Split-disk test method

Different mandrel rotational speeds, consolidation pressures, and preheating and consolidation temperatures were used to manufacture pipes from towpregs and to verify the influence of these processing parameters on the mechanical properties. The circumferential tensile strength of the pipes was tested in an Instron 4505 machine using the split disk test method according to ASTM 2290 at a crosshead speed of 1 mm/min. 

The fiber mass fraction, and the flexural and tensile properties of the continuous fiber-reinforced composites produced by various techniques were determined according to ISO 1172, ISO 178, and EN 60, respectively. The split disk test method according to ASTM 2290 was employed to determine the circumferential strength and modulus of the pipes produced by filament winding. 

A wide variety of analogous experiments with different conditions of pressure, velocities, surface characteristics, and temperature are required to fully characterize the friction phenomenon at variable sliding speeds. Various research techniques are available for the study of dynamic friction such as pressure-shear plate impact frictional experiments, Split-Hopkinson bar method, pin-on-disk tests, and others, ranging from quasistatic conditions to very low sliding velocities. At low velocities (Vc < 1 m/s), for steel-on-steel non-lubricated contact of sliding surfaces, the friction coefficient demonstrates a strong...
