Distributed fibre optic systems allow to get information of the local strain all along the optical
fibre. Advanced systems may get strains readings with a spatial resolution of a few mm, and …

Two approaches may be followed to obtain damage information from strain measurements:
1) To use multiple sensing points, and to reduce the huge amount of information by pattern …

Delamination is the most characteristic damage found in composite materials. Low velocity
impacts may lead to delamination onset, likely to occur during manufacturing processes or in …

Composite materials are vulnerable to damage, and this can result in conservatism in
design and increased maintenance costs. One way of reducing these costs is by integrating …

Structurally integrated fiber optic sensors hold the promise of improved quality control of
composites and “real-time, in-service” monitoring of the loads to which they are subjected …

This paper presents the application of distributed fiber optic strain sensing to commercial
aircraft composite fuselage panels for load monitoring and impact detection. This work is …

The detection of delamination damage is important in ensuring the safety of composite
structures. In this paper, a novel approach for delamination detection is described. The new …

In this paper, we describe a novel approach for delamination detection, which involves (1)
the application of a moving load on the composite member, and (2) measurement of total …

Optical fiber sensor systems have been recently used for, health monitoring of fiber
reinforced plastic (FRP) composite laminate structures. However, the diameter of optical …

Abstract Structural Health Monitoring Systems for the aircraft structures are intended to
detect the location and size of the damage with minimum downtime of the aircraft. As the …
