In-vitro MRI detectability of interbody test spacers made of carbon fibre-reinforced polymers, titanium and titanium-coated carbon fibre-reinforced polymers.

RETRACTED ARTICLE: Magnetic resonance imaging evaluation of intervertebral test spacers: an experimental comparison of magnesium versus titanium and carbon fiber reinforced polymers as biomaterials

INTRODUCTION Intervertebral spacers are made of different materials, which can affect the postfusion magnetic resonance imaging (MRI) scans. Susceptibility artifacts, especially for metallic implants, can decrease the image quality. This study aimed to determine whether magnesium as a lightweight and biocompatible metal is suitable as a biomaterial for spinal implants based on its MRI artifacti...

Introduction of Fibre-Reinforced Polymers − Polymers and Composites: Concepts, Properties and Processes

Fibre-reinforced polymer(FRP), also Fibre-reinforced plastic, is a composite material made of a polymer matrix reinforced with fibres. The fibres are usually glass, carbon, or aramid, al‐ though other fibres such as paper or wood or asbestos have been sometimes used. The poly‐ mer is usually an epoxy, vinylester or polyester thermosetting plastic, and phenol formaldehyde resins are still in use...

Influence of carbon fibre-reinforced polymers reinforcing on the seismic behaviour of timber-framed walls with fibre-plaster sheathing boards

This paper provides an experimental analysis of timber-framed walls, coated with carbon fibre-reinforced polymers (CFRP) strengthened fibre-plaster boards. The presented wall elements are usually used as main bearing capacity elements in the construction of prefabricated multi-level timber residential buildings. Since the tensile strength of fibre-plaster sheathing boards (FPB) is approximately...

Influence of Temperature and Moisture on the Compressive Strength of Carbon Fiber Reinforced Polymers

The effect of moisture absorption and high temperature on the compressive strength of unidirectional IM7/977-2 carbon/epoxy resins have been investigated experimentally. The specimens were divided into 4 groups, and tested under 4 different conditions by varying the testing temperature and moisture parameters. The fiber orientation selected were 0o, ±45o and 90o...
