Hengyi HY-3080MNRTT High-Temperature Tensile Testing Machine for Ceramic Matrix Composites

Overview

The Hengyi HY-3080MNRTT is a precision-engineered electromechanical universal testing machine specifically designed for high-temperature tensile characterization of advanced ceramic matrix composites (CMCs), oxide/oxide systems, silicon carbide-based materials, and other refractory ceramics. It operates on the principle of controlled axial force application under elevated thermal conditions—typically integrated with high-temperature furnaces (up to 1600 °C, furnace optional and separately configured) to enable in-situ mechanical evaluation across service-relevant temperature regimes. The system complies with fundamental mechanical test architecture defined in ISO 527, ASTM E8/E21, and ISO 6892-2 for elevated-temperature tensile testing. Its rigid龙门 (gantry-type) structural design ensures minimal frame deflection (<0.05 mm under 30 kN load), critical for accurate modulus and yield point determination in brittle, low-ductility ceramic systems.

Key Features

• Gantry-style load frame with 210 kg mass and reinforced steel construction for enhanced torsional and lateral stiffness.
• High-resolution load measurement system: ±500,000-count resolution at full scale (30 kN), maintaining consistent resolution across the entire force range without auto-ranging or internal gain switching.
• Multi-mode closed-loop control: supports stress-rate, strain-rate, displacement-rate, and load-hold control modes—essential for creep, relaxation, and step-loading protocols required by CMC qualification standards.
• Dual-speed crosshead actuation: independent fast (≥100 mm/min) and fine-adjustment (0.001 mm/min) motion control with jog functionality and programmable return-to-start logic.
• Integrated electronic limit protection and real-time overload detection (>110% FS), plus automatic shutdown for overtravel, overvoltage, overcurrent, and thermal fault conditions.
• Modular fixture interface compatible with standardized ISO 26203-compliant high-temperature grips—including ceramic-coated wedge grips, pneumatic clamping fixtures, and custom-designed CMC-specific jaw geometries.

Sample Compatibility & Compliance

The HY-3080MNRTT accommodates specimens conforming to ASTM C1275 (tensile strength of continuous fiber-reinforced ceramics), ISO 20501 (mechanical testing of advanced technical ceramics), and GB/T 3365–2017 (Chinese national standard for CMC tensile testing). Specimen geometries include dog-bone, straight-bar, and notched configurations up to 380 mm wide and 800 mm gage length. When paired with certified high-temperature environmental chambers (e.g., resistive tube furnaces with MoSi₂ heating elements and inert gas purging), the system meets requirements for GLP-compliant data acquisition per ISO/IEC 17025:2017 Annex A. All hardware and firmware are designed to support audit-ready operation under FDA 21 CFR Part 11 when deployed with validated HENGYITEST software modules.

Software & Data Management

The HENGYITEST professional testing software provides ISO/IEC 17025-aligned data traceability, including user-defined test methods, electronic signatures, and immutable audit trails for all parameter changes, calibration events, and result exports. Real-time plotting supports simultaneous display of up to four synchronized curves: load vs. time, stress vs. strain, displacement vs. time, and strain rate vs. time—with automatic axis scaling, manual zoom, region-of-interest extraction, and overlay comparison of up to 16 parallel tests. Curve analysis tools allow identification and annotation of yield points, fracture initiation, modulus inflection, and post-yield softening behavior. Export formats include CSV, XLSX, PDF reports (with embedded metadata), and XML for LIMS integration. Software validation documentation (IQ/OQ/PQ templates) is available upon request for regulated laboratory environments.

Applications

• Tensile property mapping of SiC/SiC, Al₂O₃/Al₂O₃, and C/SiC composites from room temperature to 1400 °C.
• Interfacial shear strength (IFSS) assessment via microbond or fragmentation testing using specialized mini-grips.
• Creep rupture life prediction under constant load at elevated temperatures per ASTM E139.
• Thermo-mechanical fatigue (TMF) pre-characterization via cyclic loading protocols with thermal dwell steps.
• Quality control of batch-produced ceramic components per MIL-STD-1777 and SAE AMS7075 specifications.
• Research-grade mechanical response modeling for finite element input (e.g., stress–strain hysteresis, damage evolution parameters).

FAQ

Does the HY-3080MNRTT include a high-temperature furnace?
No—the furnace is an optional accessory; the base system is rated for ambient-temperature operation. High-temperature capability requires integration with a third-party or Hengyi-certified furnace system (e.g., vertical split-tube configuration with thermocouple feedback and PID temperature control).
Is the system compliant with ASTM E21 for elevated-temperature tensile testing?
Yes—when equipped with a qualified furnace, calibrated extensometer, and verified specimen alignment procedure, the HY-3080MNRTT satisfies all mechanical subsystem requirements outlined in ASTM E21 Annex A1.
Can the software generate GLP-compliant test reports?
Yes—HENGYITEST software supports electronic signatures, revision-controlled method storage, raw data archiving with hash verification, and timestamped audit logs required for GLP audits.
What extensometer options are supported for high-temperature strain measurement?
The system accepts industry-standard high-temperature clip-on extensometers (e.g., Epsilon 3542 series) and non-contact DIC systems via analog/digital trigger synchronization.
Is remote monitoring and control possible?
Yes—via Ethernet-connected HENGYITEST server mode with TLS-secured web interface; supports real-time dashboard viewing, alarm notifications, and scheduled test execution from off-site locations.
