COMPOSITES & MECHANISM
Introduction
 Composite materials have been used throughout history
– ancient building material
– straw/mud huts still used today
 The human body relies on a natural composite
– bone
– hard brittle hydroxyapatite and soft protein collagen
 Wood is also a natural composite
– strong and flexible cellulose fibres are surrounded by lignin matrix
 The use of modern composites allows us toproduce materials with unusual comb ....etc

ARE NATURAL FIBER COMPOSITES ENVIRONMENTALLY SUPERIOR TO GLASS FIBER REINFORCED COMPOSITES?
INTRODUCTION:-
• Natural fibers have been used to reinforce materials for
over 3,000 years.
• Many types of natural fibers have been investigated for
use in plastics .including , Flax, hemp, jute, straw,
wood fiber, rice husks,wheat,barley,oats .
• Natural fibers have the advantage that they are
renewable resources and have marketing appeal.
• Natural fibers are increasingly used in automotive a ....etc

Design and Fabrication of Artifically Engineered Material Composites for Electromagnetic Systems


While the number of advanced devices designed for the wireless communication industry increases significantly, their sophistication in terms of technology, level of integration, and miniaturization increases as well. Concurrently, cost, size, and performance expectations become more and more stringent, necessitating advanced system architectures, 'new' materials and versatile design optimization procedures. The capability to manipulate the dist ....etc

COMPOSITES - INTRODUCTION
Composite materials are those that are formed by the combination of two or more materials to achieve properties that are superior to those of its constituents.
Composites could be
• Natural
• Synthetic.
Bamboo is a very good example of efficient Natural Composite. The components are cellulose and lignin, as in all other wood, however bamboo is hollow. This results in a very light yet stiff structure.
Centuries ago people used to use co ....etc

Abstract:
Dental Composites to Degraded MLI:


Ben Reed's experience as a materials engineer has led him from the challenges of dental composites to long term space exposure on the Hubble Space Telescope (HST).

Dental composites were developed in the 1960s and have continued to play a major role in restorative dentistry to date. However, they do not exhibit the typical service life of silver amalgam or gold fillings. Much of their lower service life is due to the consequences of polymerization shrinkage.

The Hu ....etc

Composites materials for aerospace applications
Abstract:
Fibre-reinforced polymer composite materials are fast gaining ground as preferred materials for construction of aircrafts and spacecrafts. In particular, their use as primary structural materials in recent years in several technology-demonstrator front-line aerospace projects world-wide has provided confidence leading to their acceptance as prime materials for aerospace vehicles. This paper gives a review of some of these developments with a discussion of the proble ....etc

this seminar describes steps involved in the manufacturing process of semicrystalline thermoplastic matrix composites. The model relates the temperature and pressure applied during processing to a) the flow of the matrix into the fiber tow, b) the formation of contact and bond between adjacent plies, and c) the crystallinity. The results of the model were verified by tests performed with PEEK 150P polymer and APC-2 graphite/PEEK composite. ....etc
