CHOPPED STRAND MAT

A chopped strand reinforcing material composed of chopped fiberglass of various lengths randomly dispersed to provide equal distribution in all directions, held together by a resin soluble binder. Chopped strand mat is commonly used in laminates due to ease of wet out, the good bond provided between layers of woven roving or cloth and is comparatively low in cost. Chopped strand mat is categorized by weight per square foot, has two feathered edges and is sold by the running yard or in bulk by the kilogram in full rolls. Please contact us for a quote on full rolls.

E-GLASS CLOTH

E-Glass cloth is woven from fine yarns of twist and ply construction with the actual glass being a lime-alumina borosilicate glass of low alkali content. This glass composition offers ample flexural and tensile strengths, high chemical stability and high moisture resistance.
The cloth weave allows it to conform to curved surfaces with minimum fitting. E-Glass cloth if categorized by weight per square yard and is sold by the running yard. An E-Glass cloth tape with finished edges is also available and is sold by the running yard of in bulk by the 50 yard roll.

WOVEN ROVING

Woven Roving is strands of glass fiber grouped together to form a twisted yarn. The roving is then woven into a coarse, square, lattice-type open weave to form the material. Woven roving provides great tensile and flexural strengths and a fast laminate buildup at a reasonable cost. It is more difficult to wet out than chopped strand mat or cloth however, and because of the coarse weave, it is not used where surface appearance is important. A layer of chopped strand mat is used between each layer of roving to fill the coarse weave when more than one layer is required. Woven roving is categorized by weight per sq. yd. and is sold by the running yard or in bulk by the kilogram.

SURFACE MAT

Surface mat is manufactured similar in appearance to the chopped strand mat but is much finer. it is composed of fine fiberglass strands of various lengths randomly dispersed in all directions held together by a resin soluble binder. This material is used to provide a resin-rich layer in liquid or chemical holding tanks, or as a reinforcement for layers of gelcoat. This material is sold by the running yard or in bulk by the 250 meter roll.

NEMPC

NEMPC or Knytex is a fiberglass composite composed of 17 oz. biaxial (± 45deg) unwoven roving stitched fabric incorporating a 3/4 oz. chopped strand mat stitched to one side of the fabric. NEMPC is used where optimum strength and stiffness, particularly in corners and angles, is critical. The material is categorized by weight per sq. yd. (17.08 oz.) and is sold by the running yard or in bulk by the kilogram. Also available is a 1200 EBX ± 45 deg with no mat on the back.

S-GLASS CLOTH

S-Glass Cloth is manufactured similarly to E-Glass Cloth, but with a different sizing (coating). Thus, S-Glass Cloth is stronger and tougher that E-Glass Cloth and has 20% greater tensile strength. S-Glass Cloth provides a premium multi-stage finish and has the highest impact strength of all fiberglass materials. This material is categorized by weight per sq. yd. and is sold by the running yard or in bulk by the 125 yard roll.

CARBON FIBER

Carbon Fiber is a graphite fabric especially designed for use in laminates which have critical requirements for maximum stiffness, extremely high tensile (3 times that of steel) and comprehensive (5 times that of steel) strengths, with low weight. Its main function is local reinforcement to improve the strength to weight ratio of highly stressed parts. Carbon fiber is weak in shear strength and impact resistance and should be shielded from abrasion with fiberglass or other materials, such as Kevlar®. This material is categorized by weight per sq. yd. and is sold by the running yard.

KEVLAR 49®

Kevlar® is a high strength (5 times that of steel), high modulus (75% of carbon fiber) aramid fiber. Aramid is technically an aromatic polyamide, which is a complex hydrocarbon and a distant cousin of nylon. Kevlar® is the most impact resistant fiber on the market, also exhibits the highest tensile strength and highest resistance to damage, vibration and crack propagation. However, Kevlar® has very low compressive strength, so it is recommended that laminates carrying bending or compression loads have carbon fiber incorporated into the laminate to provide adequate stiffness. Kevlar® is also hygroscopic, ultra  violet sensitive and un-sandable, thus it is not recommended as a sheathing or outer ply of the laminate. Kevlar® is categorized by weight per sq. yd., available in a cloth weave and sold by the running yard.
