Electric Injera baking Pan are prevalent in Ethiopia but are highly inefficient, resulting in significant heat loss, high energy consumption, and increased energy bills. This research investigates improving these devices using steel powder as an additive and gypsum as an insulator. The study examines thermal conductivity, baking time, energy consum...
The use of natural fibers (NFs) in polymer composites is a modern trend aimed at developing materials with numerous benefits, including low cost, environmental friendliness, biodegradability, and high specific mechanical performance. Ethiopia is abundant in NFs such as palm trees, sisal, water hyacinth, and the newly emerging water lilies. In areas...
Textile fabric wastes are the second most polluting materials in the world after plastic. This study investigated the thermal
and free vibrational properties of the sandwich composites prepared from recycled fabric materials. Grey cotton fabric(C)
and wool garment waste (G) reinforced a polyester matrix in a different layer arrangement (CCCC, CGCG,...
Materials are one of the basic elements or needs for continuing human beings’ life living and they are used for structural and nonstructural, biomedical, thermal, or other applications. In many types of materials, Composite materials are used in different sectors. The increasing need for eco-friendly, low-density, and lightweight product production...
The purpose of this overview is to discover materials commonly used in the automotive industry and provide an overview of optimized composites to reduce weight, cost, fuel consumption ,and CO2 emissions. The cost of carbon fiber, Al, and Mg lightweight composites is much higher than conventional materials. It is therefore important for research and...

Ethiopia has abundant invasive aquatic plants like water hyacinth and water lily. Large masses of these invasive plants have a negative impact on the country's water bodies, specifically at Lake Tana in Ethiopia, by infesting and deteriorating water quality and reducing the quantity of water. In this research work, an attempt was made to fabricate...
Hybrid Natural fiber composite material is made from two or more natural fibers to achieve better mechanical properties than single fiber composites. In Ethiopian large amount of unused natural fibers resources including palm, sisal and others are available. These can replace synthetic fiber composite materials. Carry out research to change the nat...
