Effect of inter-laminar adhesive on yielding behavior of aluminum fiber-reinforced thermoplastic composite laminates
- Drexel Univ., Philadelphia, PA (United States). Dept. of Mechanical Engineering and Mechanics
An adhesive stress-release model is proposed to predict the thermal residual stress released due to the presence of adhesive layer in hybrid aluminum fiber/polymer laminate. The model is developed based on the thermal curing temperature and composite constituent properties, and is used to determine the laminate initial yielding and deformation behavior. The adhesive layer functions as a compliant layer to release the thermal residual stresses and to delay the yield occurrence, thus enhances the laminates deformation behavior. Compared with available experimental data for graphite/PPS and glass/PPS with 2024-T3 or 7075-T6 aluminum hybrid thermoplastic laminates, the proposed model presents a better prediction than some other commonly used models.
