Friction Experiments for Filament Winding Applications

Abstract

ABSTRACT:The design procedure of nongeodesic filament wound products requires well-determined values for the available friction situated between the applied roving and the supporting surface. In this paper, we propose a mandrel shape with a specially designed meridian profile that enables a linearly proportional relation between the feed eye carriage translation and the measured values for the coefficients of friction. As a result of this property, the optically or chronometrically obtained measurements can directly be translated into coefficients of friction. Additional features of this approach are the high accuracy, repeatability, low experimental costs, and simple machine control strategies. With the proposed mandrel, we performed several experiments corresponding to the variation of typical filament winding-related process parameters: fiber speed, roving tension, roving dimensions, wet versus dry winding, and surface quality of the mandrel. The results indicate that the surface quality of the mandrel and the type of winding process (wet vs. dry fibers) have a considerable influence on the obtained data. The influence of the fiber speed, roving tension, and fiber material on the other hand, is negligible.

Comparison between elastic properties of theoretical, computational method and experimental results for filament wound composite pipes

“…Based on this literature review, it is clear that although filament wound pipes have been studied extensively, these studies differ in terms of the raw materials, fiber orientation, or nature of the polymeric matrix considered [26][27][28][29][30][31][32][33][34][35][36].…”

Experimental investigation of friction between prepreg tape and compaction roller for prepreg tape hoop winding

“…6,7 For the friction between fiber and support surface, Koussios and Bergsma addressed a mandrel shape with a specially designed meridian profile for non-geodesic filament wound products and then the optically obtained measurements can be translated into the coefficient of friction. 8 Considering the lateral tow slippage on the surface of mandrel, Finkenwerder et al. illustrated the influences of geodesic and non-geodesic winding path on the tow’s tensile force.…”

Performance index optimization of pressure vessels manufactured by filament winding technology

“…Filament-wound pressure vessels represent the proper choice to obtain good mechanical properties and lightweight. [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22] The pressure vessel geometry is generally cylindrical and the wall is composed of a 'liner' and a 'shell.' The liner holds the gas and guards the shell from chemical attacks.…”
