Preparation of Pre-Impregnated Continuous Carbon Fiber Reinforced Nylon6 Filaments and the Mechanical Properties of 3d Printed Composites

Yuexi Zhuang Bin Zou Shouling Ding Xinfeng Wang Jikai Liu

The addition of continuous fibers as the reinforcement is considered to be an effective option to promote the mechanical properties of 3D printed parts. In this paper, different types of prepreg continuous fiber filaments for 3D printing were prepared, and the effects of fiber types and content on the tensile strength of filaments were investigated. Moreover, the prepared filaments were also applied to 3D printing continuous fiber reinforced composite parts. The effects of the infiltration degree on the properties and its strengthening mechanism were studies by failure morphologies. The results showed that the strength of filament was influenced by both internal infiltration degree and resin content, at the same fiber content, the tensile modulus of the filament increases with resin content, and the maximum tensile force can reach 0.21 MPa (3k-0.68). The tensile strength of the sample is negatively correlated with the fiber content in the filament, while the shear strength is positively correlated with the fiber content. At the printing temperature of 280 Â°C, the printed samples show better tensile and shear properties of 189 MPa and 29 MPa, respectively.

Accuracy Analysis of Numerical Simulation in Seepage Field of Gravity Dam Foundation with Fluent

Water Resources and Power (2011)

Xinfeng Wang

In order to explore the accuracy of porous module in simulating seepage field of gravity dam foundation,the Fluent of numerical simulation based on finite volume method is used to solve seepage field of dam foundation.Taking numerical simulation of 2D semi-infinite deep steady seepage field of simple underground contour line for an example,without regard to multi-physical filed coupling,exact solutions of each measure point characteristics are calculated with seepage theory.Compared with the simulation results of the same point characteristics obtained by Fluent post-processing program,it shows that numerical simulation error by porous media module of Fluent based on finite volume method is less than 3%,which meets project required precision.

Geometric Structures for Sialon Ceramic Solid End Mills and Its Performance in High-Speed Milling of Nickel-Based Superalloys

Coatings (2023)

Kai Xue Peng Chen Wenbo Liu Bin Zou Lei Li

Sialon ceramic tool material has become one of the most ideal materials for the high-speed cutting of superalloy materials. However, studies on the geometric structure of sialon ceramic solid end mill is lacking at the present. In this work, the geometric structure of sialon ceramic end mills was designed for difficult-to-machine nickel-based superalloy materials. The cutting force and heat, flank wear and machined surface quality were analyzed to study the effect of the main parameters on tool performance. The results showed that the end mill experienced severe flank wear and chipping, which were the leading cause of its failure during high-speed cutting. The cutting force and temperature decreased gradually with the increase in the helix angle. With the increase in the rake angle, the flank wear and the quality of the machined surface of the specimen first decreased and then increased. With the increase in the relief angle, the cutting temperature of the ceramic end mill gradually decreased, and the cutting force and the machined surface roughness showed an initial decrease and then increased. When the helix angle, rake angle and relief angle were 35°, −15° and 12°, respectively, the sialon ceramic end mill exhibited the best cutting performance and obtained better machined surface quality in the nickel-based superalloys.

Prefix Subsection Matching Binary Algorithm in Passive RFID System

兵工学报(英文版) (2011)

Xinfeng Wang

Identifying speed,tag average response times and reliability are the most important capabilities in passive RFID(radio frequency identification) system.QT(query tree) is a famous algorithm for lowest-cost RFID tags,but its shortcoming is high searching delay and high tag average response times.A prefix subsection matching binary(PSMB) algorithm based on QTalgorithm is proposed.The key idea of PSMB anti-collision algorithm is that,during searching phase,a given reader uses the particular tags ID,which has been searched out formerly,to shorten searching delay and depress tag average response times.The idea of PSMB algorithm can be described as follows.Usually,tag ID is composed of several subsections which have different meanings.Based on the tags ID searched out formerly,a given reader builds a prefix database.In subsequent searching phase,the reader uses its prefix database to deduce searching space of tag ID.Simulation results show that identification delay of PSMB algorithm is about 1/3 of QTalgorithm,tag average response times is about 1/4 of QTalgorithm,and system throughput rate is treble QTalgorithm.
