Understanding Woven Roving Combo Mats
Woven roving combo mats are composed of two primary components: woven roving and chopped strand mats. The woven roving provides high tensile strength, while the chopped strands offer improved surface finish and flexibility. This combination is stitched together using polyester thread, resulting in a product that balances strength and ease of use.
Composition and Material Properties
The woven roving component typically ranges from 300 g/m² to 900 g/m², while the chopped strand mat can vary from 50 g/m² to 500 g/m². This flexibility in composition allows manufacturers to tailor mats to specific needs, whether for high-strength applications like boat building or lighter projects requiring quick laminate build-up.
Manufacturing Techniques
The production of woven roving combo mats involves advanced stitching techniques that ensure durability and consistency. High-strength polyester threads are used to stitch the layers together, which not only enhances the structural integrity of the mat but also ensures compatibility with various resin systems including unsaturated polyester, vinyl ester, and epoxy resins.
Applications of Woven Roving Combo Mats
Woven roving combo mats are widely used across various industries due to their adaptability. Here are some key applications:
Boat Building
One of the primary uses of woven roving combo mats is in the marine industry. Their high strength and lightweight properties make them ideal for constructing hulls and other structural components of boats. The combo mat’s quick laminate build-up capability is particularly advantageous for manufacturers looking to improve production efficiency.
Construction and Infrastructure
In construction, these mats are utilized for reinforcing structures, such as FRP tanks and cured-in-place pipe (CIPP) liners. The durability and chemical resistance of woven roving combo mats make them suitable for environments where traditional materials may fail.
Repair and Maintenance
Woven roving combo mats are also effective in repair applications. Their compatibility with various resin systems allows for quick and effective repairs, ensuring that structures maintain their integrity over time.
