Abstract: A repair kit for use in preparing a polymeric composite material and methods for preparing the polymer composite material are described. The repair kit includes a sealed container and a first removable divider arranged transversely across the sealed container. The divider is configured to engage the sealed container to form a first compartment and a second compartment. The first compartment and the second compartment are isolated from one another when the first removable divider is engaged with the sealed container. The first compartment contains a resin component and the second compartment contains a reactive component. The sealed container is configured such that removal of the first removable divider enables mixing of the resin component and the reactive component within the sealed container. The repair kit may also include a second removable divider to form a third compartment. The repair kit may also include a catalyst and a filler.
