toughness

toughness and tenacity test

The impregnated resin should be of high toughness and well permeant to glass fiber.

The toughness may be well improved by postheat treatment which is large in energy consumption and long in working period.

It is proved that the pressmark of tooth root, the state of carbide and remanentelements in the material have different effects on the toughness of POwer hacksaw blades.

It is shown that the fracture properties are determined by materials strength before tufftride process and by materials toughness after tufftride process.

A high K ratio method for fatigue precracking in welding position toughness specimen of thick steel plate was developed.

Good toughness and thermal cracking resistance.Used in the stands of prefinish rolling.Suitable for hot rolling thread steel.

Results showed that the flexual strength and the flexual toughness index of UHPC become more than 2 times and 10 times respectively of those 0f the matrix concrete by the reinforcement of fibers.

As oriented arrangement can highly enhance toughness of non-metallic inorganic materials, resulting in aeolotropism of mechanics and other physical properties, there are increasing recognition on it.

Glass fiber is used to reinforce material for increasing toughness, flexural strength, and tensibility in unsaturated polymer modified concrete.
