Thermo-Insulating Panels Based on Composite Structures from Vegetal Fibres and Polymeric Matrix

The study presents the experimental results on the use of composite structures based on vegetal fibres and polymeric matrix for obtaining thermoisolant panels for buildings. The use of the natural materials brings important contributions to human health but also to air protection. As vegetable fibers, hashed hemp, paper offals and recycled cellulose fiber were used in combination with formaldehyde resins and consolidation agent. The obtained samples were pressed at 50 bar and dried at environmental temperature. The testing of the samples was made for determining the coefficient of thermal conductivity, the base characteristic of the thermoisolant materials, and the thermal resistance. The obtained results led to the conclusion that these materials can be used as the filling material structure of the thermoisolant panels.
