glass fiber

PCBs -- which house and interconnect chips, transistors and other components -- typically consist of layers of thin glass fiber sheets coated in hard plastic and laminated together with copper.

A similar incident happened in 2017, when a glass fiber broke, causing delays.

Each of its 40-kilogram mirrors hangs from a pair of thin glass fibers.

Lava flowing from the volcano was confined to the summit area, but officials warned that winds could carry volcanic gas, fine ash and thin glass fibers known as Pele’s hair downwind.

Next, the researchers used vacuum pressure to pull the resin through glass fibers.
