Comparison of Analytical Model of Springback Angle of Composite Plate with Measurement with and without Recrystallization Effect

Abstract

Presented paper deals with comparison of two measurements done in our lab to achieve the value of the springback angle of composite plate with single curvature. Plate consists of carbon fiber and PPS matrix. Springback angle without recrystallization effect was measured earlier with the use of laser profilometer ScanControl LLT 2800-25 and optical distance measurement CHRocodile M4. Springback angle with recrystallization effect was measured later with the use of Fibre Bragg Grating optical sensor (FBG) and image processing. Results were compared with an analytical solution in developed software “Springback” with achieving good agreements.
