Abstract

Detection of damage due to impact in an isotropic structure like metal, its alloys, etc. is an easy task but in the case of fibre reinforced polymer matrix composite structures, it becomes one of the critical factors which cannot be tolerated to use this structure extensively. Metals are usually ductile in nature as they can absorb more energy but in case of composite it is different; impact in composite reduces the structural strength. Most of the composite are brittle in nature. Composite can absorb energy in elastic deformation but not via plastic deformation. So it becomes important to consider the impact loading and influence of parameters to improve the damage resistance of composite structures in many applications like automobiles, aerospace, defense, etc. This paper presents the pivotal reviews of the previously published literature regarding the influence of parameters, damage mechanisms, enhancement of damage resistance of various composites. Firstly this paper briefly reviews the approach of analysis and the influence of stacking sequence on failure of the composite. Following this, the compendium review of other parameters for improvement of low velocity impact resistance specifically different constituents materials, geometrical factors, self-healing, bio-composites, off-centre loading and angle impact that influences the structural behaviour of different composites under the impact loading is briefly discussed. This review further discusses the different factors to be considered to enhance the impact damage resistance of fibre reinforced polymer matrix composites and concludes with future work discussion.

摘要

检测金属、其合金等各向同性结构中的冲击损伤是一项容易的任务，但在纤维增强聚合物基复合材料结构的情况下，它成为不能容忍广泛使用这种结构的关键因素之一. 金属通常具有延展性，因为它们可以吸收更多的能量，但在复合材料的情况下则不同；复合材料中的冲击会降低结构强度。大多数复合材料本质上是易碎的。复合材料可以在弹性变形中吸收能量，但不能通过塑性变形。因此，考虑冲击载荷和参数的影响以提高复合材料结构在汽车、航空航天、国防等许多应用中的抗损伤能力变得很重要。本文介绍了先前发表的关于参数影响的文献的关键综述，损伤机制，增强各种复合材料的抗损伤能力。本文首先简要回顾了分析方法和堆叠顺序对复合材料失效的影响。在此之后，对提高低速抗冲击性的其他参数的概要审查，特别是不同的成分材料、几何因素、自愈性、生物复合材料、简要讨论了影响不同复合材料在冲击载荷下结构行为的偏心载荷和角度冲击。本综述进一步讨论了提高纤维增强聚合物基复合材料的抗冲击损伤性能要考虑的不同因素，并以未来的工作讨论结束。
