is a continuous phase and the elastomeric polymer is a discontinuous phase another attribute of the elastomeric polymer is that it is selected with reactivity and appropriate end groups so that as the elastomeric polymer cures it may also to some extent crosslink with the structural polymer in another embodiment the part one polymer may be initially a two phase system wherein the structural polymer is a liquid phase and the elastomeric polymer is a cured or partially cured elastomeric polymer in solid form such as a fine powder dispersed in the liquid structural polymer when the structural polymer cures it forms the continuous phase encasing and entrapping the elastomeric polymer particles as the discontinuous phase this embodiment may be useful in some structure reinforcement applications but care must be taken to keep the elastomeric polymer particles dispersed in the liquid structural polymer during application and curing in a preferred method of application the present invention further includes applying the fiber reinforced polymer system by coating a plurality of fibers with the polymer system coating the external surface of the structural member with the coated fibers and then applying a force to the coated fibers thereby embedding the fibers within the polymer system it will be apparent to one skilled in the art following the disclosure herein that each of the structural polymer and the elastomeric polymer components of this invention can be selected according to the properties and conditions desired each polymer can be selected with respect to chain length molecular weight.
