Cotton flock is an innovative, milled form of cotton used as a filler and reinforcement fiber in adhesives, epoxy resins, cosmetics, and other applications. Those offered by R&G Faserverbundwerkstoffe GmbH (R&G) are white flocks of approx. 350 µm fibre length (typical 150–500 µm), 10–25 µm fibre width  (1–3 Denier), 1.5 g/cm³ specific gravity and tensile strength: up to 120,000 psi (ca. 800 N/mm²). Melting characteristics char at 250 °F (120 °C), decompose at: 300 °F (150 °C), insoluble in Acetone, DMF or 40 % NaOH, water uptake: approx. 0.3 g per g cotton flocks. R&G cotton flocks can be used for enhanced dimensional stability in moulded products, increased impact and abrasion resistance. They are low cost, low density (4.5 litre Cotton flocks = 1 kg (0.22 g/cm³), and feature good adhesion to epoxy, polyester, and polyurethane resins as well as to rubber compounds. They are  resistant to many chemicals and alkalines. Application(s): manufacture of light, non-draining adhesives, pourable moulding compound and coupler coatings for mould construction, using a mixture of 50 volume percent glass fiber cuttings and 50 volume percent cotton flocks.  Cotton flocks are not dangerous or a substance or mixture within the meaning of EU REACH Regulation for dangerous substances and mixtures.

Glass fiber chips are used in combination with cotton flakes for coupling layers in mold making. R&G offers chopped glass fibre strands of 3 mm length (± 5 mm) ideal for polyester resins due to the coating, and well suited for epoxy resins. Applications: Fibre pastes and moulding compounds, synthetic plasters, putties, adhesives, corrosion protection coats, and asbestos substitutes. In the case of coupling, layers to fill and back up edges and embed alignment dowels and screw unions in-mould construction, a mixture of 50 % vol. chopped glass fiber and 50 % vol. cotton flock is mostly used. Also available are milled glass fibers of 0.2 mm length for epoxy, polyester and vinyl ester resins. Applications: Fibre pastes and moulding compounds, synthetic plasters, putties, adhesives, corrosion protection coats and asbestos substitutes.

TRIATIC INCORPORATED manufactures diamond and CBN (*) electroplated wheels, tools and other products for composite applications. They can be used for for applications in composites, fiberglass, ceramics, and other hard, abrasive materials. 

TRIATIC Diamond Countersinks are offered in various diameters and angles with or without slots and pilots, straight shanks or threaded shanks. The diamond coating is extremely tough and durable resulting in a tool with long life, reducing tool changes and unnecessary downtime. 

Their electroplated Diamond Coated Router Bits are available in a variety of sizes, with flat or round ends, with or without slots and coolant holes. The flat face is ideal for routing, slotting and trimming composites and other hard abrasive materials. The round end tools can be used to drill and form shapes. Slots enable quicker removal rates and improved clearance for deeper grinding. Coolant holes can be added for through coolant on the end of the tool and side ports.

TRIATIC also offers Diamond Saws, Circular, Hole & Jig. Their Saw Blades electroplated with 40/50 grit diamond are ideal for cutting off or slotting fiberglass and other fiber reinforced plastic and composite materials and alumina. Diamond hole saws cut more accurately, leave a smoother finish, and and last up to twice as long as carbide-grit-coated teeth. Electroplated diamond saw blades are for use on reinforced plastic, composites, stone, brick, and other abrasive materials with high silicon content. TRIATIC diamond saw blades are available with or without slots. Depending on the material, slots can help keep the diamond section free of loading, keeping the blade free cutting and cool. The diamond hole saws are unmounted but arbors are available if necessary.

(*) Diamond and Cubic Boron Nitride (CBN) are both extensively used materials in tooling. Both are extremely hard. Diamond is a crystalline form of carbon. CBN doesn't exist in nature and is synthesized from boron and nitrogen. Generally, diamond is preferred for shaping extremely hard workpiece materials such as ceramics, carbides, stone and glass. CBN is better suited for applications generating high temperatures. TRIATIC diamond tools can be used with fiberglass, carbon, FRP, ceramics, carbide, quartz, marble/granite and other non-ferrous abrasion-resistant materials. CBN can be used with high speed tool steels, die steels, harden carbon steels, monel, inconel, rene, waspalloy and other hard ferrous superalloys.

(**) The abbreviation OAL in different TRIATIC parts means Overall all Length.

Fabric-based composites are used considerably for applications in many different industriea including  aerospace, defense, automotive, marine, construction  and others. Depending on the appllication, the composite materials  and therefore the fabrics used for their production possess, are in most cases required to feature high durability and strength, light weight, and a meaningful cost for replacement of steel or other materials in different uses.

Different fabrics used for composite laminations come in different types such as knitted , woven, and nonwoven with woven fabrics often used as reinforcement materials. Textile-reinforced composite materials are generally lower priced and more widely available as they are increasingly being produced via automated rather than manual methods. Their textile fabrics are pre-formed in terms of weaving, knitting, braiding, stitching, nonwoven, and so on. The composition and structure of selected fabrics for reinforcement plays a significant role for achieving the expected performance characteristics from composites. 

Extending our product portfolio we offer a wide selection of reinforcement fabrics for the composites industry, including carbon fiber, fiberglass, and Kevlar®. Sourced by quality manufacturers or their distributors they come in in various weights and weaves, different widths (usually 38", 50" and 60"),  in rolls with cut to length capability in yards (YD) or packages of 1,3 or 5 yards. Some of our commonly demanded reinforcement fabrics include fiberglass fabrics featuring excellent strength, durability, and affordability, carbon fiber fabrics exhibiting high strength-to-weight ratio and excellent stiffness and DUPONT KEVLAR® brand aramid fabrics with their exceptional strength and resistance to impact making them a preferred choice in aerospace, and industrial applications requiring high tensile strength and toughness. Hybrid fabrics are also offered combining different types of fibers to achieve a balance between strength, stiffness, and cost.
