(a) Create a list of the required properties of thematerials to be selected in the design and manufacturing of a large travelsuitcase. (b) Propose a number of candidate materials. (c) Identify your bestchoice and explain why? Lightweight : The material should be lightweight to avoid adding extra weight for travelers, ensuring ease of handling and compliance with airline weight limits. Durability : The suitcase must withstand rough handling, including impacts, drops, and abrasion. Resistance to cracking and deformation is important for long-lasting use. Impact Resistance : Suitcases often endure significant impact, especially during air travel, so the material should be capable of absorbing shocks without cracking or breaking. Water Resistance : To protect the contents from rain or accidental spills, the material should have good water resistance or be waterproof. Scratch and Abrasion Resistance : The material should resist scratches and abrasions from rough surfaces, keeping the suitcase looking good over time. Toughness : The material needs to withstand repeated stresses without breaking or wearing out easily. Flexibility : While durability is key, some flexibility is needed so the suitcase can absorb stresses and deformations without damage. Thermal Stability : The material should remain stable in varying temperatures, particularly during travel in different climates or storage in airplane cargo holds. Cost-effectiveness : The material should be affordable, allowing the suitcase to be manufactured at a competitive price. Aesthetic Appearance : The material should allow for attractive design finishes, as style is an important consideration for many buyers. Chemical Resistance : The suitcase material should be resistant to common chemicals, oils, and cleaning agents. Ease of Manufacture : The material should be easy to mold, cut, or shape into the required suitcase form, allowing for efficient production processes. (b) Candidate Materials for aLarge Travel Suitcase Polycarbonate (PC) : Properties: Lightweight, high impact resistance, scratch-resistant, water-resistant, and flexible. Applications: Frequently used for hard-shell suitcases due to its excellent toughness and resilience. ABS (Acrylonitrile Butadiene Styrene) : Properties: Durable, lightweight, moderately impact-resistant, cost-effective, and easy to mold. Applications: Commonly used in mid-range hard-shell suitcases, offering a balance between durability and affordability. Nylon : Properties: Lightweight, flexible, strong, water-resistant, and abrasion-resistant. Applications: Often used for soft-sided luggage due to its flexibility and strength. Polyester : Properties: Lightweight, flexible, affordable, water-resistant, and durable. Applications: Used in soft-sided suitcases, offering a budget-friendly option with decent performance. Aluminum : Properties: Very strong, impact-resistant, durable, and rigid. Applications: High-end, luxury suitcases due to its strength and premium appearance, though it tends to be heavier and more expensive. Polypropylene (PP) : Properties: Lightweight, flexible, impact-resistant, water-resistant, and affordable. Applications: Used for hard-shell cases that need to be durable but cost-effective. (c) Best Choice andJustification Best Choice: Polycarbonate(PC) Reasons: Excellent Impact Resistance : Polycarbonate is one of the most impact-resistant plastics, making it ideal for withstanding the rough handling common during travel. Lightweight : It strikes a good balance between durability and weight, ensuring that the suitcase is easy to carry while providing maximum protection for the contents. Scratch and Abrasion Resistance : Polycarbonate surfaces can be made scratch-resistant, ensuring that the suitcase maintains a good appearance over time. Waterproof : Polycarbonate is inherently waterproof, ensuring that the contents of the suitcase are protected from rain or spills. Flexibility and Durability : Unlike more rigid materials like aluminum, polycarbonate has some flexibility, allowing it to absorb shocks without cracking. Aesthetic Versatility : Polycarbonate can be molded into various shapes and designs, allowing for stylish and modern suitcase designs. Thermal and Chemical Stability : It performs well across different temperatures and is resistant to most chemicals, which is important for the diverse environments a suitcase encounters. While ABS and polypropylene are cost-effective alterna
