Objective
Objectives and content
The introduction of plant fibre based composites as a new
group of materials and the steadily increasing
application of conventional fibre composites for high
strength engineering applications for pipes, storage
tanks and other high risk areas has introduced an
industrial demand for new, fast and reliable nondestructive evaluation techniques. From the scientific
point-of-view one innovative aspect is related to
developing inspection methodologies for plant fibre
composites, which due to e.g. very similar density
between fibres and matrix are difficult to inspect, by
ordinary techniques. From an industrial point-of-view,
the economic benefits of developing inspection
methodology for fibre composite pipes, tanks and their
welds are more important. Two complementary innovative
fast techniques are being developed in this project:
A low energy near real time X-radioscopy system,
comprising as an option a dual energy imaging module for
optimum contrast between fibres and matrix; and
A lock-in thermography system, optimised concerning
heat excitation procedure, heat source and excitation
frequency for an optimum performance on inspection of the
considered range of materials and geometries. These
developments are evaluated in the project for their
application with respect to the conventional fibre
composites and the thermoplastic welds, and for plant
fibre composites. In the latter case, since these
materials are little known (but very attractive for
environmental and strategic reasons), some effort is also
attributed in the project to provide further
understanding between the flaw population and the
strength of the product.
The opportunities connected with the project can be
divided into three categories:
A short term, involving the immediate application of
the developed techniques. For this, a market of between
20 and 40 MECU in 3 years has been envisaged by the
partners;
A medium term, involving the future industrial
application of the techniques and the results (e.g. on
defect characterisation and their consequences) for the
plant fibre based composites. The market for this range
of products may make up 50% of current glass fibre
composites in 7 to 10 years, amounting to about 5 x 109
kg/year;
A long term, where the benefits of improved product
quality owing to product control and regular inspection
results in a prolonged lifetime and lower risks of
failure.
An important part of the prototype systems to be
developed is the emphasis on the ability to derive
quantitative information. Quantitative procedures to be
developed includes a pseudo 3-D imaging technique for
lock-in thermography and an absorption based dual energy
imaging technique for determination of fibre to matrix
relations in composite pipes.
By the successful elaboration and characterisation of the
two prototype inspection systems, the possibility and
cost-benefit of merging these into one single system,
hosted by the same PC and making use of the same hardware
will be evaluated.
The project consortium includes a manufacturer of X-ray
detector units, a manufacturer of X-radioscopy and CT
equipment, a manufacturer of thermography equipment, an
engineering company (NDT), a supplier of plant fibre
composites and a manufacturer of conventional fibre
composite pipes and storage tanks. Two R&D organizations
are involved in the research.
The Brite-Euram areas covered by the proposal are 2.3 and
1.4.
