2. Polycarbonate - Wikipedia

   en.wikipedia.org/wiki/Polycarbonate

   Polycarbonate. Polycarbonates (PC) are a group of thermoplastic polymers containing carbonate groups in their chemical structures. Polycarbonates used in engineering are strong, tough materials, and some grades are optically transparent. They are easily worked, molded, and thermoformed. Because of these properties, polycarbonates find many ...

3. Poly(methyl methacrylate) - Wikipedia

   en.wikipedia.org/wiki/Poly(methyl_methacrylate)

   Poly (methyl methacrylate) (PMMA) is the synthetic polymer derived from methyl methacrylate. It is used as an engineering plastic, and it is a transparent thermoplastic. PMMA is also known as acrylic, acrylic glass, as well as by the trade names and brands Crylux, Hesalite, Plexiglas, Acrylite, Lucite, and Perspex, among several others (see below).

4. Twinwall plastic - Wikipedia

   en.wikipedia.org/wiki/Twinwall_plastic

   6mm Twinwall Polycarbonate Sheet. Twin-wall plastic, specifically twin-wall polycarbonate, is an extruded multi-wall polymer product created for applications where its strength, thermally insulative properties, and moderate cost are ideal. [1] Polycarbonate, which is most commonly formed through the reaction of Bisphenol A and Carbonyl Chloride ...

5. List of refractive indices - Wikipedia

   en.wikipedia.org/wiki/List_of_refractive_indices

   List of refractive indices. Refraction at interface. Many materials have a well-characterized refractive index, but these indices often depend strongly upon the frequency of light, causing optical dispersion. Standard refractive index measurements are taken at the "yellow doublet" sodium D line, with a wavelength (λ) of 589 nanometers.

6. Polycarbonate (functional group) - Wikipedia

   en.wikipedia.org/wiki/Polycarbonate_(functional...

   Polycarbonate (functional group) A polycarbonate is an oxocarbon dianion consisting of a chain of carbonate units, where successive carbonyl groups are directly linked to each other by shared additional oxygen atoms. That is, they are the conjugate bases of polycarbonic acids, the conceptual anhydrides of carbonic acid , or polymers of carbon ...

7. Carbon-fiber reinforced polymer - Wikipedia

   en.wikipedia.org/wiki/Carbon-fiber_reinforced...

   The properties of a CFRP depend on the layouts of the carbon fiber and the proportion of the carbon fibers relative to the polymer. [6] The two different equations governing the net elastic modulus of composite materials using the properties of the carbon fibers and the polymer matrix can also be applied to carbon fiber reinforced plastics.
