For discontinuous cellular bonded surfaces, specimen geometry is base on cell size. Due to the very large number of tests adtm, descriptions of those most commonly requested have been gathered into the following groups: The standard Wyoming fixture shown utilizes bonding blocks 1″ square in cross section, the minimum size recommended in ASTM Standard C The adhesive must then be allowed the appropriate conditioning before testing.
Tensile Strength of Sandwich Constructions ASTM C
Permissible cc297 materials include those with a continuous bonding surface balsa wood and foams as well as those with a discontinuous bonding surface honeycomb. To request a quote for this test or others Click Here. One type of bonding fixture is shown in Fig. Core-to-facing bond integrity is necessary to maintain facing stability and permit load transfer between the facings and the core. Other designs, for use with both square and circular specimens, are asgm available.

Software for Series Systems. Assurance Testing Inspection Certification.
Results may also provide information on flatwise tensile strength data of the core material. Elevated or Reduced Adtm Test Procedure: The test ASTM C provides information on core-to-face bonding stability, load transfer and flatwise tensile strength of sandwich core material.
Description Literature Contact Us Flatwise tensile strength of sandwich construction is a measure of the strength between the substrate and the core material.
Bluehill LE for Basic Testing. Standard test fixtures asgm installed inside the chamber, and testing is conducted inside the controlled thermal environment the same as it would be at ambient temperature.

Email addresses can only contain letters, numbers and the following special characters: Since the physical properties of many materials can vary depending on temperature, it is sometimes appropriate to test materials at temperatures that simulate the intended end use environment. A thermal chamber is installed on the universal test machine. The chamber is designed to allow the test mounts from the base and crosshead of the test machine to pass through the top and bottom of the chamber.
