Affordable NDM (Non-Distribution Media) Vacuum Assisted Resin Transfer Molding (VARTM) Processing for Large Naval Structures

Sunrez Corporation has refined the LS-Process, an improved VARTM Vacuum Assisted Resin Transfer Molding process for the fabrication of large scale composite parts and ships. Sunrez has conceived and demonstrated the LS-Process which eliminates all of the under bag flow media usually associated with current VARTM processes. The currently used VARTM processes require an inordinate amount of under the bag resin distribution media and tubes and excess resin, which are thrown away after the part is fabricated creating higher material and labor costs. The LS-Process lowers costs with respect to labor and materials and has no under the bag resin distribution media. Sunrez has developed the LS VARTM Process to meets these requirements and is very low cost. In Phase I of this program, the LS VARTM Process was further developed and demonstration parts made which have shown the viability of this process to meet all of the Navy requirements for this program.
