You are to manufacture a smart phone case, material selection question below:

Speicfy the details of the EXACT material grade selected for each of the three material variations of the smart phone case; one metal, one polymer and one carbon-fibre composite (specify the resin type).

- What would be the best choice of material for the phone case from the three options?

Expert Solution

The materials best for design of a smart phone back plate cover are as follows:

1. Metal- Alluminium alloy

2. Polymer- polypropylene

3. Carbon fiber- Polycarbonate

Exact material grade:

1.Alluminium alloy: Al7075

Formiability is good that it can be used to form any shape.

Light in weight

2 Polypropylene: HM012T Injectin molding polypropylene

readily available

high flexural strength

very resistance to absorbing moisture

Good electrical resistance

Resin type-Thermoplastic

3.Carbon Fiber: Polycarbonate (Lexan - comon trade name)

Suitable for screen printing

resistant to fluctuating temperature

can be thermofromed easily

Resin type - Epoxy resin

Out of three Plyvarbonate is best for mobile back plate cover, because wear resistance and flammability grade is UL94 which means optical electrical insulation.Cell phone cases feel smooth, hard or soft.
