Development of FRP Pultruded Profiles

by: jinjiudingfrp   Keywords: FRP, Pultruded, Profiles

The project on 'Development of FRP Pultruded Profiles' was launched under the Advanced Composites Mission of TIFAC in August 1998 in partnership with M/s. Sucro Filters Ltd., Pune with technology support from National Chemical Laboratory, Pune. Sucro Filters has been working on pultrusion process, pultruded profiles and development of pultrusion dies with the NCL since January, 1998.

NCL support towards pultrusion die design, optimization of process parameters, resin formulation, selection of catalyst combinations in the resin etc. helped achieve a high pultrusion speed of 1.0-1.5 m/min with improved curing. Flame retardancy characteristics as per UL94V0 was achieved using halogenated resin & ATH (aluminium trihydrate) combination in pultruded FRP profiles.

The pultruded profiles like I-beams, channels, angles, flat strips, notch bars for FRP grating , cable-trays & ladders and solid rods for electrical insulation, etc. developed under the project were tested for mechanical & physical properties. The properties compared very favourably with the internationally available products.
Pultrusion is the most cost-effective method for the production of fibre-reinforced composite structural profiles. It brings high performance composites down to commercial products such as light-weight corrosion free structures, electrical non-conductive systems, off-shore platforms and many other innovative new products.

 

 

Based on the success of initial pultrusion trials at NCL, an associate Company, M/s. D K Fibre Forms Ltd. (DKFFL), Pune was promoted by Sucro Filters towards diversifying into the business of pultruded products. D K Fibre Forms has already set up quite a sophisticated pultrusion equipment & stabilized the process. A tool room equipped with radial drilling machine, plano milling machine & surface grinding machine and allied testing facilities for fabrication of pultrusion dies has been created at Sucro Filters with the assistance from TIFAC.

Towards the market seeding for commercialisation of the pultruded product , the Company targeted three major segments viz. new projects, replacement market in industrial & non-industrial applications. The orders for gratings for Alfa Laval, High Explosives Factory, Thermax Ltd., Pudamjee Pulp & Paper Mills etc. and also for railway coach interiors for the Integral Coach Factory, Chennai have been executed. Various applications & usage of the product have been actively pursued and the product has been recognized by acclaimed consulting agencies such as Humphrey & Glasgow, Uhde, Tata, EIL, Bechtel etc. DKFFL has recently bagged an order for supplying cable trays, fittings & other accessories to M/s Dabhol Power Project (DPP) as per the specifications of M/s Bechtel International Inc., the prime consultant for DPP.

The amount of energy required for fabricating FRP composite materials for structural applications with respect to conventional materials such as steel & aluminium is lower and would work for its economic advantage in the end.

The FRP Pultruded grating is a kind of plank with interstice, made into “H”-section profiles and “T”- section profiles. They are used as bearing bar and connected by zigzag connection rod according. It has a lot of advantages, such as less weight and higher strength, antisepsis, antiskid, combating ageing, long usage lifetime, resisting plane and fragmentation. In its creation, fire is not used, and the FRP Pultruded is dielectric and is not electrostatic. At the same time, in real usage, it doesn’t produce scintilla for impact. It is convenient to incise and install, and it has higher comprehensive benefit.

   Pultruded FRP grating is widely used in operation platforms, equipment platforms, stair steps, ditch covers, walkways, filter plates and filler supports, etc. in petroleum, chemistry, power, offshore exploration, electroplating, watercraft, water and waste water treatment, paper production, brewery and pharmacy industries. They are the ideal bearing parts in corrosive environment.

Because FRP is a composite material, its properties to adapt to a wide range, so it's very broad prospects for market development. According to relevant statistics, at present developing countries in the world the type of glass steel products reached about 40,000 kinds. While countries are in accordance with national economic development, the development of the direction of their different focuses, but basically have been involved in various industrial sectors. China's steel industry through the glass 40 years of development, has also been in the national economy has achieved success in various areas of application, in economic development has played an important role.

FRP now the main application areas, roughly summarized as follows:
@ the construction industry: cooling towers, FRP doors and windows New, building structure, envelope, interior equipment and decorative pieces of glass, steel plate, wave tile, decorative panels, sanitary ware and the overall bathroom, sauna room, surfing the bathroom, construction template, store construction, as well as the utilization of solar energy devices and so on.


@ Chemistry and Chemical industry: corrosion-resistant pipes, storage tanks storage tanks, corrosion-resistant pumps and its accessories, corrosion-resistant valves, grilles, ventilation facilities, and sewage and wastewater treatment equipment and accessories and so on.

@ Cars and rail transport industries: Automotive shell and other parts, all plastic mini-cars, large passenger body shell, doors, inner panels, the main columns, floors, bottom beams, bumper, instrument panel, mini-vans, as well as fire tankers, refrigerated trucks, tractor cab and machinery enclosures, etc.; in railway transport, a train window frames, inside the top bending plate, roof water tanks, toilet floor, luggage cart doors, roof ventilators, refrigeration door , storage tanks, and some railway communication facilities, etc.; in highway construction, there are traffic signs, road signs, Geli Dun, highway guardrail and so on.


@ Boats and water transport industry: River packet boat, fishing boats and hovercraft, all kinds of yachts, rowing, high-speed boats, lifeboats, transport boats, as well as glass, steel drums and floating buoy mooring buoy and so on.


@ Electric Industrial and Communications Engineering: There interrupter devices, cable protection pipes, generator stator coils and the supporting ring and the cone shell, insulation pipe, insulation rod, motor retaining ring, high-voltage insulators, standard capacitor casing, motor cooling casing, Strong wind generators and other electrical equipment panels; distribution boxes and electrical panels, insulated shaft, glass, steel enclosures and other electrical equipment; printed circuit board, antenna, radome and other electronic engineering applications. In recent years, with the scientific and technological development, as well as the improvement of people's living standards, many civilian glass fiber reinforced plastic products has been developed, such as the number of urban sculpture, arts and crafts style, fast food furniture, motorcycle parts, glass fiber reinforced plastic flower pots, safety helmets, Senior play equipment, household appliances, shell, etc., have successfully been widely applied.
