A Property of Synthetic Resins: Materials which are Extremely Resistant to Disintegration from Shocks and Vibration Available to Purchase

SYNTHETIC resins reinforced with fahric have proved in actual service to be not only resistant to disintegration from shocks and vibration but also to have remarkable freedom from “notch sensitivity.” In order to investigate this property measurements were made of the energy absorbed by such materials under torsional oscillation; it was found that the energy absorbed was greater than that of any other comparable materials (such as wood or metal).
