Physical-mechanical properties of andesite-dacite fibers and their modifications
AI summary Read the abstract
Andesite-dacite volcanic rock fibers were characterized for elastic and mechanical properties, showing strength characteristics comparable to non-alkaline glass and basaltic fibers when fabricated into unidirectional composite microplastics. This materials characterization study of mineral fiber composites is unrelated to environmental microplastic pollution or health impacts.
The properties of mineral fibers consisting of andesite-dacite, which is an effusive volcanic rock, are studied. The elastic-strength characteristics of elementary fibers, filaments, and also microplastics and plates consisting of unidirectional composites fabricated from filaments and ÉDT-10 epoxy binder are investigated. It is shown that the characteristics of the fibers are quite high and close to the properties of non-alkaline glass and basaltic fibers.

Realization of the strength of Armos fibres with different acidity in epoxy plastics
AI summary Read the abstract
The acidity of Armos aramid fibers significantly affects their strength realization in microplastic composites, with an optimal moisture content existing for each fiber pH level that maximizes both fiber strength and adhesive bond performance. Optimizing fiber-matrix interfaces in polymer composites to maximize strength retention is directly relevant to reducing mechanical degradation and microplastic generation from composite plastic materials.

AI summary Read the abstract
Impregnating Lavsan (polyester) fibers with oligourethane acrylate binder was shown to increase the strength, thermal stability, and dimensional stability of composite microplastic specimens, with higher binder content reducing crystallite disorientation. This polymer composite fabrication study is unrelated to environmental microplastic pollution or associated health risks.
Creep and recovery of cellulose acetate microfiber bundles
AI summary Read the abstract
Researchers characterized the mechanical behavior of cellulose acetate microfibers from cigarette filters using dynamic mechanical analysis and finite-element modeling, finding that smoking, temperature, and applied stress all affect creep and recovery properties, establishing a baseline for understanding how these fibers degrade after being littered into the environment.
