Abstract

The invention discloses a manufacturing method and device of a distributive optical fiber intelligent CFRP (carbon fiber reinforced plastic) laminated board. A certain load is exerted on a sensing position of an optical fiber sensor; the pre-tightening force is provided for the sensing position of the optical fiber sensor; the optical fiber sensor is put onto the surface of a carbon fiber pre-soaking material according to a preset path, and the condition is maintained until the hot pressing is completed; the uniform stress embedding and encapsulation of the optical fiber sensor is realized. Different wire winding modes are used, so that various different optical fiber sensor laying paths can be effectively planned; high flexibility is realized; the laying requirements of various different paths can be met.

Description

technical field [0001] The invention relates to a method for manufacturing a distributed optical fiber intelligent CFRP laminate and a device thereof. Background technique [0002] Carbon Fiber Reinforced Plastics (CFRP) is light in weight and high in strength, but because the reinforcement and the matrix are mostly formed by layered hot pressing, it is easy to produce defects such as delamination and tearing when subjected to external impact loads or machining. It is a typical brittle and hard material. With the increasing application of CFRP in aircraft, wind energy blades and auto parts, the in-situ real-time monitoring of strain is particularly important and urgent in the optimization research of CFRP components and processing technology. The optical fiber sensor has the characteristics of small size and light weight, and is suitable for embedding inside CFRP to achieve the above monitoring purposes. At present, more carbon fiber composite materials are used to package...
