| 1 | Investigations into the corrosive environments contributing to premature failure of Australian coal mine rock bolts显示文摘University of New South Wales(UNSW Australia) had been involved in the study of premature failure of rock bolts in Australia coal mines from the initial identification of the problem in 1999. Rock bolt steel changes over the last decade appear to have not reduced the incidence of failures. A broadened UNSW research project funded by the Australian Research Council(ARC) and Industry has targeted finding the environmental causes through extensive field and laboratory experiments. This paper describes the field studies conducted in underground coal mines,in particular attempts to measure the contribution to corrosion from groundwater,mineralogy and microbial activity. Various underground survey techniques were used to determine the extent of broken bolts,with the presence of both stress corrosion cracking(SCC) and localized deep pitting making no single technique suitable on their own.Groundwater found dripping from bolts across various coalfields in Australia were found to be not aggressive and known groundwater corrosivity classification systems did not correlate to where broken bolts were found. In-hole coupon bolts placed in roof strata containing claystone bands confirmed the clay as being a major contributor to corrosion. Microbes capable of contributing to steel corrosion were found to be present in groundwater,and culturing of the microbes taken from in-situ coupon bolts proved that the bacteria was present on the bolt surface. An ‘in-hole bolt corrosion coupon' development by the project may have multiple benefits of (1) helping quantify newly developed corrosivity classification systems,(2) providing an in-situ ground support corrosion monitoring tool,and (3) for testing possible corrosion protection solutions. | Craig P.

| 2 | 自愈合机敏复合材料综述(英文)显示文摘文摘综述了中空纤维释放黏结剂的裂纹愈合及近期开发的机敏裂纹自愈合复合材料的研究进展。对后者微胶囊促使的机敏裂纹自愈合进行了详尽的阐述,其中包括愈合剂和催化剂的结构、微胶囊的形成和外表连接催化剂、愈合剂系统原位聚合反应、纯环氧树脂基体和复合材料中的裂纹自愈合、愈合效率及愈合复合材料微观表征等方面。一个典型的双相自愈合系统是包含于微胶囊中的二聚环戊二烯(DCPD),通过埋于环氧基体中的钌络合物催化剂进行开环转位聚合反应(ROMP),形成新的聚合物来愈合裂纹。在纯环氧树脂基体中,上述自愈合系统在室温下的愈合效率可高达90%,而在碳纤维复合材料中室温下的愈合效率大致是45%,在80℃可提高到80%。降冰片烯(Norbornene)及其衍生物具有同以上系统相似的自愈合功能。三聚呋喃和四聚马来酰亚胺可在无催化剂作用下,进行热可逆的、无终止的交联聚合反应,自动愈合裂纹。同时,对以上三种自愈合剂系统及复合材料的特点进行了比较。 | 李崇俊 Alan Crosky | 2006 | 宇航材料工艺2006，36，1： | 4 |
