Distribution of Residual Stresses in Polymer Reinforced Carbon Nanotubes and Laminated Carbon Fibers
In this study, the distribution of residual stress in fiber-reinforced nanocomposites is investigated. Fiber-reinforced nanocomposite is composed of three substances: carbon fiber, carbon nanotube (CNT), and polymer matrix. Unit cells in hexagonal packing array with different arrays as unit cell, 3*3 and 5*5 arrays have been selected as suitable for finite element analysis of residual stresses....
full textresidual stresses in thermoplastic composites: a review
applications of thermoplastic composites have developed extensively. the thermoplastic composites in comparison with the thermoset composites have many advantages. thermoplastic composites can be melted and remolded many times. the duration of manufacturing process of these composites is short, producing very tough material, and the welding ability and multiple recyclings are their further adva...
full textA Modelling Approach for Predicting Residual Stresses and Distortions in Polymer Composites
High dimensional variability is inherent in the manufacture of fibre-reinforced composite components. In the aerospace industry, this stems largely from the elevated temperatures needed to process the composite materials, which give rise to residual, or frozen-in, stresses; these are exacerbated by chemical shrinkage of the resin during cure. These stresses can subsequently cause distortion and...
full textFracture Mechanics of Composites with Residual Thermal Stresses
The problem of calculating the energy release rate for crack growth in an arbitrary composite in the presence of residual stresses is considered. First, a general expression is given for arbitrary, mixed traction and displacement boundary conditions. This general result is then applied to a series of specific problems including statistically homogeneous composites under traction or displacement...
full textResidual Stresses in Tungsten / Bulk Metallic Glass Composites
Bulk metallic glasses (BMGs) have recently gained popularity due to the development of new alloys that yield a glassy structure even with “conventional” metal processing such as casting. The unique properties of BMGs potentially place them among significant engineering materials: very high strength (1.9 GPa) and fracture toughness (40-55 MPa.m), a near theoretical specific strength, excellent w...
full textApplication of Pulse Method to Incremental Slitting Measurement of Residual Stresses in Laminated Composites
In this research, the incremental slitting method was employed to determine throughthickness residual stress profile of a carbon/epoxy laminate. The method involves measuring strains at the back surface of the stressed specimen, while a narrow slit is cut by a CNC milling machine progressively from the top surface of the specimen. "Pulse Method" was selected as the computational approach for th...
