Overview

The ultimate goal for the fin preforms is to incorporate a phenolic leading edge with a low mass, high stiffness fin core material. Per precedent from USC RPL a phenolic edge is only necessary on the leading side of the fin.

Image shows the USC fin preform before their tip to tip layup. Note phenolic on one side.

 

The proposed design is as follows, a honeycomb core inside of a G10 structure with a phenolic leading edge. This implies two critical adhesive joins, attaching the honeycomb to the G10 and attaching the Phenolic to the G10.
