1. Characteristics of glass fiber direct roving

What is glass fiber direct roving? Glass fiber direct roving is a roving bundle twisted from continuous E glass fiber strands. It has excellent strength, chemical corrosion resistance and process adaptability. It is one of the basic raw materials for composite material reinforcement and is widely used in winding, pultrusion, weaving and other processes.The core characteristics are as follows:

Stable twist and uniform tension: the roving bundle structure is tight and does not break during operation.

Good wettability: compatible with a variety of thermosetting and thermoplastic resin systems.

Strong adaptability: can be applied to a variety of molding methods such as hand lay-up, winding, pultrusion, weaving, etc.

High tensile strength and good corrosion resistance: suitable for structural reinforcement in a variety of complex environments.

2. Advantages of glass fiber direct roving

Strong versatility: one roving for multiple uses, suitable for mainstream composite material molding processes.

High molding efficiency: stable roving bundle tension, good fluidity, and improved production efficiency.

Stable reinforcement performance: composite finished products have high strength and good fatigue resistance.

Environmentally friendly and harmless: does not contain asbestos or heavy metals, and meets the industry's environmental standards.

3. Typical application scenarios

Pipeline winding: such as oil and gas pipelines, high-voltage cable protection pipes, chemical anti-corrosion pipes.

Pultrusion products: such as fiberglass profiles, cable trays, door and window frames, subway guardrails.

Woven cloth base: Preparation of glass fiber woven cloth for ships, plates, composite shells, etc.

4. Purchase and use guide

Main parameter reference:

Fiber diameter: 13-24μm, selected according to customer needs.

Line density: Common specifications are 2400tex, 4800tex, 9600tex, and the selection is based on process and strength requirements.

Usage suggestions:

Check the neatness of the roving bundle before use to avoid knotting and breaking.

Avoid moisture and direct sunlight, and keep the storage environment ventilated and dry.

5. FAQ

What is the difference between direct roving and assembled roving?

Both are glass fiber raw yarns, but they are made in different ways and used in different ways. Direct roving is formed by directly merging raw yarn bundles, with a tighter structure and better wettability. It is often used in modern processes such as composite materials, molding, and injection. Assembled roving is first made into a single yarn and then twisted into multiple strands. It is more common in the production of traditional glass fiber cloth and fabrics.

Can direct roving be thermoplastic reinforced?

Of course. Many direct roving models are now specially designed for thermoplastic materials, such as PP, PA, PBT and other thermoplastic resins, as well as LFT, thermoplastic sheets and other application fields.

6. Summary

As the core reinforcing material in the composite material industry, glass fiber direct roving has been widely used in many fields such as pipelines, profiles, wind power, ships, and construction due to its excellent mechanical properties and processing adaptability. Reasonable selection, standardized storage and transportation, and efficient process matching will help companies significantly improve the performance and production efficiency of composite materials products.If you are looking for high-quality glass fiber direct roving, the hot-selling products in China are CPIC 469H, CYS-E310, etc. For more information or to obtain our glass fiber direct roving product information, please contact us via email annayu@169chem.net or phone 18909016373.
