Mechanical and thermal properties of polypropylene/modified basalt fabric composites

Abstract

Basalt fabric (BF) was first treated with silane coupling agent KH550, modified basalt fabric (MBF) was obtained. Then MBF were molded with polypropylene (PP) matrix, and polypropylene/modified basalt fabrics (PP/MBF) composites were obtained. The influence of concentration and treating time of KH550 on MBF were characterized by hydrophilicity and lipophilicity. The tensile strength and morphology of basalt fabric were tested by single filament strength tester and scanning electron microscopy. The mechanical properties of composites were measured with electronic universal testing machine and impact testing machine, and the thermal properties were tested by thermogravimetric analysis and dynamic mechanical analysis. The results showed that the lipophilicity of MBF is improved significantly by KH550 while the tensile is nearly damaged. The mechanical properties of composites are larger than that of pure PP, among which the impact property was improved the most, showing 194.12% enhancement. The thermal stability and dynamic viscoelasticity were better than pure PP; furthermore, the concentration of KH550 virtually had no effect on the thermal stability.

High‐performance polymeric materials with greatly improved mechanical and thermal properties from cyanate ester/benzoxazine resin reinforced by silane‐treated basalt fibers

“…The increase in the T g values of the composites could be evidently connected by the progressive incorporation of the TBFs within the resin matrix. Guo et al . reported that the high fiber/matrix adhesion could strongly lower the polymer chain mobility and consequently increase the T g of the produced composites.…”

“…reported that the high fiber/matrix adhesion could strongly lower the polymer chain mobility and consequently increase the T g of the produced composites. Hence, the increase in the T g could be justified by the better interfacial adhesion of the TBFs within the CE/BOZ resin achieved by using the SCA, which might restrict the polymer chain mobility . To clarify more, the addition of TBFs to the CE/BOZ resin acted as a hindrance and later increased the heterogeneity of the crosslinked network of the reinforced polymer composites.…”

Silane-Treated Basalt Fiber–Reinforced Poly(butylene succinate) Biocomposites: Interfacial Crystallization and Tensile Properties

“…KH550 (NH 2 CH 2 CH 2 CH 2 Si(OC 2 H 5 ) 3 ), an economical organo-silane, was adopted in this study. Silane treatment has proved to be a low-cost and efficient method to endow the fiber-matrix an improved interfacial bonding [26][27][28].…”

“…Basalt fiber-reinforced plastics (BFRPs) are newly emerging composite materials due to their being recyclable, cost effective, and lightweight [1][2][3][4]. Basalt fiber (BF), produced by abundant natural basalt rocks, is a promising fiber reinforcement, which endows basalt fiber with excellent chemical, weather, and heat resistance [5,6].…”

Basalt Fiber Modified Ethylene Vinyl Acetate/Magnesium Hydroxide Composites with Balanced Flame Retardancy and Improved Mechanical Properties

“…For examples, Attia et al [ 18 ] synthesized an organic polyaniline directly on the surface of BF and formed an organic polymer shell on the surface of the inorganic fiber—the tensile strength property was enhanced by 38% and 53% compared to blank and unmodified basalts, respectively. Guo et al [ 19 ] treated BF by using the economical silane agent γ-aminopropyl triethoxysilane (KH550) as a modifier, which showed 194.12% enhancement in impact strength compared to that of pure polypropylene (PP). Zhang et al [ 20 ] modified BF by grafting organic/inorganic composites, and attaching a biofilm rich in microorganisms for wastewater treatment.…”
