  • Tensile, Flex, Compression

    • Tensile (ASTM D638, ISO 527, ASTM D1708, ASTM D882): ability to resist breaking in tension (strength)

    • Flex (ASTM D790, ISO 178): ability to resist deformation under load

    • Compression (ASTM D695): ability to withstand compressive loads before fracturing

    • Testing temperatures (-40°C to 250°C)

    Equipment 

      • Tensile/Flex automation system
        • Kuka robotic arm
        • 1 UTM for tensile
        • 1 UTM for flex
        • 1 CMU (cross-section measurement unit)
      • 100 kN floor frame with larger capacity environmental chamber 
      • 50 kN table top frame with environmental chamber
      • 50 kN table top frame
      • 5 kN single column frame (small parts, films, filaments)

    Specimen/Sample Types

    • ISO - Type I

    • ASTM - Type I, IV, V, 1BA, microtensile, film




    Impact 

    • Izod (ASTM D256, ISO 180) pendulum impact

    • Charpy (ISO 179) pendulum impact

    Testing temperatures (-40°C to 23°C)

    • Equipment
      • Izod/charpy automation system
        • Kuka robotic arm
        • Three impact testers
        • 1 CMU (cross-section measurement unit)
        • 1 TMU (depth under the notch measurement unit)
        • Notch and break detection
        • Hammers
          • Izod: 2.75J, 5J, 7J, 11J
          • Charpy: 
      • Izod/charpy pendulum impact tester (manual)


    • Multi-axial impact (-40⁰C to 100⁰C, ASTM D3763)
      • Drop/Instrumented impact with load-deflection curves

    • HDT/Vicat (ASTM D648, ISO 75, ASTM 1525, ISO 306)
      • Temperature at which plastic deformation takes place under load
      • Investment in new machine with more automated sample loading and safety features

    • Hardness
      • Rockwell Hardness Scales M, R, E (ASTM D785, ISO 2039) & Shore A,D (ASTM D2240, ISO 7619)
      • Measurement of resistance to localized plastic deformation
      • Replacement of both hardness testers allows for PC connection for data transfer

    • Density/Specific Gravity (ASTM D792, ISO 1183)
      • Invested in new balance to allow for automatic measurement transfer to PC

    • Flammability testing (UL94)
      • Vertical and horizontal burn
      • New flame chamber coming in Q4 2022. New chamber features a semi-automatic design with spindle system for positioning samples and burner and built-in gauges for flame height and samples.  

    • Other available tests: water absorption, tensile fatigue, shear stress, lap shear, mold shrinkage, shear punch, adhesive/peel, taber abrasion, filament tensile, fiber tensile, pin-adhesion




    Composite & Thermoplastic Composites (TPC)

    Testing in Composites & TPC materials 

    • Tensile D3039, Flex D7264 (-40⁰C to 200⁰C)
    • Short beam shear D2344 (-40⁰C to 200⁰C)
    • Compression D6441 & D695 (-40⁰C to 200⁰C)
    • In-plane shear D3518 (-40⁰C to 200⁰C)
    • GIC, GIIC
    • In house “T-pull” test for overmolded specimens

    New Investments

    • 100 kN load frame with environmental chamber 
    • VideoXtens 
      • Non-contact strain measurements for a variety of tests
      • Eliminates need for strain gauges
    • GIC camera assembly - allows for crack propagation tracking in real time
