Method for measuring tensile strength of rings made from composite materials under the impact of external pressure and the test stand for measuring tensile strength of rings made from composite materials under the impact of external pressure

摘要

how to measure the tensile strength of the rings made of composite materials to the internal pressure is such that the test sample (4) in the form of rings made of composite materials is subjected to the action of uniformly rozu0142ou017c the defendant's internal pressureplacing it between the inner ring and the outer ring (1) osu0142onowym osu0142onowym (2), which are attached permanently to the lower plates (3).the space between the sample test (4) and the outer ring (2) osu0142onowym filled insulation (5) of flexible material, and between the sample test (4), and the internal ring osu0142onowym (1) placed torus (8) of a flexible material, then covers s will all top plate, connected rigidly with the lower plate (3), after which the filled torus (8) airuntil the destruction of the test sample (4), the read value of the manometer pressure destroying digital (11), a tensile strength, and compared with the tensile strength pomierzonu0105 on samples subjected to creep phenomenon.the test shall be carried out on three samples minimum research (4) of the same composite material, and the results of the maximum pressure are averaged.position to measure the endurance rings made of composite materials for internal pressure is characterised by having the inner ring cover (1) and outer ring (2), which cover is attached permanently to the lower plates (3).at the inner ring osu0142onowym (1) is placed first cienkowarstwowy insulating collar (7), the torus (8) and second cienkowarstwowy insulating collar (7), and by the outer ring (2) is osu0142onowym insulation (5) of flexible material, and between the second c ienkowarstwowym insulating flange (7) and insulation (5) is a space for placing the test sample (4),the position has a top connected rigidly with the lower plate (3), and the torus (8) is connected by a digital pressure gauge (11) of the supercharger (l2).
