These test methods cover the tensile testing of aramid threads, twisted cables from these yarns and fabrics from these cables. The yarn or cord can be wound on cones, tubes, coils, chokes, or beams; It can be woven into fabric; or they can be realized in some other form. The methods include test procedures and include no specifications or tolerances.…
Tensile tests measure the force required to break a plastic sample specimen and the extent to which the specimen stretches or elongates to that breaking point. ASTM D-638 tensile test procedure: Specimens are placed in the grips of the universal tester at a specified grip separation and pulled until failure. For ASTM D 638 the test speed is determined by…
Upper and lower bonding blocks of the equipment are realized each with a double yoke arrangement. This conformation is made in order to allow full alignment of the sample during tensile load. On the testing machine there is an attachment standard 1.25″ diameter male studs with 0.50″ diameter cross-pin holes. The bonding blocks have 1″ square ends. The life of…
This fixture is useful to indicate the curved beam strength of a continuous fiber – reinforced composite material. For the test run it is necessary to use a curved beam sample 90 ° that has to be positioned for the four-point-bending test apparatus in order to be loaded. The curved beam is composed of two straight legs joined by a…
