A polymeric natural fiber-reinforced composite is developed by extrusion and injection molding process. The shrinkage and warpage of high-density polyethylene reinforced with short natural fibers of Guadua angustifolia Kunth are analyzed by experimental measurements and computer simulations. Autodesk Moldflow® and Solid Works® are employed to simulate both volumetric shrinkage and warpage of injected parts at different configurations: 0 wt.%, 20 wt.%, 30 wt.% and 40 wt.% reinforcing on shrinkage and warpage behavior of polymer composite. Become evident the restrictive effect of reinforcing on the volumetric shrinkage and warpage of injected parts. The results indicate that volumetric shrinkage of natural composite is reduced up to 58% with fiber increasing, whereas the warpage shows a reduction form 79% to 86% with major fiber content. These results suggest that it is a highly beneficial use of natural fibers to improve the assembly properties of polymeric natural fiber-reinforced composites.
关键词: biocomposite natural fiber shrinkage simulation warpage

城市地铁区间隧道爆破施工中面临的一个重要问题就是降低爆破振动对临近地表建筑物的影 响。青岛地铁一期工程03号线03标段下穿建筑物时,为了确保距隧道拱顶5~8 m的地表建筑物安全,采 用了大中空孔直眼掏槽技术、一次起爆分部延时爆破、浅孔多眼等技术,将地表建筑物最大垂直振速控制 在国标允许范围之内,隧道通过后地表建筑物完好无损。并在施工中解决了大断面隧道爆破施工导爆管 雷管段数不能满足施工要求、分断面施工不能同时实施爆破作业,施工效率低下的问题,既保证了工程施 工安全又满足了进度要求。

MABR exhibits excellent TN removal performance for treating ROC with low C/N ratio. Operating conditions should be properly controlled to achieve optimal TN removal. Denitrifying bacteria and NOB are proved notably inhibited by high salinity stress. The TN removal rate remains over 70% when the NaCl addition amount is below 20 g/L.
