“…In Xu et al when adding Gr 5%, it is close to 1.5•10 -5 , but when adding only 2% Ti3SiC2, it reaches 0.5•10 -5 . Similar studies are presented for other types of matrices like thermoplastic UHMWPE [12,13], PI [14][15][16][17][18], PEEK [10,19], thermosetting ((E-44 (6101), SU-8, LY556, CY230) [20][21][22][23][24], metals [25] or oxide coatings [26,27].…”

A series of unidirectional thermoplastic tapes (UD tapes) specimens based on carbon fibers and polyamide filled with fullerene soot in a concentration of up to 4 wt. % was made. A study of the tribological properties by the 3 Ball on Plate test and Ring on Plate test and was made. Shown that the introduction of fullerene soot up to 2 wt. % decreases scatter of CoF in both ranges of load and velocity. Also, this concentration decreases wear rate almost 2.5 times compare to unfilled specimen. Mechanism of friction and wear was suggested. The obtained tribological results are well consistent with mechanical properties, and agree with previously suggested theory of the effect of fullerene soot on adhesion between polymer and fibers.

In this paper, an investigation of tribological properties of 3D printed samples with various filling is performed. The samples are made of biodegradable and non-toxic polylactic acid (PLA) that could be used for medical purposes as well as for rapid prototyping. The sample's properties, such as friction coefficient and temperature in contact area are defined by using the universal friction machine.

В работе приведен анализ результатов лабораторных экспериментальных исследований параметров, характеризующих пластичность, прочность и износостойкость инструментальной стали Р18, полученных в ходе материаловедческих экспертиз. Разработаны новые эмпирические математические экспертные модели зависимости показателей пластичности и прочности стали Р18 от температуры. Получены эмпирические математические экспертные модели зависимости механических свойств и износостойкости стали Р18 от различных факторов. Показана возможность аналитического представления сложных экспериментальных графических зависимостей механических и трибологических свойств стали Р18 от различных факторов в целях использования в судебно-экспертной практике.Ключевые слова: аппроксимация, износостойкость, инструментальная сталь Р18, математическая модель, пластичность, прочность, судебная металловедческая экспертиза, температурная зависимость, трение.Библиография: 52 названий.
