Titanium (Ti) has been widely used in many fields such as aerospace, automotive, engineering and medical. The main properties of Ti are high strength, low density, and excellent corrosion resistance influence their value. These properties make them very attractive for a variety of applications. Ti alloys provide structural materials in the aeronautics and astronautics industries because of their high specific strength but they are expensive. Stainless steel is a widely used and it is an inexpensive

The term "prepreg" is actually an abbreviation for the phrase pre-impregnated. A prepreg is a fiber reinforced and pre-impregnated with a resin, most commonly consists of a fabric (Carbon, Kevlar, Glass, etc.) impregnated with a resin maintained in a pre-gelled condition. The primary resin matrix used is epoxy. However, other thermoset resins are made into prepregs including BMI and phenolic resins. Carbon fiber is first developed in 1958 in Cleveland, OH, by heating rayon strands which was of relatively

products. It’s found in plastic bottles, sippy cups, food cans, medical devices, DVDs, etc. This chemical is a colorless, crystalline solid, organic compound that hardens plastic during manufacturing. As for the environment, there isn’t much controversy; BPA rapidly biodegrades in the environment. There are no adverse environment effects, but there is a problem with this chemical that lies somewhere else. Exposure to humans results from the use of plastics, BPA gets off from the plastic or the coating of

A world full of different types of materials- not the fabric materials you buy at spotlight, but the numerous materials used to build houses, construct roads and even make up the air that we breathe. Materials are all around us. Have you ever wondered why salt can be crushed so easily, or why water has such a low melting point? This is due to the chemical properties of the materials and what they are made of! Everything in the world is made up of atoms. Atoms are the smallest forms of matter. What

In this lab the results for part A demonstrated that the different plastics have different properties. When it came to test for density, the densest was PETE. Polyethylene Terephthalate was shown to be denser than water and alcohol. The two least dense plastics that were tested were PS and the unknown plastic. Both the Polystyrene and unknown did not sink in either the water or alcohol mixture. HDPE and LDPE were both less dense than the water but denser than the alcohol-water solution. When it came

Epoxy is a substance that is formed from two liquid components; a hardener and a resin. When they are mixed, they begin the curing process, its’ end product is a solid and permanent bond. They form an adhesive, glue, filler, paint or other material made from synthetic thermosetting polymers that contain epoxide groups. Epoxy is made from epichlorohydrin and bisphenol-A. Then it is mixed with a hardening agent to make it stronger. When they are mixed, they make a polymerize, which is a long chain
