An overview of endurance and ageing performance under various environmental conditions of hybrid polymer composites

Abstract

Fibre reinforced polymer (FRP) hybrid composites builds vertically due to the achievement of custom-made properties with lightweight. However, these materials have finding limitations in exceptional circumstances due to the unpredicted sustainability. Hence, it is necessary to create the database for the durable and sustainable low-density FRP hybrid composites with the support of significant experimental investigations. This review paper is mainly covers durability studies of various FRP hybrid composites under different environmental conditions. The thermal ageing, hydrothermal ageing, sea water, acid and alkali environment, ultraviolet radiation and stress cycle effects were extensively discussed with suitable scientific evidence in this work. Further, most of the FRP composites are rapidly degraded by underwater conditions at high temperatures. The failure mechanisms such as delamination, degradation of fibre and matrix, poor interfacial adhesion, matrix surface cracking, etc. are found to be dominant in the FRP composites under the hydrothermal and acid environment conditions also covered. The combination of natural/synthetic hybrid composites and addition of some nano fillers enhance the durability performance of hybrid composites significantly. However, ageing properties of hybrid polymer composites in different environment conditions need to study for various applications. The review process revealed that the life cycles of hybrid FRP composites mainly affected by stress cycle based on continuous usage.
