Influence of Activation of Reinforcing UHMWPE Fibers on the Properties of Composite Materials
The article presents the results obtained in the study of the influence of UHMWPE fibers activation by nonequilibrium low-temperature plasma of a radio-frequency capacitive discharge at reduced pressure and direct fluorination on the properties and failure mode of the fibers and composite materials based on them. The application of activated UHMWPE fiber for reinforcing epoxy and epoxy-urethane matrices makes it possible to produce light-weight composite materials (CM) with high physicomechanical indices. The interaction between the fiber and the matrix during the production of CM can be increased both by activating the fiber and by choosing the composition of the matrix. The plasma treatment and direct fluorination appeared to be particularly effective for study of the effect of fiber activation on the bending and shear properties of the composite, thus demonstrating a high increase in the interaction at the fiber/matrix interface. After the plasma treatment of SK-75 fibers, the composites based on Epicot-828 and EPUR matrices had increased bending strength σb by a factors of 3 from 155 to 470 MPa and 2.96 (about 3) from 145 to 430 MPa, respectively. The shear strength τsh increased by the factors of 1.66 from 12 to 20 MPa and 1.57 from 18 to 30 MPa for the composites reinforced with plasma-activated SK-75 fibers based on Epicot-828 and on EPUR matrices respectively. The composite shear τsh and bending strength σb increased by the factors of 2.2 from 10 to 22 MPa and 2 from 160 to 320 MPa for CM based on Epicot-828 reinforced with activated SK-75 fibers by direct fluorination. Activation of the fiber with the help of plasma and fluorination allows оne to make polyethylene plastic a monolithic composite. The failure mode of such composites points to the high strength of the bond between the fiber and the matrix.
期刊介绍：
Inorganic Materials: Applied Research contains translations of research articles devoted to applied aspects of inorganic materials. Best articles are selected from four Russian periodicals: Materialovedenie, Perspektivnye Materialy, Fizika i Khimiya Obrabotki Materialov, and Voprosy Materialovedeniya and translated into English. The journal reports recent achievements in materials science: physical and chemical bases of materials science; effects of synergism in composite materials; computer simulations; creation of new materials (including carbon-based materials and ceramics, semiconductors, superconductors, composite materials, polymers, materials for nuclear engineering, materials for aircraft and space engineering, materials for quantum electronics, materials for electronics and optoelectronics, materials for nuclear and thermonuclear power engineering, radiation-hardened materials, materials for use in medicine, etc.); analytical techniques; structure–property relationships; nanostructures and nanotechnologies; advanced technologies; use of hydrogen in structural materials; and economic and environmental issues. The journal also considers engineering issues of materials processing with plasma, high-gradient crystallization, laser technology, and ultrasonic technology. Currently the journal does not accept direct submissions, but submissions to one of the source journals is possible.
