Full-scale multi-physics numerical analysis of an isothermal chemical vapor infiltration process for manufacturing C/C composites

Autor: Hyang Joo Kwon, Sungtae Yoon, Wooseok Ji, Jung-il Kim, Hye-gyu Kim, Nam Choon Cho, Soobin Bae

Publikováno v: Carbon. 172:174-188

The internal architecture of a CVI reactor significantly influences the gas flow behavior, as well as the complex time-varying chemical reactions, but has been typically ignored in previous CVI models. Herein we developed, validated, and applied a fu

Deformation and interlaminar crack propagation sensing in carbon fiber composites using electrical resistance measurement

Autor: Eonyeon Jo, Hye-gyu Kim, Sooyoung Lee, Hyung Doh Roh, Wooseok Ji, Young-Bin Park

Publikováno v: Composite Structures. 216:142-150

In this study, we propose analytical and experimental methods to predict and detect deformation and interlaminar crack propagation in carbon fiber-reinforced plastics (CFRPs) based on electrical resistance measurement. The electromechanical behavior

Thermal conductivity of a thick 3D textile composite using an RVE model with specialized thermal periodic boundary conditions

Autor: Wooseok Ji, Hye-gyu Kim

Publikováno v: Functional Composites and Structures. 3:015002

Finite element analysis is performed to virtually measure homogenized thermal conductivity of a thick 3D woven textile composite (T3DWC). Temperature-dependent thermal and mechanical properties of constituents are considered for the measurements over

CSAI analysis of non-crimp fabric cross-ply laminate manufactured through wet compression molding process

Autor: Wooseok Ji, Sooyoung Lee, Hye-gyu Kim, Seong-Woo Im, Taeseong Choi, Young-Bin Park, Soo-Chang Kang, Chaeyoung Hong

Publikováno v: Composite Structures. 255:113056

The main purpose of the present work is to demonstrate mechanical performance of a wet-compression-molding (WCM) composite product through conventional compressive-strength-after-impact (CSAI) analysis. Biaxial non-crimp fabric (NCF) is utilized to m
