Overview

Randomized trial assesses thermo-mechanical degradation of GFRP composites, indicating temperature's critical role in structural design.

Key Points

  • The aim is to examine how elevated temperatures affect the thermal and mechanical properties of GFRP molded grating composites.
  • Evaluated three types of GFRP gratings—open-type, thin closed-skin, thick closed-skin.
  • Conducted three-point bending tests and various analyses including SEM, FTIR, TGA, DSC, and DMA.
  • Developed a second-order regression model to estimate flexural strength with high accuracy.
  • TCG-type specimens lost 43.9% strength at 320 °C, while OG-type showed significant degradation at 200 °C.
  • SEM and FTIR analyses detected substantial resin degradation and microcrack formation.
  • The glass transition temperature (Tg) was found to be approximately 115–120 °C.
