| description | Considering the current environmental problems that has been generated by the excessive production of synthetic plastics, more sustainable alternatives have been proposed. One of these recently studied materials are the mycelium composites, a product obtained with lignocellulosic particles agglomerated together by the myceliar growth of a filamentous fungus. This novel type of materials could represent an option to replace non-biodegradable materials. In this work, mycelium composites with characteristics comparable to expanded polystyrene (EPS) and potentially suitable for fabrication of insulation panels were developed using a Lentinus crinitus strain previously selected after mycelial phases tests. Mechanical variables in bending, compression strength and stiffness were measured following ASTM D143 standard. Two protocols for composite fabrication were followed using different compression loads. Flexural strength reached 0.48 MPa and compression strength 0.235 MPa. Results obtained were compared with data of balsa wood (Ochroma pyramidale) for the similarity of possible applications, expanded polystyrene as its possible substitute and early published data on mycelium composites. Mechanical performance in flexural and compressive strength of the obtained materials revealed their potential use as biodegradable alternatives to some applications of synthetic plastics as insulation panels and packing materials. |

Considerando la problemática actual que ha generado la producción desmedida de materiales plásticos sintetizados de hidrocarburos, se ha buscado desarrollar alternativas más sustentables. Un material alternativo que se ha estudiado recientemente, son los composites (o compuestos) miceliares, productos obtenidos de la cohesión de partículas de desechos lignocelulósicos por medio del crecimiento de una matriz miceliar de un hongo filamentoso. Dichos productos pueden presentar potencial para suplir a materiales no biodegradables. En el presente trabajo, se desarrollaron composites miceliares con características comparables al poliestireno expandido y adecuados para la fabricación de paneles aislantes, utilizando una cepa de Lentinus crinitus, la cual fue puesta a prueba previamente para determinar su utilidad para ese fin. Variables mecpanicas como la resistencia a la compresión y rigidez fueron medidas siguiendo la norma ASTM D143. Para evaluar la importancia que puede representar el prensado de los composites en su fabricación, dos protocolos fueron seguidos, utilizando dos diferentes cargas de prensado como parte del proceso de obtención del producto final. La resistencia a la flexión de los materiales puestos a prueba alcanzó 0.48 MPa y la resistencia a la compresión 0.235 MPa. Los resultados se compararon con los obtenidos en madera balsa, por considerarse un producto natural con características semejantes en cuanto a sus aplicaciones; poliestireno expandido, como su posible sucedáneo; y datos recabados de publicaciones previas sobre composites miceliares. El comportamiento mecánico de los materiales obtenidos en este estudio ante cargas de flexión y de compresión demuestra que estos tienen viabilidad como alternativas a algunos plásticos sintéticos utilizados en aplicaciones como los paneles aislantes y materiales de embalaje.
