Prof. Peng Huaxin, distinguished expert of the national long-term thousand talents of the School of Materials Science and Engineering, as a correspondence author, his review paper Microstructurally Inhomogeneous Composites: Is a homogeneous reinforcement distribution optimal? has been published online in the internationally renowned journal Progress in Materials Science in February 2015.
Progress in Materials Science is an authoritative review of academic journals in the field of international material science research. It has an important influence in the material industry. It is published 6-8 issues a year, with 1-3 articles per issue. The impact factor in 2014 was 25.87. This paper is the third large-scale review paper published by Prof. Peng Huaxin as a correspondence author in the journal since 2008.
Prof. Peng Huaxin was selected in the tenth batch of national long-term thousand talents in 2014. In June 2014, he resigned as a professor at the University of Bristol, UK, and joined the School of Materials Science and Engineering Zhejiang University. Main research directions: aerospace fiber reinforced resin matrix composites; multifunctional composite materials; metal-ceramic composites; nanocomposites and coatings; microstructure design at nano, micro and mesoscale.
For the two-phase (reinforced phase and matrix phase) composites, under the guidance of traditional composite theory, for half a century, people have been pursuing the uniform distribution of the reinforcing phase in the matrix. On the basis of developing new composite materials theory, Prof. Peng Huaxin proposed a new concept that can improve the comprehensive performance of composite materials more effectively by regulating the phase distribution state, breaking the traditional concept of uniform distribution of enhanced phases, and then achieving a variety of composite structures with better reinforcement and toughening effects.These new composite structures are suitable for composites and multifunctional composites on the nano, micro, and mesoscale scales. Associate Professor Huang Lujun and Prof. Geng Lin from Harbin Institute of Technology, co-author of the paper, designed and developed aluminum-based, titanium-based and TiAl-based composites with superior performance in agglomerated, networked and layered distribution.This review reviews the research results in this field for many years, and looks forward to the development direction of the enhanced phase controllable non-uniform distribution composites. The full text is of 76 pages, cited 276 references.
Fig. 1. Schematic illustrations and representative SEM images (insets) of microstructural inhomogeneity with four different patterns of reinforcement-rich phase. (a) Pattern A: isolated, (b) Pattern B: bar/laminated/ring-like, (c) Pattern C: 3D network with isolated particle-lean phase and (d) Pattern D: 3D network with interconnected particle-lean phase forming the so-called bi-continuous microstructure. (Pattern A is similar to that used by Corbin & Wilkinson [30] and Tseng [31]. The four insets are the corresponding real microstructures of composites selected from published work that will be introduced in the following sections.)
