An Influence of Temperature on Additive Manufactured Composite with Embedded Fiber Bragg Grating Sensor

Abstract

Additive manufacturing (AM) is a name for techniques applied to constructing threedimensional (3D) objects in a layer-by-layer process. AM methods can be applied for creating elements from fiber (glass/ carbon) reinforced polymers. During the process, fiber Bragg grating (FBG) sensors can be embedded into the element structure for the purpose of structural health monitoring (SHM) system development. Such an approach combines in one, advantages of AM (limited waste, elements with complex shape) and SHM system (safety, information about real loading conditions). Such a method can be applied for the manufacturing of different elements applied in many branches of industry, e.g. marine or civil engineering. The goal of the paper is to analyze the temperature influence on AM fiber (glass/ carbon) reinforced polymer structures with embedded FBG sensors. The analyzes will be focused on the influence of FBG sensors on material durability. Additionally, the influence of elevated temperatures on the finished AM elements will be investigated.
