Composites worldwide fkom FRP Services The composites industry is now a global business, but any doubters looking for proof need look no further than FRPServices. The firm boasts a product distribution network across 80 countries covering every bet of reinforced plastics. Aman& Weaver spoke to some of the companies represented by FRP on their joint stand at this year’sJEC exhibition.
Over the last 20 years Osaka-based FRP Services has grown into a global distributor. It serves 80 countries from five warehouses in Singapore, the United Arab Emirates, the USA and The Netherlands as well as in Japan, and has a European office in Aixen-Provence, France.
The variety of products and services offered by FRP Services has grown as well and now covers the whole reinforced plastics in-
The firm started out as a distributor for Japanese companies and now represents 44 different Japanese firms with a spectrum of activities across the chemical and glass fibre fields. More recently it has supplemented its portfolio with Asian, European and American producers of a range of specialist products. Polyester production

manufactures carbon and aramid fibres and epoxy prepregs.
Grades produced include general purpose, isophthalic, bismaleimide and a neopentyl-glycol gel-coat. The company also makes resin for plywood, casting, roofing and artificial marble as well as for heat resistant and marine applications. A key selling point is the ability to make a resin to the customer’s specific requirements, says marketing manager Andy Tsai.
Reduced print-through in composite laminates is offered by the glass tissues and veils made by Regina. The firm is the sole Australian maker of glass tissues, where it has had a plant since 1963. It sells to Europe as well as South East Asia, Japan, Taiwan, Singapore, New Zealand and the United Arab Emirates.

He says that Weskor is less expensive than competitive core materials but offers superior properties. Important applications for the material include ski laminates and Westwind says that it is currently in negotiations with three ski manufacturers. Weskor combines the properties of both foam and honeycomb cores. The honeycomb structure stabilizes the foam eliminating the problem of shear. While the foam filling enables 100% bonding with the surface of the honeycomb. It also improves
An alternative to using a core material might be to use a 3-D space fabric, such as those produced by Vorwerk of Germany. The firm’s TechnoTex distance fabrics are made using velvet weaving technology. Pile fibres are integrated between two layers of fabric as the warp beam moves from one layer to the other. When the E-glass fabric is impregnated with resin by the moulder it gives a space fabric which can be used to make lightweight sandwich panels in one process from one material. The skins are integral to the core which provides excellent peel strength and laminate integrity. Space fabrics are particularly interesting in applications where there would be moulding or chamfering problems associated with using a foam core. The space fabric makes it easy to integrate load introduction points, says Ulrich Kbrber, apphcations engineer for TechnoTex, it merely needs to be down during weighted resin impregnation to stop the spacers expanding. Tank and lining manufacture is another major application for Vorwerk’s space fabrics. The structure of the fabric can be used to monitor leaks, either by installing a liquid indicator at the lowest point of the tank or by applying a positive pressure to the space and looking for a drop in pressure.
The non-crimped fibres in knitted fabrics offer strength advantages, says Advanced Textiles.

rently out for tender. Advanced Textiles Inc of Seguin, Texas, is also a weaver of composite reinforcement fabrics. But the firm believes that its knitted fabrics offer the best potential for future growth. Knitted fabrics are a growing area because of the high strength offered by the noncrimped fabrics in them, says Charles Pedersen of FRP Services. They also offer reduced weight and higher ultimate tensile strengths compared with woven fabrics. Applications for knitted fabrics include reinforced structures for boat hulls and decks, lightweight pultruded tailgates for trucks, high strength carbon fabrics for aircraft laminates, water and snow skis, chemical storage tanks and piping, and large corrosion-resistant industrial fan blades.
Andrew Lucas, Colan’s export manager, says that the firm’s fabrics are used for aerospace products as well as to make marine items such a special kayaks for white water rafting. A special wide woven fabric is also made for use in truck panels. In the future the firm is optimistic that it will gain substantial business supplying woven fabrics for an Australian Navy minehunter which is cur-

b Advanced Textiles manufactures both types of fabric at its Seguin plant. The standard product range includes more than 35 knitted fabrics and 20 standard woven fabrics. It can also custom design fabrics to optimize customers’ moulding operations in a range of fabrication technologies. The plant produces fabrics in a variety of fibres and orientations and can also stitch fabrics to various substrates and attach surface veil materials.
