| Abstract: | The change in the adhesive strength of resin-fiber compounds modified by polyarylene ether ketone in the process of curing
is studied. It is shown that the dependence of adhesive strength on the time of curing is described by a curve with a maximum.
The form of the curve results from the residual stresses that arise and develop at the interface. It is also shown that using
the epoxy polymer blends makes it possible to markedly increase the strength of the matrix-fiber interface. |
