Formation of a strong joint between the fiber and the matrix in composite material polyethylene plastic

“…Decreasing the filament diameter leads to growth of an interphase boundary between the fiber and the matrix, which becomes one of the most important structural components of the material; changing the interaction of the components on the interphase boundary allows adjustment of the properties of CMs in a wide range [1,2].…”

“…Chemical interaction begins on active centers of the reinforcing fiber, so activation of the fiber by special processing makes it possible to stimulate its ability to interact with the matrix material and as a result to change the prop erties of the CM [2].…”

Properties of ultra high molecular weight polyethylene fibers after ion beam treatment

“…Recently modification of polymer materials by ion beam surface treatment (IBST) has drawn increasing attention of the researchers. IBST induces structural changes in the surface layer of the polymer film, the depth of the modified layer, and its chemical composition being dependent on the treatment conditions and type of the ion 3, 4. For example, in Ref 3.…”

“…A number of attempts to create a composite based on modified UHMWPE fibers have been already made, for example, filament‐wound composite consisting of “cold” plasma‐treated PE fibers and epoxy matrix4 and high strength fabric from UHMWPE Spectra 1000 fibers treated by gas‐plasma prior to the composite lay up, the latter being tested for radiation shielding properties 21. However, there is no technology which can be considered an optimal one from the point of view of adhesion improvement without the change of the ordered fiber structure.…”
