From July 7 to 9, SAMPE China 2021—comprising the annual conference and the 16th International Exhibition on Advanced Composite Materials, Raw Materials, Tooling, and Engineering Applications—was held in Beijing. XTOP3D participated in the event with its proprietary 3D full-field strain measurement solution, comprehensively showcasing the company's capabilities in the field of mechanical property testing and evaluation for new materials.
With the rapid advancement of cutting-edge science and technology, performance requirements for materials are becoming increasingly stringent. Advanced composite materials serve as vital components supporting high-end manufacturing sectors—such as new energy, rail transit, automotive lightweighting, healthcare, intelligent equipment, and green construction—while driving technological progress in related industries and the transformation of the national economic structure.
Testing and evaluation span the entire lifecycle of material R&D, production, and application, serving as a foundational and critical link in the quality improvement and industrial upgrading of the materials sector. In 2018, the Ministry of Industry and Information Technology (MIIT) issued the *Implementation Plan for the Construction of a National Testing and Evaluation Platform for New Materials* to accelerate the development of such platforms; the initiative aims to overcome testing bottlenecks and resolve the dilemma where "available materials are difficult to use, while high-quality materials are avoided due to uncertainty." XTOP3D’s full-field strain measurement solution is designed for mechanical property testing in these platforms and laboratories, addressing the challenges associated with evaluating new materials and enabling advanced composite materials to support the innovative development of greener industries—characterized by lighter weight, greater energy efficiency, and enhanced environmental sustainability.
Aligned with the annual conference’s exhibition theme—"Advanced Composite Materials: Leading Innovation and Green Industrial Development"—XTOP3D meticulously prepared its showcase. The company demonstrated its technical capabilities through product demonstrations, brochures, technical briefings, and promotional videos, highlighting services such as mechanical property testing, structural strength validation, finite element analysis and optimization, non-destructive testing (NDT), and structural health monitoring for composite structures. XTOP3D’s booth attracted significant attention from exhibitors, guests, and visitors alike, with numerous renowned organizations expressing interest in potential collaborations.
Mechanical Property Testing of Composite Materials
The XTOP3D XTDIC 3D optical full-field strain measurement system supports the use of various camera configurations to measure 3D strain fields under complex operating conditions. Applications include high-temperature mechanical property testing, carbon fiber riveting strength testing, large-scale composite material testing, large-deformation tensile testing of rubber, and high-speed puncture testing of specialty materials. By analyzing full-field deformation during loading, the system enables a comprehensive assessment of the material's mechanical properties.

Micro-scale Deformation Testing
Testing the deformation of material surfaces at the micro-scale has long been a challenge in the industry. The XTDIC-micro microscopic strain measurement system seamlessly integrates optical microscopy with Digital Image Correlation (DIC) technology to meet the needs of deformation testing for materials at the millimeter scale. By overcoming the limitations of traditional measurement methods, it has become a powerful tool for deformation testing at the mesoscale.
