Effects of multi walled carbon nanotubes and multilayer graphene on the damping and quasi-static compressive mechanical properties of novel EP/ZA22 composites

Journal of Composite Materials (2022)

Haoyuan Niu Fuxing Yin Puguang Ji Zhixian Jiao Jianjun Zhang

In order to develop novel high damping materials with excellent compressive mechanical properties and energy absorption capacity to meet the needs of buffering and vibration reduction in various fields, epoxy resin (EP) filled foam Zn-22Al (ZA22) composites were fabricated for the first time. EP can significantly improve the damping and compressive mechanical properties of the ZA22 foam due to the superposition of multiple damping sources and the support of EP to pores, respectively. However, the filling of EP will lead to brittleness in the compression process of the composites. It is found that the addition of multi walled carbon nanotubes (MWCNTs) or multilayer graphene (MLG) to EP can efficiently improve the toughness of the composites because of the increased energy consumption in the fracture process of EP, and the damping can also be further improved due to the increased interface density and the amount of polymer chains involved in friction.

Synthesis and properties of a novel high temperature pyridine‐containing phthalonitrile polymer

Journal of Polymer Science Part A Polymer Chemistry (2016)

Zhenjie Xi Xinggang Chen Xiaoyan Yu Yuanhui Ma Puguang Ji

ABSTRACT A novel pyridine‐containing aromatic phthalonitrile monomer, 2,6‐bis[4‐(3,4‐dicyanophenoxy)benzoyl]pyridine (BCBP) was synthesized from the nitro displacement of 4‐nitrophthalonitrile by the phenoxide of 2,6‐bis (4‐hydroxybenzoyl)pyridine (BHBP). 4‐(Aminophenoxy) phthalonitrile (APPH) was selected to promote the curing reaction, and the curing behavior has been investigated by differential scanning calorimetric (DSC), suggesting a wide processing window about 64 °C. Different curing additive concentrations resulted in polymers with different crosslinking degrees and subsequently influenced the performance of resins. The resulting BCBP polymer exhibited high glass transition temperatures exceeding 400 °C, outstanding thermo‐oxidative stability with weight retention of 95% at 530 °C, indicating a significant improvement in thermal properties endowed by pyridine units. Additionally, it also showed a lower overall water absorption after submersion in boiling water for 50 hours. © 2016 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym.

Microstructure and mechanical properties of stainless steel clad plate welding joints by different welding processes

Science and Technology of Welding & Joining (2020)

Weihe Yu Baoxi Liu Cuixin Chen M. Y. Liu X. Zhang

This work aims to study the microstructure and mechanical properties of stainless steel/carbon steel clad plate joints with three welding types: welding without transition layer, welding with transition layer using tungsten inert gas arc welding and shielded metal arc welding, respectively. Both of transition layer-weld metals contain ferrite + austenite phases obtained by different solidification modes. The brittle martensite zone is formed in the stainless steel weld metal without the transition layer because of the excessive diffusion of Cr, Ni elements. The clad plate joints with transition layer welded by shielded metal arc welding achieved the best welding quality without excessive alloy element dilution or formation of brittle phase, which reveals a perfect welding joint without obvious hardness gradient and obtains outstanding mechanical properties.

A Phthalonitrile Resin with a Low Melting Point and High Storage Modulus Containing High‐Density Aromatic Ether Bonds

ChemistrySelect (2020)

Xiaoyu Shi Shengnan Bai Puguang Ji Kimiyoshi Naito Xiaoyan Yu

Abstract A low melting point phthalonitrile monomer named 4,4′‐((((((2‐cyano‐1,3‐phenylene)bis(oxy))bis(4,1‐phenylene))bis(oxy))bis(4,1‐phenylene))bis(oxy))diphthalonitrile (BOPN), was synthesized by nucleophilic substitution of 4,4′‐oxydiphenol with 2,6‐dichlorobenzonitrile. The BOPN resin containing high‐density aromatic ether bonds were prepared via bulk addition polymerization. Two kinds of polymers were prepared from BOPN monomer by using 4‐(aminophenoxy)phthalonitrile (APPH) as the curing agent under different curing procedures. The chemical structure of the monomer was determined by Nuclear Magnetic Resonance spectroscopy (NMR) and Fourier Transform Infrared spectroscopy (FTIR). Dynamic Mechanical Analysis (DMA) demonstrated that the storage modulus of the resin at room temperature was 3712 MPa and the glass transition temperature was above 400 °C. Differential Scanning Calorimetric (DSC) analysis and rheological test indicated that the melting point and processing window of the monomer were 92 °C and 118 °C, respectively. The temperature for 95 % weight retention of the polymer in air was 529 °C.
