3D Printing of Continuous Fiber Reinforced Polymer Composites:Development,Application,and Prospective

Continuous fiber reinforced polymer composites(CFRPC)have been widely used in the field of automobile,air-craft,and space due to light weight,high specific strength and modulus in comparison with metal as well as alloys.Innovation on 3D printing of CFRPCs opened a new era for the design and fabrication of complicated composite structure with high performance and low cost.3D printing of CFRPCs provided an enabling technol-ogy to bridge the gaps between advanced materials and innovative structures.State-of-art has been reviewed according to the correlations of materials,structure,process,and performance as well as functions in 3D printing of CFRPCs.Typical applications and future perspective for 3D printing of CFRPCs were illustrated in order to grasp the opportunities and face the challenges,which need much more interdisciplinary researches covering the advanced materials,process and equipment,structural design,and final smart performance.

Materials-oriented integrated design and construction of structures in civil engineering—A review

Design is a goal-oriented planning activity for creating products,processes,and systems with desired functions through specifications.It is a decision-making exploration:the design outcome may vary greatly depending on the designer’s knowledge and philosophy.Integrated design is one type of design philosophy that takes an interdisciplinary and holistic approach.In civil engineering,structural design is such an activity for creating buildings and infrastructures.Recently,structural design in many countries has emphasized a performance-based philosophy that simultaneously considers a structure’s safety,durability,serviceability,and sustainability.Consequently,integrated design in civil engineering has become more popular,useful,and important.Material-oriented integrated design and construction of structures(MIDCS)combine materials engineering and structural engineering in the design stage:it fully utilizes the strengths of materials by selecting the most suitable structural forms and construction methodologies.This paper will explore real-world examples of MIDCS,including the realization of MIDCS in timber seismic-resistant structures,masonry arch structures,long-span steel bridges,prefabricated/on-site extruded light-weight steel structures,fiber-reinforced cementitious composites structures,and fiber-reinforced polymer bridge decks.Additionally,advanced material design methods such as bioinspired design and structure construction technology of additive manufacturing are briefly reviewed and discussed to demonstrate how MIDCS can combine materials and structures.A unified strengthdurability design theory is also introduced,which is a human-centric,interdisciplinary,and holistic approach to the description and development of any civil infrastructure and includes all processes directly involved in the life cycle of the infrastructure.Finally,this paper lays out future research directions for further development in the field.

Dispersed distribution derived integrated anode for lithium ion battery

With the development of portable communication devices and electric vehicles, there is a great need for energy storage devices with lighter weight and higher energy density. In this paper, a new method by combining waster-paper-synthesized conductive paper(CP) and active material Mn O2 together is developed to obtain a new type of anode without any binder for lithium ion batteries. By this way, we can obtain low density anode with active material in CP, instead of the commonly-used heavy metal current collector. Also, binder has been abandoned, which are usually used to combine active material into anode, to further decrease weight. The multi walled carbon nanotube(MWCNT) was added in serves as a component of CP and the conductive agent for active material. Compared to traditional anode coated on Cu current collector, the CP-combined anode can greatly improve the electrochemical performance of active material Mn O2. It can let more particles to fully participate in the reaction and therefore boost the specific capacity to a great extent(about 3 times higher). It delivered an initial specific capacity of 1629.9 m A h g^-1 at a current density of 100 m A g^-1 and maintained about 67% even after 100 cycles.What’s more, it shows reversible capacity of about 260 m A h g^-1 at high current density of 1000 m A h g^-1.Our original synthesis method of anode, which shows far-reaching referential value and environmental significance, can be generalized to other electrodes and other battery systems.
