Distinct Reinforcement Forms
Reinforcements are supplied by engineers working in the FRP pultruded grating manufacturer’s foundry in
distinct basic forms. This offers flexibility in cost, compatibility with resin system, strength, and process
requirements. All fiber reinforcements are derived as single filaments regardless of the final form.
Manufacturers form numerous filaments and gather them into a strand. They later apply a surface treatment
to facilitate processing, maintain integrity of the fiber, and offer compatibility with certain resin systems.
Once the surface treatment is given to the strands, manufacturers further process them into several forms of
reinforcements for use in molding FRP.
1.Continuous strand roving
This is the basic form of reinforcement that is supplied as untwisted strands wound for further processing.
Continuous strand roving is usually chopped for spray-up, perform or sheet molding compounds.
Woven roving is heavy, drapable fabric that is available in several thicknesses, widths, and weights. The cost of
woven roving is comparatively lesser than traditional woven fabric. It is used to offer high strength in huge
structural components like boat hulls and storage tanks. Woven roving form is used initially in hand lay-up
Woven fabrics are made from fiber yarns that are of a finer texture as compared to woven roving. Manufacturer
can avail them in a vast range of sizes and in weights from 2 ½ to 18 oz./sq.yd. Several strength orientations are
Reinforcing mat is held together using a resinous binder or mechanically stitched. Reinforcing mats are used for
medium strength FRP materials.
Veil or surfacing mat is a thin fiber mat designed with monofilament and is not considered a reinforcing material.
Its main goal is to provide a great surface finish due to its effectiveness in blocking out the fiber pattern of the
underlying fabric or mat.
Chopped fibers or strands are available in distinct lengths from 1/8” to 2” for blending with resins and additives.
Manufacturers can use them and prepare molding compounds for injection or compression molding and other
Several surface treatments are applied to ensure fine compatibility with distinct systems of resins.
You are now aware of the different reinforcement forms used by FRP Pultruded Grating manufacturers for
production of FRP composites. If you need more details on this subject, kindly contact the manufacturer today.
