会议名称：The 23rd International Conference on Composite Materials (ICCM23)

会议时间：July 31-August 4, 2023

会议地点：ICC,Belfast, Northern Ireland, UK.

会议简介：The 23rd International Conference on Composites Materials (ICCM 23) will be held in Belfast, Northern Ireland, from July 30th to August 4th 2023. ICCM is the premier international conference in the field of composite materials and was first held in 1975 in the cities of Geneva and Boston. Since that time the conference has been held biennially in North American, European, Asian, Oceanic, and African cities. ICCM 23 will attract the leading researchers and practitioners, to report and exchange ideas on the latest developments in the advancement and exploitation of a wide range of composites materials and structures. The general themes of material development, testing, modelling, manufacturing and design will encompass a breadth of topics which will provide a comprehensive global snap-shot of the state-of-the-art. Plenary and keynote lectures from pre-eminent leaders in the field are planned, along with oral and poster presentations from an expected large delegation coming together in Belfast from all corners of the world. A number of site visits and an entertaining social programme are also planned.

Title: 3D PRINTED CONTINUOUS FIBER REINFORCED COMPOSITES OF ANISOTROPIC TOPOLOGY OPTIMIZED STRUCTURES

Author: Yiming Huang, Xiaoyong Tian,Tengfei Liu, Kai Miao

Abstract: 3D printing of continuous fiber reinforced composites (CFRCs) enables the fabrication of anisotropic topology optimized structures, whose features can simultaneously span the micro fiber trajectory and macro topological morphology. Considering the characteristics of 3D printing, a multiscale design and manufacturing strategy integrating concurrent optimization of fiber orientation and structural topology was developed for CFRCs and realized by ingenious path planning for 3D printing process. Based on this, the fiber content of CFRCs can be progressively designed through finite element analysis (FEA) to maximize load and fiber utilization efficiency of topology optimized structures. By this method, the anisotropic properties of topological CFRPs parts can be fully utilized by curvilinear fiber path, that structural stiffness and peak load could be improved up 36.27% and 64.43% respectively for Messerschmitt-Bölkow-Blohm (MBB) beam, 123.07% and 52.16% respectively for cantilever beam compared to those by straight fiber path. Additionally, the performance of topological CFRPs parts can be further enhanced according to inhomogeneous fiber content, showing 38.55% and 25.40% in structural stiffness and peak load increase compared to the parts with homogeneous fiber contents. Anisotropic topology optimization and 3D printing could promote the potential of CFRCs, and even challenge traditional design and manufacturing mechanism relating material and structure scale.
