Fiber glass Roving

Fiberglass Roving

Fiberglass Roving is a bundle of continuous glass fiber filaments gathered without twist. It's a raw reinforcement material used in various composite manufacturing processes, especially where strength, volume, and resin compatibility are essential.

Types of Fiberglass Roving:

1. Direct Roving:

Drawn directly from bushings

Uniform, suitable for filament winding, pultrusion, and weaving

2. Assembled Roving (Multi-End Roving):

Several single-end rovings assembled together

Common in spray-up, hand lay-up and molding

Key Features:

High tensile strength and impact resistance

Excellent resin impregnation (polyester, epoxy, vinyl ester)

Good dimensional stability

Resistant to moisture, alkali, and corrosion

Lightweight and easy to process

Common Uses of Fiberglass Roving:

1. Filament Winding

For pipes, pressure vessels, gas cylinders, and storage tanks

2. Pultrusion

For making GFRP rebars, rods, channels, cable trays, and window profiles

3. Weaving

Woven into fiberglass fabrics like woven roving or multi-axial cloth

4. Spray-Up & Hand Lay-Up

Used in boat hulls, automotive parts, water tanks, bathtubs

5. Sheet Molding Compound (SMC) & Bulk Molding Compound (BMC)

Cut into chopped strands and mixed with resin for molded parts
