Mechanical Testing
Tension
HPI specializes in coupon testing of fiber reinforced polymer composite materials per ASTM D638 and D3039. Our 60,000 pound capacity universal test frame can deliver calibrated loads to a wide range of laminates. Contact us today for a custom quote for your tensile testing needs. D3039 and ISO527-2 and -5 are accredited tests.
Compression
HPI accommodates an array of compression test methods including ASTM D6641, ASTM D695, open hole ASTM D6484, and bolt bearing. Test preparation includes precise machining and can also include strain gage instrumentation. D6641, D695, ISO 14126 are accredited tests.
Flex
HPI can tests a wide variety of specimen sizes in 3- or 4-point flexure. Specimens can be prepared from flat panels to non-typical structures for flexure evaluation. D7264 and ISO 178 are accredited tests.
Shear
Shear testing of fiber-reinforced polymer composite materials is vital to providing quality data inputs for material modeling. HPI can test to all ASTM shear standards for both in-plane and interlaminar shear behaviors. ASTM's D5379, D2344 and ISO 14129 and 14130 are accredited tests.
Pull-Off Strengths for Coatings and FRP
With our portable tester HPI can determine the pull-off strength of coatings, adhesives (ASTM D4541), or laminate systems. ASTM D7522 Pull-off strength for FRP bonded to concrete is an accredited test.
Climbing Drum Peel
ASTM D1781 is a great test when evaluating sandwich structures. This test produces strength data for the adhesive between core and facing materials.
PrePreg Testing
HPI is accredited for several prepreg evaluations including Gel time, resin flow, Volatile content, and Constituent content.
Impact
HPI can provide impact testing of neat resin samples following Charpy and V-notched methods.
Hardness
When evaluating a new resin system, hardness testing is a great indicator of cure completion. By using our Shore A or Shore D durometers HPI can help.
Environmental Conditioning
Will your material be used in non-ambient conditions? HPI can pre-condition specimens to your exact end use requirements, such as high humidity and elevated temperature or sub-ambient temperatures.
Timber Testing
HPI will evaluate wood products from CLT, Glu-Lam beams to custom timber products.
Heated Platen Press for Flat Panel Fabrication
Our new Heated platen press enables us to make flat panels with your specific material system.
Physical Testing
Neat Resin and Composite Characterization
Fiber Volume by Acid Digestion
Determination of carbon composites fiber volume or content by Nitric Acid digestion. ASTM D3171 Constituents of Composite material is an accredited test
Fiber Volume by Burn-off
Determination of glass composite fiber volume or content by burn-off method.
Microscopy
HPI can provide microscopic images of failure surfaces as well as inspect samples for resin and fiber bonding.
