Filament winding is a fabrication technique mainly used for manufacturing open (cylinders) or closed end structures (pressure vessels or tanks). This process involves winding filaments under tension over a rotating mandrel. The mandrel rotates around the spindle (Axis 1 or X: Spindle) while a delivery eye on a carriage (Axis 2 or Y: Horizontal) traverses horizontally in line with the axis of the rotating mandrel, laying down fibers in the desired pattern or angle. The most common filaments are glass or carbon and are impregnated in a bath with resin as they are wound onto the mandrel. Once the mandrel is completely covered to the desired thickness, the resin is cured. Depending on the resin system and its cure characteristics, often the rotating mandrel is placed in an oven or placed under radiant heaters until the part is cured. Once the resin has cured, the mandrel is removed or extracted, leaving the hollow final product. For some products such as gas bottles, the 'mandrel' is a permanent part of the finished product forming a liner to prevent gas leakage or as a barrier to protect the composite from the fluid to be stored.

A method of making a cylindrical pressure vessel (11) with a large diameter port in its sidewall includes the step of providing a mandrel (23) of desired diameter and filament winding upon the same. After winding one overall innermost layer, an annular reinforcement belt (16) is helically wound atop a defined region using a band (60) of resin impregnated parallel strands (39) under tension. The annular belt (16) is then itself helically overwound with the resin impregnated parallel strands of filamentary material under tension to provide two complete outer layers. After curing and removal from the mandrel (23) at least one aperture (71) is cut in the sidewall within the reinforcement belt (16) and a side port fitting (75) is installed in the aperture (71).

The invention discloses a building method for taper-changeable composite fiber winding adhesive layer models. The building method for the taper-changeable composite fiber winding adhesive layer models is a new method for building three-dimensional solid models of composite fiber winding adhesive layers in virtual three-dimensional environments by a modularized program drive method; according to a winding process of composite fiber winding products, three-dimensional space coordinate parameters of positioning control points on the fiber winding adhesive layers are calculated according to a normalized curvilinear equation, and modeling is realized by combining a three-dimensional design environment characteristic operation method; the problems of coordinate shifting of the positioning control points of the adhesive layers and segmental splicing of space curves both caused at spring layer / striding ring positions by composite fibers during simulation of the composite fiber winding adhesive layers are solved. The building method can build the composite fiber winding adhesive layer models with any filament winding lengths, and the models have high similarity to actual composite fiber winding adhesive layer products; the three-dimensional composite fiber winding adhesive layer models have wide range of adaptability to taper of winding mandrel bodies and high dimensional accuracy.
