Agro-composite materials were produced from flax shaves and the properties of these composites were determined experimentally. The structure and morphology of the composites was determined by scanning electron microscopy (SEM), and their thermal conductivities were determined using the transient plane source method. These properties, as well as mechanical, hydric, and acoustic properties were determined as a function of the structure and size of the flax shaves....
The preparation process of silica aerogels has commonly involved a dangerous supercritical drying step, so work has been done to eliminate this step. This paper discusses the preparation of composite silica aerogels containing silica fibers using a method that excludes the supercritical drying step. The physical and thermal properties of these aerogels were subsequently examined. It was found that the composite aerogels produced by the method presented in the article ...
