Abstract
Investigations of mechanical properties of textolite and glass fiber in the test for flat straight bending were carried out. To study the deformation dependence e voltage s was designed and manufactured corresponding to the experimental setup. It was found that the strength properties of glass better in 1,5 at destruction than the PCB, and the deformation characteristics are almost the same. The measured experimental curves are satisfactorily described by the exponential model proposed by the authors. It is shown that the experimental dependences of s on lgt are nonlinear, which indicates the dependence of the mechanical stress of the textolite and glass-textolite material on the load speed.
