Filament to mandrel gap analysis: Resulting gap from filament winding over a cone-cylinder transition mandrel (reference NMTP NO. 93838)
Abstract
The composites industry employs a method of high speed continuous reinforcement lay-down called filament winding. This is a process where resin impregnated tows, bundles of filament, are wound over a rotating mandrel. The tows, hereafter referred to as filament, are laid down over the rotating mandrel at a prescribed wind angle. Consider a cylindrical filament winding mandrel with conical features such that the filament is tangent to both the cylinder and the cone simultaneously. A gap is formed between the points of tangency. The gap distance measured along a line normal to the filament and intersecting the mandrel`s axis of rotation. The maximum distance occurs between the filament and a point on the intersection of the cylinder and the cone. The problems this paper addresses are: given a cylindrical filament winding mandrel with conical features, what is the gap size for a given wind angle; conversely what is the wind angle for a given gap size; and what does the geometry need to be in the mandrel transition area between the cylinder cone such that the filament remains in contact with the mandrel at all times?
