Numerical Study of Tensile Properties of POM/ Woven Kenaf Composite.

CHAPTER 1:
INTRODUCTION

1.1 Background Study
The geometry of woven fiber reinforced polymer like Polyoxymethylene (POM) and Woven Kenaf composite is quite complex. Therefore, to predict tensile properties of such composite requires numerical method. This project focuses on the use of The Laminator software and understanding the theories on Maximum Stress, Maximum Strain, Tsai-Hill, Hoffman, and Tsai-Wu failure to produces the required results. The software will be used to analyze the tensile strength and modulus of the composite. The results obtained from the study will then be used to compare and validate through experiment done by other researcher. Successful implementation of this numerical study will allow the tensile properties analysis to be conducted confidently without being too dependent on experimental work which is time and cost consuming.

1.2 Problem Statement
Experimental study of tensile properties on polymer/ woven fiber composite was done by Yakubu et al. [1] and other researchers [2, 3]. However effort on predicting tensile properties of woven fiber reinforced polymer is very limited. Therefore, this project is proposed. By using numerical study we can predict the tensile properties of the composite to be used in industry. This study can be used as a benchmarks before carry out the actual tests and experiments.

1.3 Objective
The objective of this project are:
To predict tensile strength and modulus of POM/ Woven Kenaf composite using numerical method.
To validate the numerical data with current experimental result.

1.4 Scope of Study
In this study, polyoxymethylene (POM) was used as the matrix and Kenaf was employed...

- The discovery and widespread usage of composite materials has opened new doors in the manufacturing industry. Composites are materials composed of two or more different materials. The new material has distinct and superior structural properties than the individual component materials. The most ancient composite is adobe, which consists of straw reinforced clay and was commonly used as a building material [1]. Modern composites consist of a woven fiber, which reinforces a plastic polymer shell. Two major examples of modern composites are fiberglass and carbon fiber....   [tags: Carbon fiber, Composite material, Boeing 787]

## Experimental and numerical study on the Effect of Mixture Composition on Vented Explosions

- A parametric set of vented explosion experiments for three mixtures, stoichiometric propane-air, methane-air and 18.0 vol. % hydrogen-air were performed. The three mixtures each displayed various physical phenomena and behaviors and their similarities and differences were identified. A physics based CFD model was developed, using a small subset of the experimental data, with a single set of empirical coefficients for all three mixtures. The model takes into account the effect of turbulence, flame instabilities and the Rayleigh-Taylor instability on flame propagation and pressure generation....   [tags: Physics]

## Numerical concepts Essay

- Imagine you are sitting in your office when a little child comes bouncing in to the room, filled with curiosity. They look around the room and begin to question everything they see before their eyes fall on a large bookshelf against the wall. The little child looks at the shelf in awe, and exclaims “There must be a million books there!” Most of us who have spent time with a little kid at some point have probably heard them over exaggerate when it comes to guessing the amount of something, but not all of us have considered why this might be....   [tags: Estimating Stimuli, Mathematical Cognition]

## Continuum Percolation Study of Carbon Nano Tube Composites via Size Distribution Effects

- Continuum Percolation Study of Carbon Nano Tube Composites via Size Distribution Effects The three-dimensional continuum percolation problem of hard-core and soft-core (permeable) objects was an area of active research in the 1980s[1]. Among the considered geometrical objects a very important category is the case of permeable sticks with the form of capped cylinders [2]. Advancements in capabilities of theories and numerical studies has lead to recent developments of polymer reinforced nanocomposites which overcome the need for having certain combination of electrical and mechanical properties [4]....   [tags: Percolation Study Lab]

## Musing of a Woven Plotline Essay

- Just as the fates, woven throughout both Greek and roman mythology, asserted fear through their weaving, measuring, and cutting, Dickens has used Madame Defarge to spread fear among the citizens. Throughout A Tale of Two Cities Madame Defarge knits, her very presence dominating the scenes and controlling the plot of the entire novel. She presides over everyone, her aura of authority, judgment, death, and destruction maintains a stony reign over those who come near her. The knitting throughout the novel signifies a deeper meaning, and forecasts the mood of the time period....   [tags: Literary Analysis]

## The Causes and Effects of Micro-leakage in Posterior Composite Restorations

- BACKGROUND Composite restoration usage in dentistry is increasing. Because of this interest in the longevity and reliability of composite fillings also is increasing1. One problem that can occur with composite restorations is micro-leakage. This is when microgaps at the tooth-restoration interface allow fluids and bacteria into the restoration2. These gaps are formed when the material is polymerized and shrinks, which causes the material to pull away from the margins of the preporation2. Problems that can arise from micro-leakage are secondary carries, hypersensitivity, pulp stimulation, and marginal discoloration3....   [tags: dentistry, dental health]

- In a composite material the constituents are arranged generally with the reinforcement phase embedded in the matrix phase. Due to a composite being essentially a mixture between the reinforcement phase and the matrix there is no intermolecular bonding between the two, however, as in the case of fibrous composites, the most mechanically efficient structure is a criss-crossed fibrous lattice suspended in a material matrix. In the case of particulate composites however, the reinforcement phase acts essentially to strengthen the matrix material adding support....   [tags: Scientific Research ]

## COMPOSITE MATERIALS Essay

- The word composite comes from the latin “composititus” meaning made up of distinct parts. A composite material is a material composed of two or more distinct materials[1], or constituents, with one constituent acting as the reinforcing phase and the other as the matrix[6]. A composite material is defined by having different macroscopic behaviours, or chemical and physical properties then its constituent materials, and has a distinct interface boundary on the microscopic level[5].
