In order to replace a conventional steel bogie to a composite one, in this study, a GFRP composite bogie frame has been designed and manufactured to be applied to the bogie of urban subway trains. To evaluate the structural behavior, the compositebogie frame was manufactured using the autoclave curing method and tested under the critical load
A study on evaluation of fatigue strength of a GFRP The fatigue strength and life of a GFRP composite bogie frame for urban subway trains were evaluated in this study. The GEP224 glass fabric/epoxy was selected as the structural material of a composite bogie frame to save its weight. In order to obtain the fatigue characteristics of the GEP224 glass/epoxy composite material, the tensioncompression fatigue test was done with three different stacking
GFRP Rebar:A Preferable Option for Construction. Contrary to steel, rebar made from GFRP composites has proven to be a much better option. The strength of composite materials gives the structure much needed support and protection against harsh weather conditions. An added bonus is the fact that GFRP composites are resistant to corrosion.
Composite Material and Rail TransitApplication- FRPThe advantages of composite materials are full. Lets look at the application areas of high-speed rail transportation. At present, composite materials are mainly used as non-structural parts materials such as interior decoration and body equipment.

The vice frame bears and transfers the forces and loads between the bogie and the vehicle body.The strength of the vice frame relates directly to the stability and smoothness of the vehicle. In this study, finite element analysis is utilized first to analyse the structural strength and fatigue life of the vice frame, and the recognize the weak parts of its structure in order to enhance its
Manufacturing and testing of a GFRP composite bogie frame Sep 19, 2013 · To replace a traditional steel bogie with a composite one, this study designed and manufactured a composite bogie frame made of glass fiber-reinforced plastics to be applied to the bogie of an urban subway train. To evaluate its structural behavior, the composite bogie frame was tested under critical load conditions encompassing vertical loads and a twisting load. The test
OPPORTUNITIES FOR THE USE OF COMPOSITE Composite materials are also known to have been applied to bogie design and manufacture. Glass fibre reinforced polymer (GFRP) composites have been used to lightweight certain bogie frames by up to one tonne , although it is worth noting some bogies already weigh less than one tonne . In
Nowadays, destructive bomb effects and terroristic attacks to buildings have become a challenge for structure engineers. Reinforcement of structures with composite materials has been extensively increased in recent decays, because of their individual and unique characteristics like high impact strength, flexibility, high-weight ratios, etc. The technique of wrapping concrete with CFRP/GFRP
Seismic retrofitting of reinforced concrete frame This paper presents a new type of structural bracing intended for seismic retrofitting use in framed structures. This special composite brace, termed glass-fiber-reinforced-polymer (GFRP)-tube-confined-concrete composite brace, is comprised of concrete confined by a GFRP tube and an inner steel core for energy dissipation. Together with a contribution from the GFRP-tube confined concrete, the
Structural performance of GFRP connectors in composite The main challenge from a structural point of view during the development of these innovative facade elements is ensuring that they will resist the anticipated loads, e.g. wind and self-weight, and transfer them to the main structural frame in different design situations without posing issues of safety, serviceability, durability and robustness.
