Abstract
In order to satisfy the requirement of efficiency and reliability for prepreg change bonding during composite automatic placement and winding process, based on rheology theory and Gutowski analytical method of layup, hot-press bonding model was established firstly. Then, the control equation of resin fluid under parallel plate squeezing was established by power law model. Finally, the relationship between bonding strength and bonding pressure, resin viscosity, bonding temperature, bonding time (or bonding velocity) as well as bonding length in static bonding state and dynamic bonding state were analyzed, and static and dynamic hot-press bonding mechanisms were designed. The results show that the bonding strength of prepreg increases with the increase of bonding pressure, bonding temperature, bonding time and bonding length. The conclusions obtained can help to design the bonding mechanism which satisfies the requirements for fast, stable and reliable etc., and lay the theoretical and designing foundations for the development of prepreg rapid hot-press bonding system.
