Thermal shock on interfacial adhesion of thermally conditioned Glass fiber/epoxy


The fiber/matrix adhesion is most likely to control the overall mechanical behavior of fiber-reinforced composites. An interfacial reaction may result in various morphological modifications to polymer matrix microstructure in proximity to the fiber surface. The interactions between fiber and polymer matrix during thermal conditioning and thermal shock are important phenomena.

Thermal stresses were built-up in glass ....etc

Abstract
The possibility of using finely ground waste glass as partial cement replacement in concrete was examined through three sets of tests: the lime-glass tests to assess the pozzolanic activity of ground glass, the compressive strength tests of concrete having 30% cement re-placed by ground glass to monitor the strength development, and the mortar bar tests to study the potential expansion. The results showed that ground glass having a particle size finer than 38 m did exhibit a pozzolanic behavior. A size effect was observed; ....etc

Over the last decade, particle tracking microrheology has matured as a new tool for complex fluids research. The main advantages of microrheology over traditional macroscopic rheometry are: the required sample size is extremely small (~ 1 mL); local viscoelastic properties in a sample can be probed with high spatial resolution (~1-10 mm); and the sample is not disturbed by moving rheometer parts. I will present two examples of recent work in my group that highlight how these characteristics can be exploited to acquire unique information about t ....etc

SURFACE COMPUTER



INTRODUCTION

Surface computing is the term for the use of a specialized computer GUI in which
traditional GUI elements are replaced by intuitive, everyday objects. Instead of a
keyboard and mouse, the user interacts directly with a touch-sensitive screen.It is a
natural user interface.
Surface computer was created by Microsoft with surface(code named Milan)
The Surface is a horizontal display on a table-like form.A surface computer is a computer
that interacts with the user through t ....etc

The effect of sub surface defects in surface roughness monitoring through ultrasonic flaw detector.
Objective
 To study the effect of sub surface defects in surface roughness monitoring through ultrasonic flaw detector.
 To study the sizing of defects.
Ultrasound Concepts
• All sound waves, whether audible or ultrasonic, are mechanical vibrations involving movement of the medium in which they are traveling. A sound wave may be transmitted through any material which behaves in an elastic manner.

xperimental results on ?ber micro-buckling of continuous glass-?ber reinforced hollow-cored recycled plastic extrusions under creep tests are introduced. The full size specimens with dimensions in 2:5 Â 3:5 Â 42 in:3 were submerged in warm water at a temperature of 125 °F when they were under a four-point bending creep test. The results show that the micro-buckling of the embedded glass-?ber roving occurs along 90% the length of the specimen on the upper inner surface (compressive side) and mainly during the time bet ....etc
