Tribo‐mechanical properties of composites based on polyoxymethylene reinforced with basalt fiber andsilicon carbidewhiskers

Abstract

This paper presents an analysis of the hybrid reinforcement of polyoxymethylene composites. Basalt fibers and monocrystalline silicon carbide fibers were used as reinforcement. Basic tests of mechanical properties were carried out, such as the static tensile and flexural test. The tests were repeated under external factors, such as the influence of water aging and a wide range of exploitation temperatures. The materials were also subjected to tribological tests, that is, determination of the friction coefficient and the specific wear rate. Strength tests revealed an increase in the stiffness of the material as well as a reduction the friction coefficient and abrasive wear. The addition of monocrystalline fibers significantly limited water absorption, stabilized the strength properties in the water environment as well as provided better material's resistance to dynamic impact.

Effect of combined micro and nano silicon carbide particles addition on mechanical, wear and moisture absorption features of basalt bidirectional mat/vinyl ester composites

“…[ 19 ] While laying the basalt mat care should be taken to completely wet the interface of basalt mat with the matrix resin. Vinyl ester resin with 6% MEKP as catalyst, 6% cobalt napthanate as accelerator, and 12% acetyl acetone as promoter were mixed using mechanical stirrer for matrix preparation [ 29 ] The nano and micro particles of SiC were added as filler material along with resin from 2 to 10 wt% in steps of 2 wt% equally shared between nano and micro SiC particles. The trapped air bubbles were carefully removed using a roller and allowed to cure under a load of 200 N for 24 h. The prepared composition of the composites listed in Table 3 were investigation of its mechanical, wear and water absorption properties done.…”

Investigation of the effect of zeolite, bentonite, and basalt fiber as natural reinforcing materials on the material properties of PPS and CF‐reinforced PPS

“…[12] Although it is one of the most preferred composite production methods to reinforce polymers with high strength and modulus fibers such as glass, carbon, and Kevlar for use in engineering applications, researchers are looking for the use of environmentally friendly natural additives to replace synthetic fibers. [13][14][15][16] In fiberreinforced composites, on the other hand, low fiber-matrix interfacial interaction or undesired orientation of the fibers is an important problem. [17,18] In the case of particle and fiber reinforcement together, achieving a hybrid structure the fibers provide better dispersion of the particles and the particles increase the interaction of the fiber-matrix interface, creating a synergetic effect, resulting in superior material properties.…”

Effect of blending cashew oil modified phenolic resin and nitrile rubber on thermal, mechanical, and tribological performance of friction materials

“…At present, the brake friction materials have formed the system and are mainly dominated by powder metallurgy friction materials, composite carbon friction materials, and organic synthetic friction materials, [9] with the organic synthetic friction materials having greater development potential owing to their strong designability, simplicity of process, light weight, and ease of mass production. [10] Actually, organic synthetic friction materials are multicomponent systems and primarily categorized into four groups based on their involvement: binders, reinforcement fibers, friction modifiers, and fillers. [11,12] The binder in the friction material is cured by heat and binds the components together in the form of bonded film, generating a so-called sea-island structure at the submicroscopic level, and presenting a dense whole in appearance.…”
