Roving is broadly defined as a long and narrow bundle of fiber. What is roving used for?
What is Fiberglass Roving?
Fiberglass roving is made of hundreds of tiny glass filaments. The roving is eventually reinforced with a chemical binding material to create a protected cohesive strand. The term “roving” can refer to the actual process of bundling such materials together, or the finished roll of strands.
Because woven textiles typically have much higher levels of strength than non-woven materials, fiberglass roving is often sold as woven roving. The process of weaving the glass fibers together by interlacing each strand provides both impact strength and flexibility to the end-product. Woven fiberglass is available in a wide variety of weaves, widths, weights, and finishes.
A few of the most sought-after characteristics of woven glass roving include:
- Impact strength through continuous filaments
- Ability to quickly add thickness and bulk
- Lightweight relative to other composite materials
- Suitable sizing for multiple resins including epoxy and unsaturated polyester
How is Woven Roving Used?
Because of its extreme properties of strength, fiberglass roving is ideal for applications in which material strength can be improved by layering. Because it is impact resistant, this kind of roving is often used alongside chopped strand-mat to construct large-sized objects like boats, pressure tanks, and even aircraft.
Woven fiberglass roving presents as a tape or a fibered textile and is usually sandwiched between fiberglass mats rather than used alone. It’s supremely well-suited for hand lay-up applications. Its addition in layers increases overall flexural and impact resistance without increasing weight or thickness. It’s also a highly economical choice for large-scale applications.
