That's the thinking the article is arguing against.
But I do have an example.
High end polycarbonate prescription lenses for glasses.
The high index, thinnest, lightest lenses, are plastic. Not glass.
Edit: Thinking more, I wonder how much more expensive it would be to use the same polycarbonate material on phones.
It would certainly be stronger and less prone to breaking. With good coatings, it would be just as scratch resistant.
It would offer the same premium look and similar feel as glass. Just lighter.
How is that not plastic?
Carbon fibre without plastic is just a hairy string
And with silicone I don't even understand where the confusion is coming from? What else would it be?
You sent me down a bit of a rabbit hole and now I'm less sure of what plastic actually is. Epoxy, which is used for carbon fiber among many, many, many other things, isn't something I'd say is plastic but I looked it up and it was about 50/50 on plastic vs not. I found similar conflicting information about silicone but it was leaning more toward not being a plastic.
Plastics are a wide range of synthetic or semi-synthetic materials that use polymers as a main ingredient. - Wikipedia
: a plastic substance
specifically : any of numerous organic synthetic or processed materials that are mostly thermoplastic or thermosetting polymers of high molecular weight and that can be made into objects, films, or filaments -Merriam Webster
plastic, polymeric material that has the capability of being molded or shaped, usually by the application of heat and pressure. This property of plasticity, often found in combination with other special properties such as low density, low electrical conductivity, transparency, and toughness, allows plastics to be made into a great variety of products. These include tough and lightweight beverage bottles made of polyethylene terephthalate (PET), flexible garden hoses made of polyvinyl chloride (PVC), insulating food containers made of foamed polystyrene, and shatterproof windows made of polymethyl methacrylate. -Brittanica
Composites like CF and fiberglass use those materials as a stress distributing component and a plastic component as the rigid layer.
Historically fiberglass composites used things like polyester resin - a polymer derived from oil - as the rigid component.
So your idea of premium is fragile and expensive?
Plastic has superior usability in every way, weight, bulk, durability, shock absorption, less slippery than glass, meaning it doesn't drop out of pockets handbags or even hands as easily.
So what part about a high end plastic is that isn't premium in this situation?
Which is a problem of perception and marketing, given that in many cases a plastic that has been specifically engineered to perform a function will, unsurprisingly, be better than an alternative.
