Effect of different chemical treatments and loadings of Arundo donax L. fibers on the dynamic mechanical, thermal, and morphological properties of bisphenol A aniline based polybenzoxazine composites

Abstract: In this research paper, bisphenol A aniline based benzoxazine (BA-a) was reinforced with natural, inexpensive, and largely distributed cellulosic plant, namely Arundo donax L. (AD) at various loadings of 5, 15, and 25 wt%. AD fibers were initially subjected to three different chemical surface modifications using alkaline, silane, and combined alkali-silane solutions. The main purpose of this work was to investigate the dynamic mechanical properties, morphological stability, and thermal stability of the as-prep… Show more

“…Regarding the mechanical behavior of such composites, these authors also studied the influence of introducing 5, 10, and 15% fibers treated with NaOH, silane, or their combination, as in their previous work (Bessa et al 2020). They found significant increases in glass transition temperature with increased fiber content and reduced damping factor values, especially for silanized fibers (Bessa et al 2021b). Storage modulus increased for all composites, higher for higher loadings, and more significantly for alkali-silane-treated fibers, thus demonstrating a higher compatibility between fiber and matrix.…”

“…Mechanical procedures are the most extended ones in the literature. Most authors process the lignocellulosic material by chopping and grinding it, using the resulting material for obtaining the composites (Fiore et al 2014c, a;Bessa et al 2020Bessa et al , 2021b. Several authors also used this approach for particleboard production (García-Ortuño et al 2011;Ferrández-García et al 2012;Andreu-Rodríguez et al 2013;Ramos et al 2018;Barreca et al 2019;Ferrández-García et al 2019;Ferrández Villena et al 2020b, a;Ferrández-García et al 2020).…”

“…Bessa investigated the thermal characteristics of benzoxazine resin composites reinforced with Arundo donax L. (ADL) fibers. It was shown that the second and third stage of decomposition occurred at 200-300 • C and 350-500 • C, respectively [82]. Fique fibers are typically grown in the South American Andean region and have been used as structural reinforcement material for polymer composites.…”

“…31 Researchers dedicated this decline to the reduced reinforcing effect of filler in composites because of uneven dispersion and agglomeration of filler within the matrix. Analogous and comparable results of DMA were reviewed where benzoxazine and PN resins were customized by the reinforcement of glass fibers, 32 carbon fibers, 5,33 and Arundodonax L. fibers; 34 Pinecone particles, 35 silicon carbide particles, 36 silicon nitride nanoparticles, 37 and zirconia nanoparticles. 38 The reinforcement of these fibers and particles improves E' due to the restriction in chain segment mobility.…”
