摘要:
The design and performance of equipment to measure film toughness under impact loading is described. The measured quantity is the amount of energy absorbed by a film when a ball is projected through it. The velocity of the ball can be varied from about 20 ft/sec to 800 ft/sec. A conditioning chamber permits testing over a temperature range of −40°C to +80°C. Individual tests require a specimen of film of about 1¼×1¼ in. and can be made at the rate of about 2/min. Results are given for films of several commercial materials.
