Ziqi Wang, Ji Shi, Xiaodong Zhao, Hui Li, Huiming Shen, Jianguo Liang, Jun Feng
TL;DR
This paper presents a cross-scale modeling method for filament-wound composite pressure vessels to balance computational efficiency and accuracy.
Contribution
A novel homogenization method is introduced for cross-scale modeling of CFRP layers in filament-wound vessels.
Findings
The partial homogenization method captures fiber-direction stress distribution in inner layers with 7.56% deviation from detailed models.
Fatigue life analysis shows only 0.28% variation in liner cycles across stacking sequences, indicating minimal impact from homogenization.
The proposed framework effectively balances computational efficiency and accuracy for multiscale simulations of composite vessels.
Abstract
Composite pressure vessels have attracted significant attention in recent years owing to their lightweight characteristics and superior mechanical performance. However, analyzing composite layers remains challenging due to complex filament-winding (FW) pattern structures and the associated high computational costs. This study introduces a homogenization method to achieve cross-scale modeling of carbon fiber-reinforced plastic (CFRP) layers, accounting for both lay-up sequence and in-plane FW diamond-shaped form. The stacking sequence in an FW Type IV composite pressure vessel is numerically investigated through ply modeling and cross-scale homogenization. The composite tank structure, featuring a polyamide PA66 liner, is designed for a working pressure of 70 MPa and comprises 12 helical winding layers and 17 hoop winding layers. An FW cross-undulation representative volume element (RVE)…
