Taking from more natural, less energy-intensive resources, Terrene 3.0 explores the enhancement of lightweight, bio-based earthen construction in a wide leg arch by combining structural and material optimization methods. It is composed of ChitoSand \u2014 a thin bilayer of sand augmented with chopped flax fiber, citric acid as a plasticizer and bound by chitosan biopolymer \u2014 and underlaid by a sewn burlap fabric base layer. The fiber reinforcement provides the arch with increased tensile strength, the citric acid stability, and the burlap confers additional bending stability. Together, according to an article submitted on the project, the structure \u201coffers concrete-like strength when employed in a structure and nutrients back to the soil when degraded,\u201d achieving minimal waste during fabrication.<\/p>\n\n\n\n

The Now and Next In Composites<\/h3>\n\n\n\n

The composites industry is constantly being shaped and reshaped by myriad forces – people, markets, technologies – all stimulating innovative new ways to apply fiber-reinforced materials in everything from boats and wind blades to airplanes and automobiles. CW Trending is a monthly video podcast that takes a closer look at these composites forces and helps you make sense of them. CW Trending features subject-matter experts, material suppliers, technology mavens and CW’s own editors to explore the ideas, technologies, trends and innovations in development or already in the marketplace. Join us and be a part of the conversation.<\/p>\n\n\n\n

Future work is underway to enhance water resistance, increase scale and explore other material options to enable a more permanent earthen tension-compression pavilion.<\/p>\n\n\n\n

\u201cAt DumoLab, we use simple materials and ambient conditions manufacturing to assemble structures closer to nature\u2019s way and with properties competitive with other unsustainable practices,\u201d says <\/strong>Dr. Laia Mogas-Soldevila<\/a>, director of DumoLab Research and assistant professor of architecture at the University of Pennsylvania.<\/p>\n\n\n\n

Mogas-Soldevila has also been a part of the Water-Based Digital Fabrication project that CW<\/em> reported on in 2021. The MIT project developed and patented a novel robotic deposition system using water-based solutions<\/a> of bio-polymers like chitin and cellulose to create tailored biocomposite structures.<\/p>\n\n\n\n
