Sustainable Materials with Potential Application as Core Materials in Vacuum Insulations

摘要

The paper focuses on the various uses of several types of textile fibers (mainly byproducts) in the development of modern insulation materials with a high value added. These materials bear several specific advantages over conventional insulations, which enable, among others, easier installation. Some of the newly developed insulations can also be used as core insulations in the manufacture of vacuum insulation panels (VIP). In the context of the research, the study of behavior of thermal insulating materials based on organic polymeric and natural fibers (including fibers from recycled textiles) was conducted. The experimental materials were used to study their physical and mechanical properties and their behavior under reduced pressure (up to vacuum) to evaluation their possible use in the field of VIP as core insulations. Researches have shown that developed insulation based on alternative base can have very good potential in the VIP area and compete with the standard core insulations based on glass fibers of SiO_2.
