Hygrothermal effect on natural frequency and damping characteristics of basalt/epoxy composites

Effect of nanoparticles loading on free vibration response of epoxy and filament winding basalt/epoxy and E-glass/epoxy composite tubes: experimental, analytical and numerical investigations

“…Therefore, it is important to avoid the resonant condition by increasing the deviation between the excitation frequency and the natural frequency. Also, the amplitude of the vibration of the composite structure can be controlled by providing the required amount of damping to it, for avoiding the resonance and therefore, to protect the structure from the failure [34]. Although there are several studies [35][36][37][38][39][40] on the mechanical and pressure bursting behavior of FRP tubes and its nanocomposites, the vibration characterization studies of FRP nanocomposite tubes (FRPNCTs) are limited.…”

Determining the strength and thermal­, chemical resistance of the epoxy polymer­composite filled with basalt micronano fiber in the amount of 15–80 % by weight

“…The option to overcome the difficulties may be the manufacture of flat-shaped samples as part of a more complex geometric object. This is the approach used in works [12][13][14][15][16][17][18][19][20][21][22][23][24]. Study [9] shows the possibilities to strengthen the epoxy polymer with nanobasalt fiber, in the amount between 15 and 80 % by weight.…”

Critical Review of the Parameters Affecting the Effectiveness of Moisture Absorption Treatments Used for Natural Composites

“…For example, the twill weave fabrics have optimum mechanical performance even after absorption of moisture. For certain yarn architecture, a lower linear mass density of reinforcing natural yarns provides the composite with greater resistance toward moisture, while retaining at the same time optimum mechanical properties during the moisture exposure period [47][48][49][50][51][52][53][54]. The moisture absorption of natural composites is influenced by the fiber arrangement within the structure of the composite.…”
