Hired help for bespoke composite tests

“We have invested heavily in the latest materials testing equipment for our Honiton lab, but we have a regular requirement for NDT equipment and financially it makes sense to hire these instruments,” said Paul Yeo, MD of Composite Test & Evaluation.

With a background in testing for the helicopter industry, Yeo established the company around six years ago and has seen considerable growth over that time. “We provide consultancy and mechanical testing services for composites and non-metallic specimens, and have established a strong reputation in a variety of industry sectors including automotive, aerospace, construction and renewable energy.

“As a service provider, we rely on recommendations and referrals, and a high proportion of our income is from repeat business, so we focus heavily on the quality of our work; offering feedback and explanations in addition to test results.

“We provide a quick response to customer requests so our working relationship with Ashtead Technology has been mutually beneficial. This is because we have fast access to a wide range of technologies and by renting we only pay for them when we need them, which lowers costs for us and our clients.”

One of the bespoke testing services provided by Composite Test & Evaluation is ‘compression after impact’ testing – a procedure in which samples are subjected to impacts across a range of energy levels and subsequently assessed by non-destructive testing (NDT).

This assessment is undertaken with a hired DolphiCam; an ultrasonic array inspection system for the detection of flaws. Connected to a PC, tablet or laptop via a USB port, the DolphiCam creates a high resolution colour image of defects or damage in just a few seconds; providing a variable angle 3D representation of the inspection area.

One of the advantages of Dolphicam over other systems is the easy to use software that behaves like a smartphone app and requires very little training to operate. Combined with a touch-screen laptop, which is provided as part of the rental equipment, the system is incredibly quick to set up and start analysing defects in composites.

Following a brief familiarisation course, Yeo said: “The ease with which the DolphiCam can be operated makes this the ideal instrument for our application; we do not need to employ a highly qualified NDT engineer, yet we are creating very high quality reports.”
