Novel glass fabric-reinforced polybenzoxazine–silicate composites with polyvinyl butyral for high service temperature applications

Abstract

The aim of this study is to develop novel glass fabric-reinforced polybenzoxazine–silicate composites with enhanced performances, which can overcome the disadvantages related to the low crosslink density of glass fabric-reinforced polybenzoxazine composites.

Recent developments in the polybenzoxazine based bionanocomposites: A review

“…The creation of nanocomposites using variety of nanofiller sizes and shapes that includes spherical, polyhedral, nanowire, nanofiber, nanotube, porous structures, and one-dimensional disc-like nanoparticles has been reported for specific applications such as laminates, composites, bindings, adhesives, and protective coatings. 28,29 1.3 | Organic-inorganic hybrid nanocomposites One essential component of functional nanocomposites is hybrid nanomaterials that are made of both organic and inorganic components. More surface reactions are often encouraged by the high surface-to-volume ratio of hybrid nanomaterials.…”

“…More benefits than traditional reinforcements are provided by nano‐reinforcement materials, which also have a larger surface‐to‐surface ratio, improved adhesion between the nano‐reinforcement and polymer chains, and a lower loading to achieve comparable qualities. The creation of nanocomposites using variety of nanofiller sizes and shapes that includes spherical, polyhedral, nanowire, nanofiber, nanotube, porous structures, and one‐dimensional disc‐like nanoparticles has been reported for specific applications such as laminates, composites, bindings, adhesives, and protective coatings 28,29 …”

Thermally stable, flame retardant, low‐dielectric constants, and flexible thermosetting resins based on a tetra‐functional benzoxazine compound possessing a cyclic siloxane core

“…1,3 On the other hand, functionalization of benzoxazine compounds and the corresponding resins with siliconcontaining groups has received much research attention. [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25] The first example could be dimethylsiloxanecontaining benzoxazine compounds. [11][12][13][14][15][16][17] In addition to enhancing the toughness of the benzoxazine resins, the silicon-containing groups have also significantly increased the thermal stability, char yield (CR) at high temperatures, and flame retardancy of the silicon-containing benzoxazine resins.…”

“…Liu et al 20 utilized BA-TAS as a monomer in preparation of benzoxazine resin-silica nanocomposites through sol-gel reaction. Moreover, silicon-containing benzoxazine compounds, including polydimethylsiloxane benzoxazine, 21,22 ethyl silicate, 23 POSS-benzoxazine, 24,25 have also been utilized for modification of conventional thermosetting resins enhancing the thermal stability, yield, and flame retardancy of the resins.…”

Excellent antioxidizing, thermally insulating and flame resistance silica‐polybenzoxazine aerogels for aircraft ablative materials

“…To a certain extent, PBO can effectively improve the relatively low char rate and mechanical strength by designing molecular structure; however, the heat resistance and oxidation resistance still need to be further improved. To our best knowledge, silicon modification for PBO can increase the thermal stability, mechanical strength, and mass residual rate, [14][15][16][17] and enhance the ablation resistance and flame retardancy. [18][19][20] Devaraju et al 18 designed and prepared an environment-friendly PBO and SiO 2 hybrid material (PBO-C-F-S), its mass residual rate increased 37.52% compared with pure PBO, and the limiting oxygen index (LOI) increased from 21.94 to 36.95.…”
