Processing, Microstructure, and Performance of Robocast Clay-Based Ceramics Incorporating Hollow Alumina Microspheres

Materials (2024)

Yanfang Wu Junjie Lan Mingxuan Wu Ming-jun Wu Tian Li

The restoration of ancient ceramics has attracted widespread attention as it can reveal the overall appearance of ancient ceramics as well as the original information and artistic charm of cultural relics. However, traditional manual restoration is constrained due to its time-consuming nature and susceptibility to damaging ancient ceramics. Herein, a three-dimensional (3D) printing technique was employed to accurately restore Chinese Yuan Dynasty Longquan celadon using hollow Al2O3 microsphere-modified 3D printing paste. The results show that the hollow Al2O3 microsphere content plays a vital role in the printability, physical properties, and firing performance of the modified 3D printing paste. The printed green bodies show no noticeable spacing or voids under moderate rheological conditions. The as-prepared ceramic body modified with 6 wt.% hollow Al2O3 microspheres and fired at 1280 °C exhibits optimal bending strength of 56.66 MPa and a relatively low density of 2.16 g∙cm−3, as well as a relatively uniform longitudinal elastic modulus and hardness along the interlayer. This 3D printing technique based on hollow Al2O3 microsphere-modified paste presents a promising pathway for achieving non-contact and damage-free restoration of cultural relics.

Synthesis of unsaturated polyester resin based on dicyclopentadiene by two step method

Thermosetting Resin (2005)

Ming-jun Wu

Dicyclopentadiene(DCPD)type unsaturated polyester resin(UPR)for polyputty was prepared by two step method.The amount of every kind of material which would affect on resin and polyputty′s property was studied.When n(maleic anhydride)∶n(industrial DCPD)∶n(refined DCPD)∶n(di-alcohols)=2.0∶0.7∶0.5∶1.75,the properties of UPR were stable.The polyputty′s general properties,such as air-drying,heat resistance,grindability,knife coating property,toughness were excellent.

Analysis of the Mechanical Response of Asphalt Pavement Under Water-Stress Coupling

Advances in transdisciplinary engineering (2021)

Kun Wang Ming-jun Wu Peng Hu Baoqun Wang

In order to study the mechanism of water damage of an asphalt pavement, the FLAC3D program was adopted to model and analyze the mechanical response of a saturated asphalt pavement under instantaneous vehicle load. The results show that the horizontal stress, vertical stress and shear stress of an asphalt concrete pavement increase with the increase of instantaneous load. The surfaces of asphalt pavement structural layers are most vulnerable to damage. The horizontal stress, vertical stress and shear stress decrease sharply with the instantaneous dynamic load decreasing to zero. The horizontal stress reaches maximum value at the interface between the base and the large stone porous mixture (LSPM) layer, while the maximum vertical and shear stresses occur on the surface layer of the saturated asphalt pavement. The deformation decreases almost linearly from the surface of the asphalt pavement to the subgrade, and the pore water pressure was little influenced by the transient load.
