Netherlands set up bio-Bridge: made from hemp and flax fiber-IT information
In order to find a more sustainable than traditional building materials, building materials, from four Netherlands University students build a length of 14 meters, pedestrian-only bridge from Tai. made from hemp and flax fibers. This so-called "bio-bridge" is located in the Netherlands PSV Eindhoven, will open to the public.
This project began in January and June building bridge models, beginning in August the last stages of construction until last week to complete.
Hemp and flax fibers are embedded in the polylactic acid foam core sandwich, and then to fill in bio-resin, it will harden and together with fiber, final synthesis of composite materials. Some building materials such as steel, concrete, or be more substantial than the bio-composite material of carbon fiber, but good material abundance and the environment is far less. Characteristics of the material has low density, biodegradable and compostable.
Even though it has also been used to build biological material, but is used to create a load bearing structure for the first time. The carrying capacity of the bridge has been tested last week. This "bio-bridge" will have at least two years of life.
Bridge will be equipped with 28 sensors for measuring body tension and the curvature of the bridge, the data will be transmitted in real time to the project team, and some data such as temperature, humidity and UV intensity within the scope of monitoring.
Project leader Rijk Blok said use of biological material in construction helps to reduce dependency on finite fossil resources, and hope that the future will see more such material is applied to the field of architecture.
荷兰建起生物大桥：由大麻和亚麻纤维制成 - IT资讯
为了寻找一个比传统建筑材料更具可持续性的建筑材料，来自四所荷兰大学的学生建造了一个长为14米，仅供行人通行的桥，由大.麻和亚麻纤维制成。这个所谓的“生物桥”位于荷兰埃因霍温，即将对公众开放。
该项目始于1月份，6月份时构建桥体模型，8月份开始最后一阶段建设直至上周才全部完成。
大麻和亚麻纤维被嵌入聚乳酸泡沫芯层夹层内，再向内填入生物树脂，它会变硬并与纤维结合在一起，最终合成生物复合材料。一些建筑材料如钢铁、混凝土或碳纤维虽然会比该生物复合材料更坚固，但在取材丰富性和环境有益性上却远远不及。该材料具有低密度的特点，可生物降解和堆肥。
尽管生物材料过去也曾被用于建设，但被用于创建承载结构还是第一次。桥的承载能力上周也已通过测试。这座“生物桥”至少将拥有两年的寿命。
桥上将装有28个传感器，用于测量桥体张力和弯曲度，这些数据将实时传送到项目团队处，一些数据如温度、湿度和紫外线照射强度也在监测范围内。
项目负责人Rijk Blok表示，在建筑里使用生物符合材料有利于减少对有限的化石资源的依赖，希望将来可以看到更多的类似材料被应用到建筑领域。
