Roving for Spray – Up

Spray – Up Roving is used in the spray-up process and is the most widely used reinforcement by definition for open mold production.

Spray Roving yarn is made up of small diameter fiberglass filaments that combine to form a bundle of fibers that are wound onto a dispenser. In the spray-up process, the roving yarn is connected to a spray gun that cuts the filaments into short lengths and deposits the fiber in a resin pattern for application to the surface of the mold.

The spray roving thread facilitates the rapid production of large parts such as auto parts for RVs, boat hulls, swimming pools, among others. It is the most widely used reinforcement in the pen mold process.

Single End Roving

Single end roving is the most widely used reinforcement in the pultrusion and filament winding processes and is the fiber used for the production of fabrics.

It is produced by pulling glass fibers directly from the furnace inlet applying different sizes upon cooling and winding them to form a set.

Due to its excellent strength, Direct Roving Wire is ideal for applications requiring high glass content such as pultrusion and filament winding. In addition to being used for woven roving, it is also used in other processes like open mold and infusion when configured into fabrics.

Continuous Filament Mat

Continuous Filament Mat (CFM) is a reinforcing mat composed of continuous fiber strands that are spun to produce a random fiber orientation and bulk for closed molding applications.

Continuous Filament Mat (also known as continuous strand mat), is a randomly orientated fiber that differs from chopped strand mat because of continuous long fibers rather than short
chopped fibers. Continuous filament mat is produced by dispensing molten glass strands directly onto a moving belt in a looping fashion. As the glass fiber cools and hardens and a binder is applied to hold the filaments in place. The mat is then trimmed and rolled. Continuous filament mat is most commonly used in closed molding applications such as, vacuum infusion processing, resin transfer molding, cold molding, and compression molding. With properties
similar to those of chopped strand mat, the bulk nature of CFM is advantageous in filling the mold cavity in closed molding processes.

Chopped Strand Mat

Fiberglass Mat is a commonly used material as a reinforcement solution. The mat is made of fiber that provides equal resistance in all its points and is used for manual processes (hand lay-up) and open mold. The mat is created through cuts made to the continuous roving filaments in dimensions of 1.5 – 3.0 inches and these are dispensed randomly to create a sheet or mat.

Due to its composition, the Fiberglass Mat offers an easy option to create complex shapes through polyester or vinyl ester resins. The product is sold in rolls of different weights and lengths.

Chopped Strands

El filamento cortado de fibra de vidrio es combinado con resinas termoplásticas para producir una gran variedad de productos finales.
Este tipo de material es usado para procesos de sofisticación altos como la inyección de moldeo a alta velocidad. La combinación de la presión utilizando la técnica de inyección
en el moldeo con el uso de metales da la habilidad de poder producir piezas complejas en ciclos de tiempo menores.

Processes: Injection, compression, extrusion. ​

Combo MAT

Combo Mat, also called Woven Roving, is a combination of Woven Roving and Chopped fiberglass. The combination is stitched through a high strength polyester to ensure appropriate strength of the roll. The reason for combining these products is the added strength and resistance in the
manufacturing of end products.

It is commonly used in molding compressing, pultrusion, hand lay-up, RTM, vacuum infusion and filament winding processes for complex shapes that vary in size.

Stitched MAT

Woven Roving

Stitched Fiberglass Fabrics are ideally suited for selective reinforcement. Fiberglass is bundled and stitched together, rather than woven, so there is no crimp in the yarn. As a result, these reinforcements offer optimized directional strength for their finished composite parts. For this reason, they are popular in the wind energy industry.

These fabrics are ideal for wet lay-up and the infusion process, where fast wet-out and strength control are key—they’re meant to be used with resins to create hard, composite parts and are compatible with polyester, vinyl ester, and epoxy.

Woven Roving is used in open mold lamination processes where joint lamination is required.

Woven Roving is composed of Direct Roving Yarn that is woven in bundles in a similar way to textiles. This material is one of the most widely used in the open mold process in
conjunction with the Spray Roving Thread or the Fiberglass Mat. It is produced in a variety of weights and widths and can be customized so that the fabric is directed to a specific area.
Woven Roving is highly customizable and is used to create complex shapes.

Knitted Fabrics

Surface Veils

Fiberglass knitted reinforcements offer fiber customization and design flexibility to increase part strength and durability.

Fabrics can be produced in a Unidirectional or Bidirectional manner. These are made in multiple layers that are sewn together to hold the fibers together. The fabric that is created
is then cut and rolled to create products of different orientations, volumes and weights.

The use of these Fabrics allows flexibility in laminate design and Fabrics of different composites and directions can be created. It is a product that has a common use in many industries where a specific reinforcement is required in lamination.

Fiberglass or polyester veils are lightweight reinforcements made of fibers that are randomly dispersed in a thin sheet. These thin sheets or mats are used to improve the surface of products made in different processes such as pultrusion or open mold. They are commonly used in corrosion products so that the surface has a better performance. They are produced in different widths and thicknesses to meet specific laminate needs.
