NEW PREPREG Russian patent published in 2003 - IPC

FIELD: chemical engineering. SUBSTANCE: polymer matrix is selected as multiphase matrix having the first matrix ingredient composed of monomer or dendrimer and the second ingredient containing organic molecules of high molecular mass, the latter forming sticky shell enveloping the prepreg having interpenetrating polymer network bond with the first matrix ingredient. The prepreg preferentially has the third ingredient containing organic molecules of high molecular mass. The third ingredient occupies space between fibers. EFFECT: high quality of fiber material reinforcement; improved mechanical properties. 20 cl, 4 dwg
