研究了温度变化对木塑复合材料弯曲性能的影响.试验结果表明,PE/木粉木塑复合材料的弯曲强度在6℃左右达到最大值,当温度升高或降低时,材料的弯曲强度和弯曲模量也降低;木塑复合材料的弯曲强度和弯曲模量随着木质纤维掺量的增加而增大,在木粉掺量为65%时弯曲强度达到最大值.因此,可以根据使用环境的不同,选择合适的配方生产木塑复合材料. 相似文献

The Navy Demonstration Project is a multi-layered collaborative research project between architects, material, and structural engineers the end product of which is a 5,400 square foot demonstration building for the U.S. Navy designed and built by architecture students at the Wood Materials Engineering Laboratory on the campus of Washington State University (Figures 1, 2). The project is a unique combination of design and science; it engages a series of experiments with new material development in the field of plastic wood composites, building envelope design and structural engineering. On the one hand, the project was an exploration into design possibilities inherent in engineered products such as wood-plastic composites, Oriented Strand Board (OSB), Laminated Veneer Lumber (LVL) and I-joists; on the other hand, the project was an exploration of the engineering potentials in these same materials. The building is possibly the first in the world to use wood-plastic composites so extensively and for such a wide variety of applications. 相似文献

填料对木塑复合材料弯曲性能的影响 总被引:1,自引:0,他引:1
大掺量添加填料可以大幅度地降低生产成本,但同时也会对材料性能产生一定影响.试验研究了木粉、碳酸钙、粉煤灰的掺量对木塑复合材料弯曲性能的影响.结果表明:随着木粉掺量的增加,木塑材料的弯曲强度先增加后降低,当木粉掺量达到60%时,弯曲强度达到最大值.随着碳酸钙掺量的增加,木塑材料的弯曲强度先增加后降低,当其掺量达到30%时,弯曲强度达到最大值,掺加粉煤灰也呈现相同规律. 相似文献

采用热重分析法和锥形量热仪测试方法研究硼化合物Na2B8O13.4H2O和2ZnO.3B2O3.3.5H2O对PVC木塑复合材料(WF-PVC)热解和燃烧过程的影响。结果表明:Na2B8O13.4H2O对WF-PVC热解过程影响较小,2ZnO.3B2O3.3.5H2O使WF-PVC热解过程的残炭量从18.04%提高到27.57%。与未经处理的WF-PVC相比,加入硼化合物均使燃烧过程的总热释放量(THR)和总烟释放量(TSP)降低,其中,2ZnO.3B2O3.3.5H2O使THR和TSP分别降低36.3%和55.8%,阻燃和抑烟效果显著。2ZnO.3B2O3.3.5H2O在WF-PVC中阻燃作用以凝聚相为主,同时伴随气相中的化学作用;Na2B8O13.4H2O在WF-PVC中为凝聚相作用机理。 相似文献
