and replaced [2]. Recently, fibre reinforced polymer (FRP) matrix composite systems have become an alternative solution for structure repair. The repair systems are typically made with aramid (AFRP), carbon (CFRP), glass (GRP) or polyester fibre reinforcement in a polyester, vinyl ester, epoxy or polyurethane matrix. Compared to a steel sleeve or replacement, composite repairs have the following advantages: a) Easier and quicker to apply, the repair can be completed when the pipe  【Get Price】

Vasitars Composite Pipeline Repair - Composite Pipes

Usually, traditional repair methods require that the corroded or damaged piping is taken offline while the affected pipe section is replaced or reinforced by external steel strengthening/sealing elements. A recent application of composites for the oil and gas industry involves the repair of corroded pipelines by external wrapping of FRP in the affected sections. Primary benefits associated with FRP overwrap repairs are a continuous fluid transmission while the repair is installed and the  【Get Price】

Fiber Reinforced Sleeves for Permanent Magnet Motors

Schunk sleeves made of fiber composite materials have been used successfully for more than 30 years. They are mainly used in the rotors of permanent magnet motors, where they prevent magnets from lifting at high speeds. Due to their higher strength and lower density, they offer many advantages compared to sleeves made of stainless steel. For example, there are no dimensional changes in the diameter with increased temperatures because the coefficient of expansion is almost  【Get Price】

Steel Fibres - Advantages and Disadvantages ? Canzac

When steel fibres are added to mortar, Portland cement concrete or refractory concrete, the flexural strength of the composite is increased from 25% to 100% - depending on the proportion of fibres added and the mix design. steel fibre technology actually transforms a brittle material into a more ductile one. Catastrophic failure of concrete is virtually eliminated because the fibres continue supporting the load after cracking occurs. And while measured rates of improvement vary, steel  【Get Price】
