Problems solved by technology

The dielectric analyzer uses the change of the ionic conductivity of the resin itself during the curing reaction to change its dielectric properties. By monitoring the change of the dielectric properties during the curing process, the temperature change during the curing process can be inferred, but the The method needs to modify the mold, and the cost is relatively high

Description

technical field [0001] This document relates to the technical field of distributed optical fiber sensing, and in particular, to a method and device for visual monitoring of temperature in the preparation of distributed optical fiber-embedded leaf springs. Background technique [0002] In recent years, with the development of advanced material science and composite material molding technology, fiber-reinforced composite materials are gradually replacing metal materials in some fields due to their high strength, light weight, fatigue resistance, easy automatic mass production, and easy modeling. , composite materials are known as the most promising materials in the 21st century. The leaf spring is an important part of the automobile suspension system, which plays the role of bearing pressure, shock absorption and buffering, and guiding during the driving process of the automobile. In the past, automobile leaf springs were generally made of alloy steel. The leaf springs made o...
