It is a huge challenge to achieve highly efficient fire retardance with no mechanical damage polymers. In our current research, novel core–shell titanium dioxide@diphenylphosphinic (TiO2@DPP) nanosphere was first synthesized through hydrothermal reacting process, and applied in simultaneously enhancing the properties of polycarbonate (PC). The well-designed TiO2@DPP exhibited significant effect on combustion performance reinforcement PC. At only 0.10 wt % TiO2@DPP, PC/TiO2@DPP passed UL-94...
Aluminium alloys are difficult to be manufactured by directed energy deposition (DED) with the widely used infrared laser because of low absorptivity. A blue a 450 nm wavelength has significantly higher absorptivity in processing aluminium. Here, we developed 2000 W (BL-DED) system for additive manufacturing. In this system, coaxial camera, paraxial high-speed and camera were simultaneously adopted analyze formation evolution molten pool characteristics. The relationships among...
High thermal conductivity and large fluctuations in laser absorptivity with temperature make aluminum alloy prone to deformations, collapses, spheroidization, other defects during directed energy deposition (DED) processes. To achieve stable high-quality annular DED (AL-DED) of alloy, an situ field assistance system was designed, wherein a preheating-cooling control balance model established. The effect the AL-DED process AlSi10Mg has been evaluated, ability on analyzed. A continuous...
Recently, there are many efforts attempting to learn useful policies for continuous control in visual reinforcement learning (RL). In this scenario, it is important a generalizable policy, as the testing environment may differ from training environment, e.g., exist distractors during deployment. Many practical algorithms proposed handle problem. However, best of our knowledge, none them provide theoretical understanding what affects generalization gap and why their methods work. paper, we...
Hydrocarbon-based phase change materials (PCMs) are accompanied by an inherent fire risk, which is hindering their further application especially in construction. Molecular-firefighting PCMs can be ideal and promising candidates to simultaneously ensure the highly efficient energy management safety of PCMs. In this work, two novel phosphorus/nitrogen-containing ionic liquids ([DP][MI] [DP][TEA]), composed imidazole (MI) or triethylamine (TEA) cations dicetyl phosphate (DP) anion, were...
In this paper, the skin-core combined with triple contour method is proposed to solve density and roughness problems of selective laser melting. Based on strategy, surface optimized by parameter adjustment, high-quality side-surface formation achieved method. The results showed that relative increases first then decreases increasing in-skin energy density, up-skin density. effects parameters have been analyzed. addition, a scanning strategy was also conducted, variation caused different...
Titanium oxide-carbon nanotube hybrids may efficiently promote the stability of nature rubber under extreme frictional conditions.
Aircraft tires face extremely complex conditions during landing and the sharp temperature rise that is caused by friction in a short period of time may bring about serious destruction to tread compound thus threat on safety aircraft. Our research described here focused high-temperature stability carbon black enhanced natural rubber (NR) composite at high temperatures (300-400 °C) (0-100 s) ranges its effect mechanical properties, deep investigation corresponding mechanisms. The experimental...
In this paper, a novel surface finishing method of cone annular beam laser re-melting (CALR) is proposed which aims at optimizing the side quality AlSi10Mg parts produced by directed energy deposition. Meanwhile, feature-based characterization was conducted to realize multiscale analysis topographic features. The results show that developed CALR powerful tool can greatly reduce roughness: final optimal aluminum alloy thin-walled with roughness 7.1 µm obtained, 68.3% less than original 22.4...
