Why should plastic material be reinforced with glass fiber?
Its plastic is fragile, in order to resist wrestling, compression, increase strength and toughness. It's just like adding steel to a concrete slab. The casing of a notebook usually adds fiber.
Increase strength and toughness, plastic is plastic, after all, many properties can not keep up, just like building a house, why does it add rebar?
Some physical properties of plastics is generally lower than that of metals, glass fiber can improve the plastic modulus, can also improve the plastic temperature resistance, but after the addition of glass fiber, plastic will become more brittle toughness.
