    2015
    Co-Authors: G V Pujari, V R Naik
    Abstract:

    This paper describes about the parameter optimization using the combination of design of experiment (DOE) Taguchi method and Moldflow simulation tests By this method, it can gain the experiment data which can reflect the overall situation using fewer number of simulation test. Furthermore, the effects degree of different Molding process parameters for surface sink marks are investigated, optimized parameter combination is obtained. It can solve the unreasonable appearance of process parameter settings. The mold design above mentioned can fasten the mold developing schedule, thus shorten the cycle of product development, and improve the quality of products and the competitive ability of enterprise.

  • method for manufacturing interlayer micro bar reinforced continuous fiber reinforced composite additive
    2019
    Co-Authors: Tian Xiaoyong, Zhu Weijun, Luo Meng, Shang Junfan, Li Dichen
    Abstract:

    Provided is a method for manufacturing an interlayer micro bar-reinforced continuous fiber reinforced composite additive. Firstly, the integrated process of preparation and forming of a composite is completed, and a target workpiece is obtained; fibers are soaked with resin, forming is carried out through a micro-diameter rod pultrusion process, and a micro bar is obtained through shearing; the micro bar is loaded into a nail gun, and is shot into the target workpiece subjected to environmental heating and softening in advance; if the target workpiece is a plate part with the thickness smallerthan 3 cm, the micro bar only needs to be embedded once; otherwise, the micro bar needs to be embedded more than one times until the thickness of the target workpiece meets the target requirement; and finally the target workpice with the micro bar implanted is placed in a constant-temperature chamber to be subjected to heating aftertreatment, and the target workpiece and the micro bar form a goodbonding interface. According to the method, a high-performance continuous fiber reinforced composite extrusion Molding Component with balanced or controllable properties is fast manufactured.

  • comparison of ductile fracture properties of aluminum castings sand mold vs metal mold
    International Journal of Solids and Structures, 2008
    Co-Authors: Hiroyuki Mae, Xiaoqing Teng, Yuanli Bai, Tomasz Wierzbicki
    Abstract:

    Abstract This paper compares mechanical properties of two types of cast aluminum Components made in sand molds and cast iron molds, respectively. For each type of the castings, a total of 12 fracture tests are performed under a wide range of stress states including 6 tensile tests on notched and unnotched round bars and 6 biaxial loading tests on butterfly specimens. Using a combined experimental–numerical approach, the plasticity and fracture properties of the Components are characterized in terms of the true stress–strain curve and the ductile fracture locus. It is found that the sand-Molding Component is of higher yield resistance and lower ductility than the metal-Molding one. Meanwhile, the fractographic study reveals that there exist two competing failure mechanisms: the internal necking of the matrix at high positive stress triaxialities and void sheeting due to shear at negative stress triaxialities. The transition of the failure modes occurs in the intermediate range. This suggests that a ductile fracture locus formulated in the space of the stress triaxiality and the effective fracture strain consist of three branches rather than a monotonic curve.

  • pneumatic mold aided construction of a three dimensional hydrogel microvascular network in an integrated microfluidics and assay of cancer cell adhesion onto the endothelium
    Microfluidics and Nanofluidics, 2013
    Co-Authors: Jianchun Wang, Yaolei Wang, Wenming Liu, Rui Liu, Shaofei Shen, Lei Zhao, Jinyi Wang
    Abstract:

    A pneumatic microchannel network (PμCN) fabrication method for producing a three-dimensional microvascular system in an integrated microfluidic device is described. The spatial dynamics of the PμCN profile is systematically characterized and quantitatively analyzed. A microvessel network-embedded hydrogel scaffold is constructed using in situ pneumatic actuation of the PμCN and collagen polymerization. The endothelium-containing microvasculature, which has high cell viability and typical vascular features, was formed by seeding and cultivating human umbilical vein endothelial cells (HUVEC-C). Furthermore, a quantitative investigation of the adhesive interactions between breast cancer cells and endothelial cells was performed with vascular tissue-mimicry in the hydrogel-supported endothelial network using human breast cancer cells (MDA-MB-231) and HUVEC-C cells. The results show signal-promoted and region-preferred adhesion of cancer cells in the established microvascular network. The PμCN can be applied as an active microfluidic Molding Component for convenient and robust reproduction of microvasculature in vitro. PμCN application can be valuable in monitoring and investigating blood vessel-involved physiologic/pathologic processes. Moreover, this method will facilitate controllable parenchymal tissue organization and construction for tissue engineering as well as subsequent applications for clinical medicine.
