FEM Study of the Strain Kinematics in the 3D Nanofibrous Structure Prepared by the Electrospinning Process

引用

Applied Mathematics 2013年第5期4卷 80-90页

作者： Michal Petru Ondrej Novak David Vejrych Petr Lepsik Institute for Nanomaterials Advanced Technologies and InovationTechnical University of LiberecLiberecCzech Republic department of nonwovens Technical University of LiberecLiberecCzech Republic department of Machine Elements and Mechanism Technical University of LiberecLiberecCzech Republic

Finite element model (FEM) was used for the study and description of the arising 3D nanofiber structure strain caused by the pressure of the flowing gas. Computer simulation using an adaptive networking through implicit FEM algorithm can be utilized for a significant improvement of the study of anisotropic strain in the deformed 3D nanostructure. The created model is based on the empirical Laplace-Poisson differential equation for the flow, where gas particles are moving with certain kinetic energy. The kinetic energy depends on the speed, time and temperature and affects the resulting strain of 3D nanofiber structure. The simulation results were compared to the results obtained from the image analysis of real samples and showed that this FEM model can determine individual phases of structure strain. The comparison shows that the developed FEM model can be an important tool in the study of the strain in the arising 3D nano- fiber structure and it can provide valuable information for optimization of 3D nanofiber structure production by the electrospinning process.

The Effect of Silane Treated Sugar Cane Bagasse on Mechanical, Thermal and Crystallization Studies of Recycled Polypropylene

引用

Materials Sciences and Applications 2015年第8期6卷 724-733页

作者： Tshwafo E. Motaung Linda Z. Linganiso Maya John Rajesh D. Anandjiwala CSIR Materials Science and Manufacturing Polymers and Composites Competence Area Nonwovens and Composites Research Group Port Elizabeth South Africa department of Textile Science Faculty of Science Nelson Mandela Metropolitan University Port Elizabeth South Africa

This article describes the results of an investigation on the influence of loading silane treated sugar cane bagasse (SB) on the morphology and properties of recycled polypropylene (rPP). The samples are prepared through melt extrusion followed by injection moulding. The Scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) results show that SB-rPP composites have a fairly strong interfacial interaction and a change in crystallization for the highest containing SB composite, however, some fibre pull-outs are observed as the SB content is increased. The interaction influences the thermal and mechanical properties of the samples in a complex way. There are strong indications of a stronger interfacial interaction on the highest containing SB composite, which is supposedly accountable for the increased crystallinity and melting temperature.

At present three kinds of material can be used to make geotubes: splitting film fibrillated splitting film and multifilament. The geotubes made of these materials have their advantages and disadvantages. In engineering application to know the rule of forces change is very important. Based on geometry way limit-filling height of geotubes is determined.

作者：柯勤飞 department of Textile Technology

The technical parameters and the structural factors of melt-blown nonwovens used as filteringmedium are analysed,the orientation of particles filtered in a filter is described,and the optimalparameters for air filtration are *** results are shown as follows:the ratio of tenacity oflongitudinal to cross direction has a close agreement with the random coefficient of fiber arrange-ment in practice;large particles are most likely trapped on the surface of a filter,and smaller parti-cles are filtered throughout the depth of a filter,and the deeper,the smaller;moreover,higher fil-tering efficiency and lower pressure drop can be effected through the optimization of parameters.
