Plastic: A versatile Material with Environmental Concerns

 What is Plastic? Plastic is a synthetic or semi-synthetic material made up of organic polymers of high molecular mass. It is known for its versatility, durability, and low cost, making it a ubiquitous material in modern life. Invention of Plastic The invention of plastic is a bit of a complex story with multiple key figures: Alexander Parkes: In 1862, Parks created Parkesine , considered  the first man-made plastic. It was derived from organic cellulose and could be molded into various shapes. John Wesley Hyatt: In   1868, Hyatt developed Celluloid , a modification of Parkesine. Celluloid became popular for its use in photographic film and as a substitute for ivory.. Leo Baekeland: In 1907, Baekeland invented Bakelite , the first fully synthetic plastic. It was made from combining phenol and formaldehyde and was highly heat resistant and moldable. Bakelite revolutionized the plastic industry. So, while Parkes is often credited with the first man-made plastic, Bakeland'...

Aircraft Tires and Features

Aircraft tires are specially designed to withstand the extreme loads and speeds encountered during take-off, landing and taxiing. They are typically made of high-strength rubber compounds reinforced with steel cords or Kevlar. Key Features of Aircraft Tires High Load Capacity: Aircraft tires must be able to support the enormous weight of the aircraft during take-off and landing. High Speed Capability: They must be able to withstand the high speeds reached during take-off and landing without overheating or bursting. Retreadability: Many aircraft tires are designed to retreaded multiple times, which helps to reduce costs and environmental impact. Heat Resistance: Aircraft tires operate at high temperatures, especially during braking, and must be able to dissipate heat effectively to prevent failure. Cut and Chip Resistance: The tread must be resistant to cuts and chips from runway debris. Hydroplaning Resistance: The tread pattern must be designed to channel water away from the tire cont...
