Advanced Ultrasound-based cameras for 2D and 3D Inspection of Composite Materials

Advanced Ultrasound-based cameras for 2D and 3D Inspection of Composite Materials

Dolphitech AS provides advanced ultrasound-based cameras for 2D and 3D identification, inspection and analysis of defects in composite materials. The Company uses advanced technology developed by a team of experts in ultrasound, analogue and digital electronics.

DolphiCam is a mobile and ergonomic ultrasound camera system designed for NDT inspection of CFRP (Carbon Fiber Reinforced Plastics). The camera uses a unique dry-coupling transducer technology with high performance signaling electronics creating high-resolution 2D and 3D images of suspected damage areas to verify the status of the material. We have now released a new product, DolphiCam Research, which gives scientists access to advanced camera control features such as raw data sets for further material analysis and user defined pulses.

DolphiCam is a mobile and ergonomic ultrasound camera system designed for NDT inspection of CFRP (Carbon Fiber Reinforced Plastics) creating high-resolution 2D and 3D images of suspected damage areas. The camera supports A-, B- and C-scan images, supporting both Amplitude and Time-of-Flight.

Unlike Phased Array systems, our matrix transducer gives simple, high-resolution images without moving the transducer, or using an encoder. The silicone-based transducer pad allows dry coupling on painted or shiny surfaces, and water or contact gel can be used on rougher surfaces.

-High resolution images
-Dry and wet coupling
-2D and 3D images
-A-, B-, and C-scans
-Amplitude & Time of Flight
-Manual Stitching function
-Windows 7 or 8 compatible
-User defined pulses
-Raw data access

ASM / ASTM / ASME Books on Mechanical & Corrosion Engineering

 ASM / ASTM / ASME  Books on Mechanical & Corrosion Engineering
1.ASM Handbook Volume 08 : Mechanical Testing and Evaluation

By Howard Kuhn

Hard Cover, Pages: 1000

About this book

Complete new revision of ASM's standard reference book on the mechanical characteristics and testing of metals, plastics, ceramics, and composites.

KEY FEATURES: Describes the basics of mechanical behavior with in-depth coverage on testing methods for metals, plastics, ceramics and composites. Articles describe the purpose, equipment, fixturing, data evaluation, and typical applications for standard and emerging mechanical tests. Comparative mechanical properties and the mechanical characteristics of metals, plastics, and ceramics are included throughout for general reference. Updated references to ISO, ASTM, DIN, EN, JIS and other standards are also included throughout for metals, plastics, ceramics, and composites.

DESCRIPTION: This newly revised and comprehensive ASM Handbook contains over 50 all-new articles plus newly revised updates on standard test methods for tensile, compressive, shear, hardness, creep, fatigue, and fracture-toughness properties. Expanded coverage also includes new articles on surface wear testing, adhesion testing, nanomechanical testing, Hopkinson bar techniques, dynamic indentation testing, fatigue testing, residual-stress measurements, and extensive new coverage on the mechanical testing of engineering components such as gears, bearings, fasteners, adhesive-bonded joints, piping, and welds.
