The Role of Textile Materials and Nano Technology for Improving Thermal Insulation in Modern Buildings
Keywords:
Ceramic and nano-crystalline ceramic and composite materials, technical textiles/fibers (glass, basalt,..), content, and it is in fiber glass (E) (54%), and in basalt fiber (65%) By referencAbstract
Nanoscience has invaded contemporary and modern research related to the search for materials whose applications require high-performance
experiments, and the word nano means at first glance dimensions smaller than (100 nm), so the properties of nanomaterials differ from the properties of traditional materials, whether they are composite or from a single source or component. The distribution of mechanical, thermal and chemical stresses at a level of (1 nm) will increase the quality, durability and resistance of the product than it was previously, that is, the interfaces between the phases in the structure will increase, and the final products will become high-performance.
This research represents a distinguished step within the framework of research related to the study of composite and smart materials that are reinforced with nano-particles with porous voids, which are also nano-dimensional / with polymer and with technical textiles such as glass and basalt fibers in particular, with the aim of improving mechanical properties and maintaining thermal properties at the same time, as well. And thanks to the flexibility of the initial preparation stages and the use of techniques such as electrospinning to prepare nanofibers or with a number of special additives and materials that play an effective role in serving the required application in the possibility of thermal insulation of buildings, and in civil engineering applications (reconstruction) and materials science engineering using many techniques, including spray coating.
Five samples had been prepared of composite textile materials reinforced with nanoparticles and closed-cell rigid polyurethane foam, the materials were protected with a layer of epoxy. We used 2D and 3D spacer fabrics and basalt fibers, which have (SiO2) studies, the percentage (7% by weight) was adopted for the amount of nanoparticles and porous structure of silica, as a sufficient and functional percentage and economically, to reduce
the heat transfer coefficient within the range (0.028-0.088 w/m.k), and the thickness also played a major role in thermal insulation, in line with the requirements of the thermal and acoustic insulation products guide of buildingsthermal treatments, thermal insulation in modern buildings
