Adhesively Bonded Carbon Fibre Reinforced Plastic(CFRP)and titanium alloy have been extensively used as a hybrid structure in modern aircrafts due to their excellent combination of mechanical properties and chemical *** study utilised NaOH anodising method to create micro-rough titanium surfaces for enhancing adhesive bonding between titanium alloy and CFRP laminates.A special and simple technique named Resin Pre-Coating(RPC)was also employed to improve the surface wetting of anodised titanium and grinded CFRP *** influences of anodising temperature and duration on the surface morphology,wettability and adhesive bond strength were *** single lap shear test results showed that the bond strength of specimens anodised at 20℃for 15 min improved by 135.9%and 95.4%,respectively,in comparison with that of acid pickled and grinded specimens(without RPC treatment).Although increasing the anodising temperature and duration produced rougher titanium surfaces,the adhesively bonded joints were not strong enough due to relatively friable titanium oxide layers.

The high-strength Basalt Carbon Fiber Reinforced Polymer(BCFRP)composites had been manufactured by guiding Imitating Tree-root Micro/Nano Aramid Short Fiber(ITMNASF)into the interlayer of Basalt Fiber(BF)and Carbon Fiber(CF)plies to form thin interleaving,and various mass proportions of IT-MNASF were designed to discuss the reinforcing effect on the BCFRP heterogeneous *** results of three points bending tests showed that flexural strength and energy absorption of 4wt%IT-MNASF reinforced BCFRP heterogeneous composites had been improved by 32.4%and 134.4%respectively compared with that of unreinforced *** 4wt%IT-MNASF reinforced BCFRP specimens showed both a greater strength and a lower cost(reduced by 31%around)than that of plain CFRP composites.X-ray micro-computed tomography scanning results exhibited that the delamination-dominated failure of plain BCFRP composites was changed into multi-layer BF and CF fabrics *** reinforcing mechanism revealed that the introduced IT-MNASF could construct quasi-vertical fiber bridging,and it was used as"mechanical claws"to grasp adjacent fiber layers for creating a stronger mechanical interlocking,and this effectively improved resin-rich region and interfacial transition region at the *** simple and effective IT-MNASF interleaving technique was very successful in low-cost and high-strength development of BCFRP heterogeneous composites.

节能环保产业的高质量发展,是我国实现创新驱动战略和绿色低碳转型的重要引擎。然而节能环保产业政策对企业技术创新是发挥资源补偿效应还是挤出效应?企业的策略性创新行为对选择不同创新类型有何影响?目前学界尚未达成共识。本文以《关于加快发展节能环保产业的意见》的出台为准自然实验,运用双重差分模型实证检验了节能环保产业政策对企业创新的影响效果及作用机制。研究发现:(1)节能环保产业政策会在非绿色技术创新活动上诱发“资源补偿效应”,但企业总是以策略性非绿色创新来回应政府扶持,从而引致了对绿色创新的“挤出效应”。(2)节能环保产业政策尚未提升公众的环境关心水平;研发投入是产业政策引发策略性非绿色创新效应的关键传导因素。(3)小规模企业和市场化程度高的地区的企业更明显地受到政策干预而进行创新活动,但是实质性创新和绿色创新的动力不强。本文对推动节能环保产业的绿色低碳高质量发展具有一定的启示。

经甘油增塑的淀粉对湿度敏感、易老化。本研究采用一步法制备超支化聚均苯三甲酸丁二醇酯(H),并与甘油(G)作为玉米淀粉(CS)的共增塑剂混合制备淀粉薄膜。采用傅里叶变换红外光谱(FTIR)和核磁共振氢谱(^(1)H NMR)证实了超支化聚均苯三甲酸丁二醇酯的结构,并研究了共增塑剂对淀粉相互作用、结晶度、拉伸性能、抗老化性、热稳定性、透光率和吸湿性的影响。结果表明,聚均苯三甲酸丁二醇酯/甘油对淀粉薄膜的韧性、抗老化、透光性和吸湿性有协同作用。聚均苯三甲酸丁二醇酯/甘油配比为5/25的淀粉薄膜(CS/H5G25)具有最大的断裂伸长率、最高的透光率、最佳的抑制淀粉重结晶的能力以及最低的吸湿率(RH>68%)。CS/H2G28薄膜储存3、15和30 d的断裂伸长率分别为85.9%、103.1%和77.2%,分别是CS/G薄膜的2.8倍、2.3倍和3.7倍。这不仅取决于各组分之间的相互作用,还可能与组分之间的相容性有关。聚均苯三甲酸丁二醇酯/甘油在增塑淀粉方面具有潜在的应用价值。
