Overview
The Jiubin JB-117F Honeycomb Core Shear Strength Tester is a high-precision universal mechanical testing system engineered for the quantitative evaluation of in-plane shear properties, peel resistance, and compressive strength of cellular core materials—specifically honeycomb paperboard, aluminum honeycomb panels, and related sandwich composites. It operates on the principle of controlled displacement-driven loading, utilizing a closed-loop servo-controlled actuation system to apply calibrated tensile, compressive, bending, or shear forces per standardized test geometries defined in aerospace and materials science protocols. Designed to meet stringent requirements for structural integrity assessment in lightweight panel manufacturing, this instrument supports both static and quasi-static mechanical characterization under ISO, ASTM, GB, and HB regulatory frameworks—including HB 5443-90 (Aerospace Aluminum Honeycomb Core Rolling Peel Test), GB/T 1453-2005 (Flatwise Compression Test of Sandwich Constructions), GB/T 1455-2005 (Core Shear Strength Test), and GB/T 1457-2005 (Core Shear Modulus Test). Its modular architecture accommodates diverse specimen configurations while maintaining traceable force measurement integrity across its full 20 kN load range.
Key Features
- High-fidelity force measurement with ±0.5% full-scale accuracy, enabled by a calibrated Transcell load cell (USA) and 24-bit A/D conversion via PCI-based digital signal processing.
- Sub-micron displacement resolution (0.001 mm) and ultra-broad speed control (0.001–500 mm/min), supporting both low-strain-rate creep assessments and rapid failure mode analysis.
- Dual-control interface: integrated industrial touchscreen for standalone operation and Windows-based PC software for advanced data acquisition, real-time curve visualization, and multi-parameter synchronization.
- Precision mechanical drivetrain featuring a Panasonic AC servo motor (Japan), ABBA preloaded ball screw (Taiwan), and telescoping dust shield to ensure long-term repeatability and minimal maintenance.
- Auto-ranging force transduction: dynamic switching between measurement ranges during test execution to preserve resolution across low-load adhesion and high-load shear regimes.
- Comprehensive safety architecture including over-travel limit switches, overload cutoff, overcurrent/overvoltage protection, and programmable displacement boundaries.
- Real-time display of force–displacement, stress–strain, and peel-force–distance curves with automatic peak detection, yield point identification, and modulus calculation.
Sample Compatibility & Compliance
The JB-117F is validated for standardized mechanical testing of honeycomb cores per major international specifications: HB 5443-90 (rolling peel of aluminum honeycomb), GB/T 1455-2005 (core shear strength using double-lap shear fixtures), GB/T 1457-2005 (core shear modulus via four-point bending), and GB/T 1453-2005 (flatwise compression of sandwich panels). It also supports non-standardized evaluations of rubber, plastic films, textiles, nanocomposites, and hybrid metal-polymer laminates. Fixture adaptability includes dedicated shear jigs, peel grips (90° and 180°), compression platens, and custom tooling interfaces. All test methods comply with GLP-aligned documentation practices, including audit-ready test logs, operator ID tagging, timestamped raw data export (CSV, XML), and electronic signature support for regulated environments.
Software & Data Management
The proprietary Jiubin TestMaster™ software provides a fully configurable, standards-compliant testing environment. It embeds preloaded test templates aligned with GB, ASTM D3166 (peel adhesion), ASTM C273 (sandwich shear), ISO 11339 (adhesive peel), and DIN 53357 (tensile properties of paperboard). Users may define custom test sequences, set pass/fail criteria, configure multi-stage ramp-hold cycles, and generate compliant reports with embedded metadata (test date, operator, calibration status, environmental conditions). Data files are stored in encrypted local databases with optional network backup; all results support PDF/Excel export and integration with LIMS platforms. The software conforms to FDA 21 CFR Part 11 requirements for electronic records and signatures, including role-based access control, change history logging, and audit trail generation.
Applications
This tester serves critical quality assurance and R&D functions across aerospace component suppliers, packaging engineering labs, composite material developers, and national metrology institutes. Typical use cases include: verification of honeycomb core bonding integrity prior to autoclave curing; comparative evaluation of adhesive formulations for paperboard lamination; certification of fire-retardant-treated honeycomb panels against structural performance thresholds; validation of recycled-content paper honeycomb for sustainable packaging applications; and failure mode mapping of edge-delamination under cyclic shear loading. Its versatility extends to non-honeycomb substrates such as corrugated board, fiber-reinforced polymers, and thin-gauge metallic foils requiring precise shear or peel quantification.
FAQ
Does the JB-117F support automated reporting per GB/T standards?
Yes—preconfigured report templates include mandatory fields from GB/T 1453, 1455, and 1457, with customizable headers, unit formatting, and statistical summaries (mean, SD, CV%).
Can the system perform simultaneous force and displacement control?
Yes—it supports dual closed-loop modes including constant rate of extension (CRE), constant load, and displacement-controlled hold phases with user-defined dwell times.
Is calibration traceable to national metrology institutes?
All force sensors ship with NIST-traceable calibration certificates; on-site recalibration services are available with ISO/IEC 17025-accredited documentation.
What is the maximum specimen thickness accommodated in shear testing?
With standard fixtures, specimens up to 120 mm thick can be tested; custom fixtures extend this to 200 mm upon request.
How is data integrity ensured during long-duration tests?
The system employs non-volatile memory buffering and auto-save at 100 Hz sampling; power loss recovery resumes tests from last valid data point without corruption.
