Hengyi HY-0580TYBB Carbon Fiber Composite Compression & Flexural Strength Testing Machine

Overview

The Hengyi HY-0580TYBB is a precision-engineered electromechanical universal testing machine designed specifically for static mechanical characterization of advanced lightweight composites—particularly carbon fiber-reinforced polymer (CFRP) laminates and hybrid structures. It operates on the principle of controlled displacement actuation via a high-fidelity servo-motor-driven lead screw system, enabling accurate application of axial compressive, flexural, tensile, and shear loads under closed-loop feedback control. The machine conforms to fundamental metrological requirements defined in ISO 7500-1 (static calibration of force-measuring systems), ASTM E4 (load verification), and ISO 5893 (tensile testing machines). Its modular architecture supports interchangeable load cells (1 N to 5 kN full scale), adjustable crosshead travel (800 mm), and programmable test profiles—making it suitable for both standardized compliance testing and R&D-grade material property mapping.

Key Features

• Single-column, space-efficient structural design with rigid aluminum alloy frame and precision-ground guide rails for minimal lateral deflection during high-stiffness CFRP bending tests.
• High-resolution force measurement system with ±0.5% accuracy across the entire 5 N–5000 N range, utilizing temperature-compensated strain-gauge load cells and 500,000-count A/D conversion without internal range switching.
• Sub-micron displacement resolution (0.001 mm) achieved via optical encoder feedback integrated into the servo drive system—critical for accurate modulus determination in low-strain regimes typical of CFRP flexural testing.
• Wide dynamic speed range (0.001–500 mm/min), digitally regulated with ±0.5% speed fidelity—enabling slow-rate creep or relaxation studies as well as high-speed fracture propagation analysis.
• Dual-mode motion control: manual jog operation for rapid specimen alignment and automated programmable sequences for multi-step protocols (e.g., preload → ramp → hold → unload).
• Integrated safety architecture including electronic stroke limits, overload cutoff (110% FS), real-time diagnostic monitoring of motor current, voltage, and thermal status, and emergency stop with hardware interlock.
• Modular fixture interface compliant with ISO 26203-2 and ASTM D7264/D3410 mounting standards—supporting three-point bending fixtures, compression platens, wedge grips, and custom tooling for non-standard geometries.

Sample Compatibility & Compliance

The HY-0580TYBB accommodates specimens conforming to standard dimensions specified in ISO 14125 (flexural properties of FRP composites), ASTM D7264 (flexural strength/modulus of polymer matrix composites), ASTM D3410 (compressive properties of CFRP), and GB/T 3354 (Chinese national standard for carbon fiber composite mechanical testing). It supports flat laminate strips (up to 120 mm wide × 800 mm long), cylindrical rods, and molded structural coupons. All force, displacement, and strain data acquisition meets traceability requirements per ISO/IEC 17025 for accredited laboratories. The system satisfies essential regulatory expectations for GLP-compliant environments—including audit-ready event logging, user-access controls, and timestamped raw data export—though native 21 CFR Part 11 compliance requires optional software validation package.

Software & Data Management

The instrument is operated via Hengyi’s proprietary PC-based control suite, supporting Windows 10/11 and offering dual-language UI (English/Chinese). The software implements real-time PID-controlled load/displacement/stress/strain regulation, with customizable test templates aligned to ASTM, ISO, GB, and JIS methodologies. Raw data is saved in ASCII CSV format with metadata headers (test ID, operator, date/time, calibration ID, environmental notes). Export options include graphical overlays (stress–strain, load–deflection), statistical summaries (mean, SD, CV%), and batch reporting for multi-specimen qualification. Data integrity safeguards include automatic checksum generation, write-once storage mode, and tamper-evident file naming conventions. Optional API integration enables connection to LIMS or MES platforms via TCP/IP or OPC UA.

Applications

• Determination of flexural modulus and strength (ASTM D7264) for aerospace-grade prepreg laminates and out-of-autoclave cured panels.
• Short-beam shear testing (ASTM D2344) to evaluate interlaminar shear strength in thermoset and thermoplastic CFRP systems.
• Compression-after-impact (CAI) preloading and residual strength assessment per ASTM D7137.
• Quasi-static tensile characterization of unidirectional and woven carbon fabrics (ISO 527-4/5, ASTM D3039).
• Creep and stress-relaxation behavior quantification under constant load or displacement conditions.
• Validation of finite element models through experimental correlation of load–deflection curves and failure initiation thresholds.
• Quality assurance testing in production environments for automotive CFRP components (battery enclosures, chassis substructures).

FAQ

What standards does the HY-0580TYBB support out-of-the-box?
It includes preconfigured test methods for ASTM D7264, D3410, D3039, ISO 14125, ISO 527-4, GB/T 3354, and GB/T 16491—with editable parameters for custom protocol development.
Can the system be upgraded for higher load capacity?
No—the HY-0580TYBB is fixed at 5 kN maximum capacity; for loads beyond 5 kN, Hengyi offers the HY-1080 series (10 kN) or HY-2080 series (20 kN) with identical software and compliance architecture.
Is third-party calibration certification included?
Factory calibration is performed per ISO 7500-1 and documented in the delivery dossier; ISO/IEC 17025-accredited calibration certificates are available as an add-on service.
Does the machine support video extensometry integration?
Yes—via optional USB3.0 digital camera module and DIC-compatible software extension, enabling non-contact strain field mapping during bending or compression tests.
What maintenance intervals are recommended?
Lubrication of lead screw and guideways every 6 months; annual verification of load cell linearity and encoder resolution; biannual firmware/software updates provided free of charge for registered users.
