has also been proposed as a suitable solution for hypertrophic scar formation in complex wounds. These methods provide potential strategies for preventing or reducing scar formation.
Can improving stability of encapsulants result in reducing permeability or diffusivity of matrices by using fillers or coatings?4 answersImproving the stability of encapsulants can result in reducing the permeability or diffusivity of matrices by using fillers or coatings. For example, in the context of surface treatment compositions, a transparent flexible coating film with excellent gas barrier properties can be achieved by using a silane compound component and a compound with functional groups capable of reacting with an amino group. In the case of dispersions, the stability of the dispersion can be improved by using a polymeric dispersant with cross-linking groups that form an encapsulation network, which entraps the particles and enhances stability. Additionally, in the context of composite materials, the reinforcement effect of nano and micro scale fillers, as well as dual scale filler reinforcement, can lead to improved tensile strength and barrier properties, reducing permeability and diffusivity. Furthermore, in the context of concrete, minimizing the permeability of the interfacial transition zone (ITZ) through the use of supplementary cementing materials can contribute to reducing the overall permeability of the concrete.
