Fiber Reinforced Polymer (FRP)

Explore this topic

Fiber Reinforced Polymer (FRP) Systems, also known as fiber reinforced linings, are composite materials commonly used to reinforce infrastructure, including steel piping, in the oil and gas and other process industries. They are made of polymer matrices and reinforced with fibers.

FRP is frequently used to reinforce existing pipelines that have deteriorated over time; though they can also be used to correct design or construction errors in new pipelines. Of course, they can be used to reinforce other types of structures as well.

The materials used in creating FRP fibers are typically either glass, carbon, or aramid. Less common fibers used to make FRP include paper, wood, or asbestos. The polymer components of FRP are commonly made up of either epoxy, vinylester, or polyester thermosetting plastics, although sometimes phenol formaldehyde resins are used instead.

Articles about Fiber Reinforced Polymer (FRP)
September/October 2023 Inspectioneering Journal

A look at the dominant damage mechanisms experienced by FRP during service and several detection methods to identify inspection information for FFS assessment.

Authors: Geoff Clarkson
March/April 2021 Inspectioneering Journal

Globally accepted FFS procedures for non-metallic components, such as reinforced thermoplastic pipes, do not exist. There may be opportunity in adapting existing procedures for metallic components and their damage mechanisms to composite components.

Authors: Dr. Rob Kulka
January/February 2021 Inspectioneering Journal

Even with significant work to establish standards and codes for FRP vessel design, failures still occur, some of which could have been prevented or mitigated by following a systematic external inspection program.

Authors: Geoff Clarkson
March/April 2020 Inspectioneering Journal

This article describes the construction of corrosion-resistant fiber reinforced polymer (FRP), commonly used for pressure vessels and piping in the chemical processing industry, and the practices used for inspecting corrosion-resistant barriers.

Authors: Geoff Clarkson
July/August 2019 Inspectioneering Journal

This article is written to provide a brief case study of an acoustic emission test of an FRP storage tank. A method combining acoustic emission with ultrasonics is proposed to ensure reliable long term operation.
