Spray binder for automated preforming: Spray process and preform properties

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. While the spray binder showed higher peel strength than most binders found in literature, the measured flexural strength was lower than the values found for powder.

Automated summary

This study examined a spray binder and preforms made with the binder and non-crimp carbon fiber textiles. The spray process was analyzed and compared to other binder systems through T-peel and three point flexural tests. While the spray binder demonstrated higher peel strength, its flexural strength was lower than that of powder binder systems.
