Abstract

This study aims to explore the hygrothermal aging behavior and damage mechanism of short glass fiber-reinforced Polyphenylene Sulfide (PPS/GF) composites under three complex environments: seawater, coolant, and alkali solution. The evolution of mechanical properties during hygrothermal aging was investigated through tensile, bending, and impact tests. Through Differential Scanning Calorimetry (DSC), Thermogravimetric Analysis (TGA), and Fourier Transform Infrared Spectroscopy (FTIR) revealed that the chemical structure of the resin did not change before and after hygrothermal aging. Analysis of the fiber-resin interface through Scanning Electron Microscopy (SEM) and microbond test showed that interfacial damage was the primary reason for the decrease in mechanical properties of PPS/GF composites. Furthermore, single-fiber tensile tests and FTIR study on fibers in an alkali solution environment revealed additional damage inflicted by the alkali solution on glass fibers.

短玻璃纤维增强聚苯硫醚复合材料在不同液体介质下的湿热老化行为

研究了短玻璃纤维增强聚苯硫醚（PPS/GF）复合材料在海水、冷却剂和碱液三种复杂环境下的湿热老化行为及损伤机理。通过拉伸、弯曲和冲击试验研究了湿热老化过程中力学性能的演变。通过差示扫描量热法（DSC）、热重分析（TGA）和傅里叶变换红外光谱（FTIR）分析表明，树脂在湿热老化前后的化学结构没有变化。通过扫描电镜（SEM）和微键测试对纤维-树脂界面进行分析，表明界面损伤是PPS/GF复合材料力学性能下降的主要原因。此外，单纤维拉伸试验和纤维在碱溶液环境下的FTIR研究表明，碱溶液对玻璃纤维造成了额外的损伤。

期刊介绍： Polymer Degradation and Stability deals with the degradation reactions and their control which are a major preoccupation of practitioners of the many and diverse aspects of modern polymer technology. Deteriorative reactions occur during processing, when polymers are subjected to heat, oxygen and mechanical stress, and during the useful life of the materials when oxygen and sunlight are the most important degradative agencies. In more specialised applications, degradation may be induced by high energy radiation, ozone, atmospheric pollutants, mechanical stress, biological action, hydrolysis and many other influences. The mechanisms of these reactions and stabilisation processes must be understood if the technology and application of polymers are to continue to advance. The reporting of investigations of this kind is therefore a major function of this journal. However there are also new developments in polymer technology in which degradation processes find positive applications. For example, photodegradable plastics are now available, the recycling of polymeric products will become increasingly important, degradation and combustion studies are involved in the definition of the fire hazards which are associated with polymeric materials and the microelectronics industry is vitally dependent upon polymer degradation in the manufacture of its circuitry. Polymer properties may also be improved by processes like curing and grafting, the chemistry of which can be closely related to that which causes physical deterioration in other circumstances.
