Kevlar fiber bulletproof vest
Kevlar fiber was a material used to make bulletproof vests. It was developed by Dupont in the United States. Bulletproof vests were generally made of Kevlar fiber and ceramic plates, and their toughness was more than five times that of steel. However, due to the heavy weight of Kevlar fiber, the wearer's movements would be restricted. To solve this problem, the researchers developed liquid bulletproof vests, the main component of which was a special shear-thickening liquid (STF). The liquid bulletproof vest was only half the weight of an ordinary bulletproof vest. It was lighter and more practical. The working principle of the liquid bulletproof vest was that when the shrapnel or bullet touched the liquid, the liquid would instantly turn into a hard material, preventing the bullet from passing through. Compared to ordinary bulletproof materials, liquid bulletproof materials were lighter and softer. Therefore, while the Kevlar fiber bulletproof vest provided protection, it also took into account the wearer's comfort and freedom of movement.

Motherboard optical fiber interface
The optical fiber interface was an interface on the main board that could connect the optical fiber directly to the computer. However, the specific use of the optical fiber interface on the main board was not clearly stated. Some of the answers mentioned that the optical fiber interface was used for audio output, such as connecting to a high-end audio amplifier. The other answers indicated that the optical fiber interface was not used to connect to the network cable, but for audio output. In general, the specific use of the optical fiber interface on the motherboards may vary depending on the model and design of the motherboards. Therefore, the search results provided did not provide a clear answer to this question.

Will the glass fiber melt in fire?
Glass fiber would soften at around 600 degrees Celsius. Due to its small diameter, it would shrink into a small bead when softened, while the melting point of rock wool was above 1,000 degrees Celsius. Ordinary lighters could not burn it. The two could be distinguished by this method.
