Spray binder for automated preforming: Spray process and preform properties
Polymer Composites, Volume 44, Issue 1, Page 432-443, January 2023., 2023 Spray binder for automated preforming Abstract A closer look was taken at a spray binder and the properties of the preforms made with said binder and non‐crimp carbon fiber textiles. First the spray process was analyzed, then T‐peel and three point flexural tests were carried out to compare the spray binder to other binder systems.
