Effect of thermal history on the micro-structure and tensile mechanical properties of hot pressing polyphenylene sulfide

Key Points

• Tensile mechanical properties significantly vary with different thermal histories.
• A study observing changes in micro-structure due to varying thermal conditions reports strength improvements of up to 30%.
• Analysis of the micro-structure under varying thermal conditions indicates distinct changes in fiber alignment and density.
• Implications may lead to enhanced material performance in industrial applications, with potential changes in production methods.
