Abstract

A pin-slot positioning method was proposed to fabricate carbon fiber reinforced polymer (CFRP) metamaterials of hexagonal and zero Poisson's ratio semi-re-entrant honeycombs with the same mass of monolayer continuous twill-woven carbon fiber/epoxy prepregs. The in-plane compressive collapse of CFRP honeycombs was explored through experiments and finite element (FE) simulations. Furthermore, analytical models were developed to predict the modulus and initial collapse stress of the hexagonal and semi-re-entrant honeycombs. Good agreement is achieved between analytical predictions, FE simulations and experimental results. It is shown that the initial collapse of CFRP honeycombs is by the bending of cell walls. Once initial collapse has been attained, both hexagonal and semi-re-entrant honeycombs have a stress softening. The collapse and failure modes of CFRP honeycombs strongly depend on cellular configurations and loading directions.

CFRP 蜂窝超材料的制作和平面内压缩塌陷
研究人员提出了一种针槽定位方法,利用相同质量的单层连续斜纹编织碳纤维/环氧树脂预浸料,制造出六边形和零泊松比半重向蜂窝的碳纤维增强聚合物(CFRP)超材料。通过实验和有限元(FE)模拟探讨了 CFRP 蜂窝的面内压缩塌陷。此外,还建立了分析模型来预测六角形和半重向蜂窝的模量和初始塌陷应力。分析预测、有限元模拟和实验结果之间取得了良好的一致性。研究表明,CFRP 蜂窝的初始坍塌是由蜂窝壁的弯曲造成的。一旦达到初始坍塌,六角形和半内凹蜂窝都会出现应力软化。CFRP 蜂窝的坍塌和破坏模式在很大程度上取决于蜂窝结构和加载方向。

期刊介绍: Composites Science and Technology publishes refereed original articles on the fundamental and applied science of engineering composites. The focus of this journal is on polymeric matrix composites with reinforcements/fillers ranging from nano- to macro-scale. CSTE encourages manuscripts reporting unique, innovative contributions to the physics, chemistry, materials science and applied mechanics aspects of advanced composites. Besides traditional fiber reinforced composites, novel composites with significant potential for engineering applications are encouraged.
