Abstract

Results of experimental study of the elastic modulus of composite polymer materials (glass fiber plastics) by a pulsed ultrasonic method are considered. Results of the in situ elastic-modulus testing in isotropic, transverse-isotropic, and orthotropic glass fiber plastics in articles and constructions are presented. A significant distinction between a dynamic elastic modulus determined by the speed of ultrasound and a static one measured according to GOST (State Standard) 9550-81 is demonstrated. Results of studying the anisotropy of fiber glass plastics are provided.
