Knowledge and study on the thermal and mechanical performance of the low consumption wall of the building with composite properties and thermal insulation materials

A composite material (also called a composition material or shortened to composite, which is the common name) is a material which is produced from two or more constituent materials. These constituent materials have notably dissimilar chemical or physical properties and are merged to create a material with properties unlike the individual elements. Within the finished structure, the individual elements remain separate and distinct, distinguishing composites from mixtures and solid solutions. There are various reasons where new material can be favoured. Typical examples include materials which are less expensive, lighter, stronger or more durable when compared with common materials, as well as composite materials inspired from animals and natural sources with low carbon footprint. Silkworm cocoons are a natural biological and composite structure that has evolved over time and responds well to the environmental conditions for silkworms. Understanding the relationships of cocoon structure inspires the creation of materials such as low-weight, high-strength non-woven bio composites. In this study, the descriptive-analytical method and logical reasoning, using sericin cocoon and natural fibers, which for various reasons such as lightness, non-pollution, and low-cost, can be a suitable alternative to artificial fibers, offer materials as a non-woven bio composite. These materials are suitable in terms of stability and energy consumption, can be used as thermal insulation. This performance is simulated for the hot and dry climate of Kashan city in the outer shell of the building and using the HanyBee energy analysis plugin in the Grasshopper environment. The results show that the proposed non-woven bio composite can help improve the thermal performance of the building by up to ۱۲.۷%.
