Identification of mechanical parameters of fiber-reinforced composites by frequency response function approximation method

Mechanical Properties of SiC Fiber- Reinforced Reaction-Bonded Si3N4 Composites

Mechanical properties of woven glass fiber-reinforced composites.

The aim of this investigation was to measure the flexural and compressive strengths and the corresponding moduli of cylindrical composite specimens reinforced with woven glass fiber. Test specimens were made by light-curing urethane dimethacrylate oligomer with woven glass fiber of 0.18-mm standard thickness. Tests were conducted using four reinforcement methods and two specimen diameters. Flex...

MECHANICAL CHARACTERIZATION AND ANALYSIS OF RANDOMLY DISTRIBUTED SHORT BANANA FIBER REINFORCED EPOXY COMPOSITES

Short banana fiber reinforced composites have been prepared in laboratory to determine mechanical properties. It has been observed that as soon as the percentage of the banana fiber increases slightly there is a tremendous increase in ultimate tensile strength, % of strain and young modulus of elasticity. Reinforcement of banana fibers in epoxy resin increases stiffness and decreases damping pr...

Compressive response and failure of fiber reinforced unidirectional composites

The compressive response of polymer matrix fiber reinforced unidirectional composites (PMC’s) is investigated via a combination of experiment and analysis. The study accounts for the nonlinear constitutive response of the polymer matrix material and examines the effect of fiber geometric imperfections, fiber mechanical properties and fiber volume fraction on the measured compressive strength an...

Response of fiber reinforced composites to underwater explosive loads

An in-house developed, verified and fully validated three-dimensional finite element code, with rate dependent damage evolution equations for anisotropic bodies, is used to numerically ascertain the damage developed in a fiber-reinforced composite due to shock loads representative of those produced by an underwater explosion. Three internal variables characterize damage due to fiber/matrix debo...
