Research on CFRP Periscope Outer Tube

Abstract

According to the structure and mechanical characteristics, a CFRP (carbon fiber reinforced plastic) periscope outer tube was designed. The parameters were determined such as fiber orientation angles, number of layers, proportion of fiber with different angles, and stacking sequences. A finite element model was built for the analysis of bending strength and modal. A CFRP periscope outer tube specimen was processed for the bending performance test. The results of simulation and experiments show that the CFRP periscope outer tube could meet the requirements.
