Modeling of their true morphologies is still fields of focus research, yet to be exhausted. In this paper, ANSYS were utilized to develop three-dimensional numerical model of fiber bundle on the computer in the way of simulation. This approach is enabled by the finite element packages. It is possible to simulate the true material morphology directly. The key issues of the simulation are to keep fiber volume fraction always a constant value and to ensure no intersection between fibers. This work can simulate the stochastic generation-growth of high-performance fiber bundle and reproduce morphology of fiber bundle on micron scale well and thereby provide reliable information for the study on the lateral compression mechanism in the future.

Published: September 2011

In this paper, a new type of LLDPE/nano CaCO3 composite based artificial turf yarns with good tensile property and UV resistance is introduced. The effect of nano CaCO3content on tensile properties shows that the tensile force reached the maximum value when the CaCO3 content is about 7wt%, and the elongation at break gets to the highest point at 10wt%. After 3000h UV accelerated aging, the nano-CaCO3 and LLDPE based artificial turf fiber yarns has tensile strength retention about 87%, and the elongation at break is higher than LLDPE. DSC results shows that with the increase of nano-CaCO3 content, the crystallization temperature gradually increased, and the crystallinity degree declined. SEM images of cross sections of monofilament fibers show that nano CaCO3 had a good dispersion in monofilament fiber matrix. These reasons give rise to the improved mechanical properties of turf yarns.

Authors: Lu Yan Yue , Liao An Ping , Hu Yang Dong
Published: September 2011

The reverse osmosis (RO) desalination process to make multiple freshwater from seawater has been studied in this work. The optimization method based on process synthesis has been applied to design the RO system. The optimum design problem can be formulated as a mixed-integer non-linear programming (MINLP) problem, which minimizes the total annualized cost of the RO system. The solution of the problem includes the optimal system structure and operating conditions, and the optimal streams distribution. The design method could also be used for the optimal selection of the types of membrane elements in each stages and the optimal number of membrane elements in each pressure vessel. The effectiveness of this design methodology has been demonstrated by solving a desalination case.

Published: September 2011

A combined process of flocculation and Fenton oxidation was studied for the treatment of polymerization effluents (PME) from the manufacture of dry-spun acrylic fibers. 5 inorganic and 3 organic flocculants were investigated and the optimal regents and conditons were PAC (at 25°C, pH=8 and a dosage of 150 mg/L), and Z7650 (at 25°C, pH=6 and a dosage of 10 mg/L). Under this condition, the COD was removed by 23.1% of the initial 1824 mg/L. The optimum efficiency of Fenton process was determined at 25°C and pH=4 with a reaction time of 90 min. The dosage of H2O2 and the rate of c(H2O2)/c(FeSO4) were respectively 0.53 mol/L and 20:1. Finally, the removal of COD, total nitrogen, ammonia, SO32- and turbidity by the combined process were 64.0%, 99.3%, 99.6%, 99.7% and 89.4% respectively. BOD/COD was also improved from 0.09 to 0.25.

3D Geometrical Model of Plain Weave Fabrics for Finite Element Analysis
Authors: Wang Dong Ning , Jiao Ya Nan , Li Jia Lu
Published: September 2011

Woven unit-cell geometry functions are presented for a balanced plain weave fabric. Based on the functions, a 3D geometrical model applying to a meshing preprocessor for 3D finite element is proposed. The geometry model takes into account the existence of the space between tows, the undulation of the tow, and the actual tow cross-section shape. The internal geometry of model is from micrographs of sectioned laminates, which is helpful to define the accurate and actual 3D geometrical model. The section shape of the yarn remains unchanged along the trajectory. This model can be easily identified using three parameters measured on a real fabric. An accurate hexahedral mesh developed using these geometry model is presented. This is an important point for 3D finite element simulation of fabric model, which is a powerful method to investigate the mechanical behavior and also the composites made from it.
