损伤开裂是目前影响沥青路面结构耐久与行车安全的重要因素之一。路用灌注式半柔性材料(SFM)通过在沥青混凝土骨架中灌注水泥浆,兼具水泥和沥青特性,具有较好的耐久性及行车舒适性,但SFM界面处由于各相材料变形不协调易引发细观损伤。为了揭示半柔性材料在温度变化过程中的界面损伤,利用有限元分析方法,通过引入内聚力模型(CZM)对SFM界面区域在不同温域下黏结-失效过程进行了模拟分析。首先,以25%目标空隙率设计SFM的骨架沥青混合料,在对其进行基本性能测试后灌注水泥浆,制备SFM试件。然后通过工业CT扫描,获得SFM的内部截面几何信息,构建细观有限元模型。分别对SFM组分包括开级配沥青混合料、水泥灌浆料以及集料进行不同温度范围内的温缩行为测试,将试验获得的线收缩系数输入有限元模型中进行计算,研究其界面区域在经历不同温域后的应力集中、失效程度及损伤分布等问题。结果表明:与多数工况类似,在从20℃向―30℃降温过程中,SFM内部应力主要集中于集料-沥青-水泥灌浆料界面区域。通过对各降温区段的应力大小及损伤程度分析后,发现20℃至10℃降温区间内,沥青膜黏结强度及断裂能最小且承受的不协调变形最大,因此该降温区间内SFM界面处损伤开裂最严重。

A model of non-uniform height rectangular fin, in which the variation of base's thickness and width are taken into account, is established in this paper. The dimensionless maximum thermal resistance(DMTR) and the dimensionless equivalent thermal resistance(DETR) defined based on the entransy dissipation rate(EDR) are taken as performance evaluation indexes. According to constructal theory, the variations of the two indexes with the geometric parameters of the fin are analyzed by using a finite-volume computational fluid dynamics code, the effects of the fin-material fraction on the two indexes are analyzed. It is found that the two indexes decrease monotonically as the ratio between the front height and the back height of the fin increases subjected to the non-uniform height rectangular fin. When the model is reduced to the uniform height fin, the two indexes increase first and then decrease with increase in the ratio between the height of the fin and the fin space. The fin-material fraction has no effect on the change rule of the two indexes with the ratio between the height of the fin and the fin space. The sensitivity of the DETR to the geometric parameters of the fin is higher than that of the DMTR to the geometric parameters. The results obtained herein can provide some theoretical support for the thermal design of rectangular fins.

Cordierite precursor was obtained through a process, which involved the decomposition of metal nitrates on the surface of ultrafine carbon black powder between 100-300℃ and the gasification of the carbon black at higher temperature in air. The average size of the particles, which were heat-treated at 700℃ for 10h, is about 1020nm, and the specific surface area is about 129m 2/g. The experimental results show that the ultrafine particles of cordierite precursor can be produced by this process. The precursor powder was calcined at different temperatures. X-ray diffraction examination indicates that β-quartz is crystallized from the amorphous matrix around 850℃ firstly and then MgO-Al 2O 3 spinel and α-cordierite appears. Above 1000℃, MgO-Al 2O 3 spinel and cristobalite disappear gradually and form an intermediate phase (sapphirine). At around 1300℃, the main phase is α-cordierite, and no other phase is detected.

为了考察不同投料顺序对镁合金表面层状双金属氢氧化物(LDHs)涂层性能的影响,并得到一种具有较好耐腐蚀能力的镁合金防腐蚀涂层,通过水热合成法采用不同投料顺序在镁合金表面原位沉积LDHs涂层。使用SEM、XRD、EIS、Tafel曲线和直接浸泡的方法,分别对LDHs涂层的表面形貌、结构和耐腐蚀性能进行评估。结果发现,采用不同的投料顺序得到了不同表面形貌、相似结构和不同耐腐蚀能力的LDHs涂层。所有LDHs涂层的自腐蚀电位、自腐蚀电流密度和阻抗模量相对于基底都分别发生了明显的正移、下降和增加,电位正移值约为0.7 V,自腐蚀电流密度降低值达到3~4个数量级,阻抗模量增加约4个数量级。以上结果表明通过控制投料顺序可以得到具有不同表面形貌的LDHs涂层。采用向硝酸铝中添加硝酸镁后调节溶液p H,再加入碳酸钠的投料顺序,得到LDHs涂层在NaCl溶液中的耐腐蚀能力最好。

The emerging biomass-based epoxy vitrimers hold great potential to fulfill the requirements for sustainable development of *** the existence of dynamic chemical bonds in vitrimers often reduces both the thermal and mechanical properties of epoxy resins, it is challenging to produce recyclable epoxy vitrimers with both excellent mechanical properties and good thermal stability. Herein, a monomer 4-(((5-(hydroxymethyl)furan-2-yl)methylene)amino)phenol(FCN) containing furan ring with potential to form high density of hydrogen bonding among repeating units is designed and copolymerized with glycerol triglycidyl ether to yield epoxy resin(FCN-GTE), which intrinsically has dual hydrogen bond networks, dynamic imine structure and resultant high performance. Importantly, as compared to the BPA-GTE, the FCN-GTE exhibits significantly improved mechanical properties owing to the increased density of hydrogen bond network and physical crosslinking interaction. Furthermore, density functional theory(DFT) calculation and in situ FTIR analysis is conducted to decipher the formation mechanism of hydrogen bond network. In addition, the FCN-GTE possesses superior UV shielding, chemical degradation, and recyclability because of the existence of abundant imine bonds. Notably, the FCN-GTE-based carbon fiber composites could be completely recycled in an amine *** study provides a facile strategy for synthesizing recyclable biomass-based high-performance epoxy vitrimers and carbon fiber composites.
