Final answer:
Aircraft cockpit canopies have been upgraded with polycarbonate material for better protection and visibility. This material is also used in various other products due to its durability and impact resistance. The main polycarbonate is made from bisphenol A and phosgene COCl2.
Step-by-step explanation:
The cockpit canopies of aircraft have been changed to a polycarbonate material that enhances integrity and pilot protection. This material is well-known for its durability, impact resistance, and clarity, making it an ideal choice for applications where safety and visibility are paramount. Among its uses, polycarbonate is also employed in manufacturing beverage bottles, baby milk bottles, unbreakable glazing, and various components in the electronics and automotive industries.
The main polycarbonate material is synthesized through a chemical reaction involving bisphenol A (BPA) and phosgene COCl2. This production process contributes to the material's unique properties that not only benefit cockpits but are also critical to the functionality of other products such as compact discs, electronic apparatus housing, lenses for sunglasses and prescription glasses, automotive headlamps, riot shields, and instrument panels.
