Overview
The Hengyi HY-3080YUJMM is a high-precision electromechanical universal testing machine engineered specifically for mechanical characterization of porous ceramics and ceramic matrix composites (CMCs) under elevated temperature conditions. Designed with a robust龙门 (gantry) architecture, it integrates high-stiffness load frames, servo-controlled actuation, and real-time closed-loop feedback to deliver stable, repeatable force and displacement control across demanding thermomechanical test protocols. Unlike standard ambient-temperature testers, the HY-3080YUJMM is structurally reinforced and thermally stabilized to interface seamlessly with external high-temperature furnaces (up to 1600 °C, furnace not included), enabling uniaxial tensile, compressive, flexural, and shear testing per ASTM C1211, ISO 14601, and JIS R1605 standards. Its dual-sensor architecture supports simultaneous high-fidelity measurement of axial load, crosshead displacement, and extensometer-derived strain—critical for accurate determination of elastic modulus, Poisson’s ratio, fracture strength, and post-yield behavior in brittle and quasi-ductile ceramic systems.
Key Features
- Gantry-style frame with 210 kg mass and rigid aluminum-steel hybrid construction for minimal thermal drift and vibration damping during high-temperature operation
- 30 kN load cell calibrated to ≤0.5 accuracy class (per ISO 7500-1), with internal resolution of ±500,000 digital counts and no range-switching required
- Wide dynamic speed range (0.001–500 mm/min), digitally regulated to ±0.5% accuracy; supports creep, stress-relaxation, and cyclic loading profiles
- Programmable control modes: load-, displacement-, strain-, and stress-rate control, each with configurable ramp-hold-step sequences
- Dual-limit safety system: hardware-based electronic travel limits plus software-defined overload cutoff (10% above full scale)
- Intelligent self-diagnostic firmware that continuously monitors drive current, encoder feedback, amplifier voltage, and sensor integrity—triggering immediate safe-stop on anomaly detection
- Modular fixture interface compatible with ISO 26203-compliant grips, including high-temperature tensile jaws, compression platens, three-point bend fixtures, and interlaminar shear test tooling
Sample Compatibility & Compliance
The HY-3080YUJMM accommodates specimens up to 380 mm wide and 800 mm tall, supporting standardized ceramic bars (ASTM C1161), disc-shaped samples (ISO 6872), and custom CMC laminates. When paired with certified high-temperature furnaces and vacuum or inert-gas environments, it enables compliant execution of ASTM C1358 (tensile strength of refractory ceramics), ASTM C1424 (compressive strength at elevated temperature), and ISO 14601 (flexural strength of advanced ceramics). All control logic and data acquisition meet GLP requirements, with optional 21 CFR Part 11-compliant audit trail logging available via HENGYITEST™ software configuration. Traceable calibration certificates (NIST-traceable load cells and extensometers) are provided with each system shipment.
Software & Data Management
HENGYITEST™ v5.x is a Windows-based, multi-threaded test platform offering full IEC 61508-aligned determinism. It acquires synchronized signals from load, displacement, and strain channels at up to 1 kHz sampling rate, storing raw data in HDF5 format with embedded metadata (operator ID, environmental conditions, calibration timestamps). Users configure test methods using drag-and-drop sequence editors, define pass/fail criteria against ISO 5893 thresholds, and generate PDF reports compliant with ISO/IEC 17025 documentation requirements. Curve analysis includes real-time overlay of multiple specimens, local zoom of stress–strain inflection points, feature-point annotation (yield onset, fracture point), and replay-mode visualization of deformation history. Export options include CSV, MATLAB .mat, and XML for LIMS integration.
Applications
- Mechanical screening of SiC/SiC, Al₂O₃-ZrO₂, and porous alumina scaffolds for biomedical implants
- Thermo-mechanical fatigue assessment of aerospace-grade CMCs under simulated turbine inlet conditions
- Interfacial shear strength evaluation of fiber-reinforced ceramic composites using Iosipescu or rail shear fixtures
- Creep rupture testing of porous thermal barrier coatings (TBCs) at 1200 °C under constant load
- Fracture toughness quantification (KIC) via single-edge notched beam (SENB) bending per ASTM E1820
- Quality assurance testing of sintered ceramic filters used in molten metal filtration systems
FAQ
Does the HY-3080YUJMM include a high-temperature furnace?
No—the furnace is a separate subsystem. The machine is designed to integrate with third-party high-temperature chambers (e.g., Carbolite Gero, Lindberg/Blue M) via mechanical mounting interfaces and analog/digital I/O synchronization.
Can the system perform ASTM E8/E21-compliant tensile tests on metallic specimens?
Yes—when configured with room-temperature grips and extensometry, it meets ASTM E8 (tensile properties of metals) and E21 (elevated temperature tension tests) requirements up to 30 kN and 1000 °C.
Is remote monitoring and control supported?
Yes—via optional Ethernet TCP/IP module and HENGYITEST™ Remote Server, enabling secure web-based access to live curves, test queue management, and alarm notifications.
What calibration documentation is supplied?
Each unit ships with factory calibration certificates traceable to CNAS-accredited laboratories, covering load cell, displacement transducer, and strain amplifier performance across full operating range.
Are custom fixture designs available?
Yes—Hengyi’s application engineering team provides CAD-supported design and validation of application-specific fixtures, including high-temperature collet grips and miniature specimen holders for micro-ceramic testing.
