“…This allowed the folded legs to be connected on the inside to form a closed and thus stronger cross-section. In contrast to the Tailored biocomposite mockup that was developed by BioMat [ 26 ] and “Tailoring Self-Formation” [ 25 ], the folding creates not only two-dimensional surface structures but also structural depth for a sturdier self-supporting structure.…”

Fiber Reinforced Polymers (FRPs) are increasingly popular building materials, mainly because of their high strength to weight ratio. Despite these beneficial properties, these composites are often fabricated in standardized mass production. This research aims to eliminate costly molds in order to simplify the fabrication and allow for a higher degree of customization. Complex three-dimensional shapes were instead achieved by a flat reinforcement, which was resin infused and curved folded into a spatial object before hardening. Structural stability was gained through geometries with closed cross-sections. To enable this, the resource-saving additive fabrication technique of tailored fiber placement (TFP) was chosen. This method allowed for precise fibers’ deposition, making a programmed anisotropic behavior of the material possible. Principles regarding the fiber placement were transferred from a biological role-model. Five functional stools were produced as demonstrators to prove the functionality and advantages of the explained system. Partially bio-based materials were applied to fabricate the stool models of natural fiber-reinforced polymer composites (NFRP). A parametric design tool for the global design and fiber layout generation was developed. As a result, varieties of customized components can be produced without increasing the design and manufacturing effort.

“…The Tailored biocomposite mock-up ( Figure 1 a) developed by BioMat at ITKE/University of Stuttgart is a generatively designed single curved canopy structure, optimized in order to minimize the material usage [ 26 ]. Multiple designs were analyzed and the one with the lowest deformation was chosen.…”

“…To exemplify this approach and the way that IT and sustainability are integrated in this context, the Tailored Biocomposite Mockup of 2019 was created [42,43]. It was planned that the additive manufacturing technology, known as Tailored Fiber Placement (TFP), would be used to create the double-curved building element.…”

This article aims at addressing the future challenges in Sustainability and Information Technology (IT) by reversing the order of the conventional prioritization of social objectives and technology, and placing the aim first and the means second. In engineering and technology, historically, there has been greater focus on first developing the technologies (means) and then determining their potential (aim), and how to tame their unintended consequences. The greatest challenge confronting humanity in the coming decades is sustainability. Therefore, the question is how can IT design, develop, and assist in maintaining the ambitious, albeit difficult to grasp, sustainability agenda? This discussion is pertinent in order to avoid research programs and academic curriculum which dive into the intricacies of IT without viewing sustainability as a core value, which ultimately risks replicating the historical pattern that will generate even more unsustainability.

“…In previous research work by the author [7,13], straw was filled in a modified thermoplastic lignin instead of the cellulose fibres, and the properties’ differences between the two green lignin biocomposites were analysed, especially for the fire-resistance behavior. The result has shown a large improvement due to the application of raw rice straw that is naturally filled with silica, causing a change in the material class of the straw–lignin biocomposite.…”

Due to the high amounts of waste generated from the building industry field, it has become essential to search for renewable building materials to be applied in wider and more innovative methods in architecture. One of the materials with the highest potential in this area is natural fibre-reinforced polymers (NFRP), which are also called biocomposites, and are filled or reinforced with annually renewable lignocellulosic fibres. This would permit variable closed material cycles’ scenarios and should decrease the amounts of waste generated in the building industry. Throughout this paper, this discussion will be illustrated through a number of developments and 1:1 mockups fabricated from newly developed lignocellulosic-based biocomposites from both bio-based and non-bio-based thermoplastic and thermoset polymers. Recyclability, closed materials cycles, and design variations with diverse digital fabrication technologies will be discussed in each case. The mock-ups’ concepts, materials’ compositions, and fabrication methods are illustrated. In the first case study, a structural segmented shell construction is developed and constructed. In the second case study, acoustic panels were developed. The final case studies are two types of furniture, where each is developed from a different lignocellulosic-based biocomposite. All of the presented case studies show diverse architectural design possibilities, structural abilities, and physical building characteristics.
