What is Laid Scrim

Laid scrim is a low cost reinforcing fabric made from continuous filament yarn in an open mesh construction. It is used for handling and to strengthen thin prepreg plies in geometries requiring thin sections or change in contour.
The scrim is bonded to the prepreg by thermal decomposition or melt infiltration. The resulting component is dense and has high tensile strength.

Fiberglass is a strong, flexible material that can be used in a variety of applications. It is used in building structures, roofs, and insulation materials. It has excellent resistance to corrosion, heat, and chemicals. It is also available in a wide range of shapes and sizes.
Laid scrim is a cost-effective reinforcing fabric made by chemically bonding continuous filament yarn in an open mesh construction. It is commonly used to increase tear or puncture resistance, improve dimensional stability, and facilitate processing. It is often combined with functional binders to provide specific chemical or thermal properties, for increased moisture resistance, or for improved adhesion.

The use of polyester in Laid Scrim provides for a cost-effective and versatile material to help increase tensile strength, dimensional stability, and tear resistance in many products you see every day. This technology is used for a wide variety of applications in roofing, flooring, tapes, automotive, composites, hygiene, medical and packaging.
This non-woven fabric is made by a manufacturing process that chemically bonds the continuous filament yarns of the scrim. This produces a scrim that is much lighter than woven and knitted fabrics and can be shaped to meet specific design requirements.
In one exemplary embodiment, the dual or multilayer self-supporting scrim may be mechanically pleated into suitable geometrical configurations to form a filtration media element. The pleat tips are then pushed through a channel formed by top and bottom platens that are heated to 250deg F to 300deg F, which softens the thermoplastic latex binder of the Scrim at the pleat tips and causes the pleats to retain their geometry upon exiting the channel and cooling.
Aramid fibers are a group of synthetic fibres that offer a unique set of properties. Known commercially as Kevlar, Twaron and Nomex, they have superior strength and flexibility as well as good resistance to chemicals.
Laid scrims can be manufactured in a wide range of constructions and weaves. Depending on the application, these fabrics are either used to increase strength or to provide reinforcement for laminates. They can also help to improve dimensional stability, facilitate handling and act as carriers for adhesives.
The most common scrim is a simple side-by-side construction, where warp threads lie underneath the weft yarns. This type of scrim is easy to produce and offers excellent tensile strength and durability. It also has high resistance to abrasion and puncture. It can also be bonded to other materials, such as glass mat, synthetics or film. It is also able to resist a wide variety of temperatures and humidity levels, making it ideal for use in harsh environments.

Laid scrims are chemically bonded fabrics consisting of continuous filament yarn in an open mesh construction. These fabrics are used in many different applications to increase tear or puncture resistance and improve dimensional stability. They may also be used to provide heat or moisture resistance. Additionally, they can be used to add adhesive properties.
A laid scrim is a non-woven fabric composed of strands of polyethylene, polypropylene or mixtures thereof, polyester fibers, cellulose acetate fibers, nylon fibers and acrylonitrile and vinylchloride copolymer fibers. These fibers are bonded with a latex binder. The resulting product can be supplied either loomstate or impregnated.
