... Abstract This chapter outlines a methodology for the design of cylindrical pressure vessels, with emphasis on the establishment of winding patterns and the interaction between the real fiber bed geometry (finite roving dimensions) and the theoretical one. To highlight the materials-shape...

... associated with glass fibers that refers to a bundle or group of untwisted filaments. Continuous strand rovings provide good overall processing characteristics through fast wet-out (penetration of resin into the strand), even tension, and abrasion resistance during processing. They can be cut cleanly...

The reinforcement is usually a fiber or a particulate. Particulate composites have dimensions that are approximately equal...

... Spray-Up Spray-up is a low- to medium-volume, open-mold method similar to hand lay-up in its suitability for simple medium to large part sizes. However, greater shape complexity is possible with spray-up than with hand lay-up. Continuous-strand glass roving is fed through a combination chopper...

.... For example, strand tensile strength tests, periodically performed on incoming roving, provide a record of roving quality that may be important if anomalies develop in subsequent processing or product performance. Reference 8.8 also provides a comprehensive list of tests to evaluate reinforcement fibers...

..., maraging steels, forgings, and welding operations involve considerable expense with long lead times. On the other hand, fiberglass roving and the resin components are inexpensive. Some prepreg roving systems that are required by specifications can be relatively expensive; however, wet winding with resins...

E-glass is the most prevalent material, but S-2 glass, carbon, or aramid can be used where the improved properties justify the higher costs. Heavy glass woven rovings (500 g/m 2 ) can...

... monofilaments are sometimes used to reinforce structures, such as pressure vessels, but more frequently the reinforcement is in the form of yarn (a twisted bundle of filaments) or roving (a parallel bundle of filaments). Roving is used in unidirectional prepreg tape, whereas yarn is used in the weaving...
