What Grounds Jets? Brake Discs & Retraction Actuators Under Fire

/ 11 minutes of reading / By / ,

The core causes of frequent groundings of jet aircraft are the thermal decay effect of brake discs and hydraulic hysteresis of retraction actuators: Emirates Boeing 777 failed due to delamination of carbon fiber brake discs at 1200℃ (NTSB report AAR-24/01), exposing the thermal resistance limit of traditional materials; Airbus A320neo fleet caused a 300% surge in the risk of landing

What is the difference between PVA and HIPS?

/ 11 minutes of reading / By /

In the field of 3D printing, PVA and HIPS are two mainstream support materials with significant differences: PVA (polyvinyl alcohol) is a water-soluble material, especially suitable for use with low-temperature consumables such as PLA, which dissolves quickly, is environmentally friendly and easy to operate; while HIPS (high-impact polystyrene) needs to be dissolved with limonene solvent.
