“…This macroscopic shear fracture can be considered to have progressed from kinking initiation. Since these mechanisms of compression failure initiation depend on matrix strength (Pilato & Michno, 1994), the compressive strength is directly related to the temperature-dependent matrix strength.

“…The following published data obtained at only RT were found. OHT/NHT strength ratios are 57% for T650-35/Radel 8320 CF/thermoplastic resin (Pilato & Michno, 1994), 58% for T800S/3900-2B and 56% for T800H/3900-2 CF/epoxy (JAXA, 2007). OHC/NHC strength ratios are 52% for T800H/F655-2 CF/BMI (Marais et al, 2001) and 51%-53% for T800S/3900-2B and T800H/3900-2 CF/epoxy (Nagao et al, 2007).…”

Neste trabalho, a lignina extraída pelo processo organossolve do bagaço de cana-de-açúcar substituiu parcialmente fenol (40% em massa) em matrizes termofixas reforçadas com fibras curtas de bagaço de cana-de-açúcar (30, 40, 50, 60 e 70%, v/v). Os compósitos obtidos foram caracterizados por TG, DSC, DMTA, Resistência ao Impacto Charpy, Dureza Shore D. Os resultados obtidos mostraram ser viável a substituição de fenol por lignina em matrizes fenólicas. No entanto, para que se obtenha compósitos com propriedades compatíveis com às exigidas para aplicações industriais, modificações devem ser feitas: modificação de fibras por meio de reações químicas, diversificação do comprimento das fibras vegetais, realização de etapas de cura em temperaturas superiores as consideradas no presente trabalho.

“…Due to their high strength and rigidity combined with low density, fiber-reinforced polymeric composites (FRP) are extensively used in a wide variety of fields, from sports equipment [1][2] to the automotive, civil engineering, [3][4][5] military, [6][7] aeronautics and aerospace [8][9][10] industries. The oldest thermoset polymers are phenolic resins.…”

Phenolic-resin composites have attractive properties for applications in various fields from the wood and adhesive industry to the automotive, aeronautics and aerospace industries. The paper presents the obtaining of SiC-nanofilled phenolic-resin-based composites reinforced with a bidimensional fabric. Different contents of nanometric silicon carbide (0.5, 1 and 2) % mass fractions) were dispersed into the phenolic-resin matrix, using the ultrasonication method, to ensure the optimum dispersion. Several layers of the bidimensional fabric were impregnated with the obtained mixtures and the final laminated composites were obtained using high-temperature pressing, followed by a multistage temperature program. The obtained laminated nanocomposites were characterized with FTIR spectroscopy and evaluated in terms of mechanical and tribological properties. After mechanical testing, fracture cross-sections were characterized with SEM and optical microscopy. The results highlight the positive effect of the nanometric silicon-carbide addition to the phenolic-resin matrix of the laminated composites, in terms of mechanical and tribological performance, improving their strength, stiffness and abrasive properties. Keywords: laminated composites, tensile strength, flexural strength, nanometric silicon carbide, nanocomposites, friction coefficient Kompoziti fenolnih smol imajo mo`nosti raznovrstne uporabe na razli~nih podro~jih, tako na podro~ju lesne industrije, v industriji lepil, kot v avtomobilski in letalski industriji. Prispevek predstavlja pridobitev SiC fenolnih kompozitov na osnovi smole, oja~anih z bidimenzionalnimi vlakni. Razli~ne vsebine nanosilicijevega karbida (0,5, 1 in 2) % masnega odstotka, so bile razpr{ene z uporabo ultrazvo~ne metode v matrici, pridobljeni s smolo, da je bila zagotovljena optimalna disperzija. Ve~plasti bidimenzionalnih vlaken je bilo impregniranih s pridobljenimi me{anicami in kon~ni laminirani kompoziti so bili pridobljeni z visokotemperaturnim tla~nim pritiskanjem, kateremu je sledil ve~stopenjski temperaturni program. Pridobljeni laminirani kompoziti so bili preu~evani s FTIR-spektroskopijo in ovrednoteni glede na mehanske in tribolo{ke lastnosti. Presek zloma po mehanskem testiranju je bil preu~evan s SEM-mikroskopijo in opti~no mikroskopijo. Rezultati ka`ejo pozitiven u~inek dodatka nanometri~nih silicijevih karbidov, s smolo pridobljenih matric v ve~plastnih kompozitih, zaradi njihovih mehanskih in tribolo{kih lastnosti, in ker se tako izbolj{a mo~, togost in abrazivne lastnosti.
