Modeling of Fiber-reinforced Phenolic Foam
A statistical predictive model is developed that describes the compression properties of phenolic foam reinforced with glass fibers. An analysis of variance is applied to determine the behavior of composite phenolic foam. The material variables used in the study are fiber length, fiber weight fraction and weight percentage of blowing agent. The responses analyzed are density, compressive modulu...
متن کاملKinetic Study of Thermal Degradation of a Lignin Nanoparticle-Reinforced Phenolic Foam
In the present study, the kinetics of thermal degradation of a phenolic and lignin reinforced phenolic foams, and the lignin used as reinforcement were studied and the activation energies of their degradation processes were obtained by a DAEM model. The average values for five heating rates of the mean activation energies obtained were: 99.1, 128.2, and 144.0 kJ.mol for the phenolic foam; 109.5...
متن کاملEffect of Hardener on Mechanical Properties of Carbon Fibre Reinforced Phenolic Resin Composites
In this paper the effect of hardener on mechanical properties of carbon reinforced phenolic resin composites is investigated. Carbon fibre is one of the most useful reinforcement materials in composites, its major use being the manufacture of components in the aerospace, automotive, and leisure industries. In this study, carbon fibres are hot pressed with phenolic resin with various percentages...

متن کاملNanoparticle-reinforced resin-based dental composites.
OBJECTIVE TiO(2) nanoparticles treated with the organosilane allyltriethoxysilane (ATES) are used to improve the mechanical properties of dental resin-based composites (RBCs, Z100, 3M ESPE). METHODS TiO(2) nanoparticles were sonically dispersed in an ethanol solution containing ATES. The modified particles were washed in pure ethanol and dried before being used as filler. Fourier transform in...
