Abstract
Mycelium materials represent a new class of environmentally friendly materials for structural applications that can grow on low-cost organic waste while achieving satisfactory thermal or acoustic insulation properties. The aim of this study is to grow a biocomposite of mycelium on flax tows and then use it as a reinforcement with a geopolymer matrix. To achieve this, three species of mycelium were selected, a culture process was carried out, and then samples of the composite were synthesized with a geopolymer matrix. To determine the utility in terms of structural applications, the density, compressive strength, and thermal conductivity of the samples were tested. Scanning electron microscope images were also taken to observe the microstructure. The results indicate that it is possible to produce a mycelium composite with a geopolymer matrix. A lower density was achieved for all samples than for the geopolymer without reinforcement. The coefficient of thermal conductivity was reduced only for the sample with one of the mycelia. The compressive strength for biocomposites was between 12.1 MPa–14.2 MPa, this value is enough for some engineering applications.
期刊介绍:
Materialwissenschaft und Werkstofftechnik provides fundamental and practical information for those concerned with materials development, manufacture, and testing.
Both technical and economic aspects are taken into consideration in order to facilitate choice of the material that best suits the purpose at hand. Review articles summarize new developments and offer fresh insight into the various aspects of the discipline.
Recent results regarding material selection, use and testing are described in original articles, which also deal with failure treatment and investigation. Abstracts of new publications from other journals as well as lectures presented at meetings and reports about forthcoming events round off the journal.
