全球 35% 以上的能源以及近 45% 的资源应用于建筑行业中。如果人口持续增长, 2030 年全球将需要比现在多 40% 的能源。为应对需求,我们需要为传统的不可再生资源寻找替代方案。现在大部分能源都被用于传统建筑材料如混凝土或钢铁的生产中。为满足可持续性建筑材料的要求,可以使用天然纤维生物复合材料来代替资源密集型材料(如钢、混凝土等)和其他合成纤维(如碳、玻璃等)。生物复合材料即天然纤维复合材料(NFRP),是由至少 2 种主要组分—纤维和基质(也称为黏合剂)制成的,其中至少有一种是基于生物的组分。天然纤维由于其可回收性和可重复使用性高,可以实现完整的生命周期,同时还具有现代性、几何灵活性和可持续性,这些特性在为实现更高的建设目标而寻求新的制造工艺时显得尤为突出。

生物复合材料展馆是一个高 3.6 m,跨度 9.5 m 的分段式壳体结构,通过真空辅助层压工艺将 121 个经过了参数优化的弯曲元件组合成型。每个元件的核心都以天然材料为基础,由单板形式的长木纤维加固,并涂有抗紫外线树脂以抵抗风化。每个元件的核心都是通过压铸工艺制造而成的柔性板,其混合了生物塑料和天然纤维。天然纤维(例如稻草)这样的农业生产废料,在这里作为建筑材料获得了第二次生命。

生物复合材料研究馆展示了由天然材料制成的新型建筑材料在建筑和结构上的潜力。生物材料项目组专注于研究其在建筑中不同方面的可持续性。这一建成项目是 10 个月高强度工作的成果,也是在生物材料应用领域中长期工作的一部分以及对可持续性建筑未来发展的探索。

 

The building industry is responsible for more than 35% of global energy and almost 45% of global resource. If the population will continue the growing in 2030 the population will need 40% more of energy than today. To meet this demand it is necessary to find alternative solutions to traditional non-renewable resources. Traditional materials such as concrete or steel are responsible for most of the energy consumption. To meet the requirements for sustainable building materials the natural fiber bio-composites can be used instead of resourceintensive materials (steel, concrete etc.) or the other synthetic fibers (Carbon, Glass). Biocomposite materials, i.e. natural fibre reinforced polymeric composites (NFRP), are materials fabricated from at least two main components, a fibre and a matrix (also known as binder), where at least one of the two main components is biomass-based. Thanks to high recyclability and reusability natural fibers can achieve a closed life cycle hand in hand with modernity, geometric flexibility and sustainability, especially when new manufacturing processes are used to achieve higher architectural goals.

The 3.6 m height, 9.5 m span research biocomposite pavilion is an interconnected segmented shell construction consisted of 121 parametrically optimized cur ved elements prepared by a vacuum-assisted veneer-reinforcement lamination process. Natural-based core of each element was reinforced by long wooden-fibres in the form of veneer, then coated with UV-resistant resin to resist against weathering conditions.

BioMat Research Pavilion demonstrates the architectural and structural potential of novel building materials made from natural material. BioMat department focuses on a mission of examining different sustainability aspects in architecture. This built work is the result of 10 months of intensive work, following many years of work in the field of applications of bio-based materials and diverse approaches towards futureoriented sustainable architecture.
