Comparative analysis of failure detection methods of composites materials’ systems

Abstract

This paper presents a review and analysis of current non-destructive failure detection methods of composite materials and a brief outline of the build of a bamboo bicycle which has been used as a development platform and test bed for the initial development of a novel and practical nondestructive failure detection solution, which has future compatibility for carbon-fibre (CF)-based bicycles. The paper begins by presenting the current market condition of composite materials and in particular, CF and CF-reinforced plastic, and then follows onto failure modes and proceeds to investigate a comprehensive range of failure detection methods.

A Brief Review on NDT&E Methods For Structural Aircraft Components

“…Thickness changes or flaws in the test element influence the flow of eddy currents and change the impedance of the coil [10,13]. Eddy current testing is particularly well-suited for detection of service-induced cracks [10], but also corrosion, surface breakings [3,10], missing carbon fibre bundles [13], porosity, voids and foreign inclusions [20]. The limitations of this qualitative method include the limited penetration depth and the undetectability of the damage parallel to the scan direction.…”

“…The limitations of this qualitative method include the limited penetration depth and the undetectability of the damage parallel to the scan direction. Moreover, only electrically conductive materials can be inspected [3].…”

From Thermal Inspection to Updating a Numerical Model of a Race Bicycle: Comparison with Structural Dynamics Approach

“…High-performance carbon fiber bicycle frames are strong and lightweight. However, they are susceptible to damage caused by low-energy impact loading, which have many possible causes: small stones can be projected by nearby cars or the front wheel of the bicycle, the bicycle may fall and hit the ground, and defects can occur during manufacturing [12,13]. In addition, material thickness inconsistency can occur during manufacturing and cause false positive defect hits.…”

Damage Detection and Critical Failure Prevention of Composites

“…Failure detection methods of carbon composite material systems are currently the subject of much research effort in the composite material community at large; see, for example [1][2][3][4], using a variety of failure detection methods and control algorithms. For enhanced reliability, early failure detection methods with critical failure prevention are preferable.…”

“…The amount of energy transmitted or received and the time the energy received is analysed to determine the presence of flaws [13]. Dye penetrant method [4] can be used to detect the materials surface defects, but as it can only reveal surface defects and does not give details of depth of defects, it can also be difficult to test coarse surfaces. Pulse thermography [14] is an advanced non-destructive testing method, in this method thermal imaging cameras are used to detect material failures [15].…”
