Determination of stiffness of dipped skeleton materials - Three - point bending method
1 Scope
This standard specifies the use of two-point bending stiffness principle of three-point bending method to determine the stiffness of dipping skeleton material test method.
This standard is applicable to the determination of the stiffness of dipped rubber materials such as dipped cord cloth, dipped canvas and dipped cord.

4 principle
The test specimen was placed on two support plates (rods) with a defined radius of curvature. The pressure plate (rod) of the test apparatus was placed at 25 mm/min
Speed down, the test sample will be pressed between the two support; record the maximum force required to bend the sample, the force value is the dipping skeleton material hard
The representation of the stiffness, in units of Newton (N).
5 instruments and tools
5.1 Test device
5.1.1 Test device for pull-on dynamometer
The test device used to pull the dynamometer as shown in Figure 1, the relevant parts of the test device should meet the following requirements.
a) the radius of curvature of the face. (3.00 ± 0.05) mm;
b) the radius of curvature of the support face. (2.50 ± 0.05) mm;
c) Distance between support points. (25.0 ± 0.1) mm.
