Features & Benefits
- Materials Features
- Faced for Maximum Adhesion, Minimal Resin Use
Utilizing a composite surfacing material, the open cell structure in Infusion Grade PP Honeycomb is sealed, thereby allowing the flow of resin during processing to remain at the bond line with minimal penetration into the honeycomb core. The veil provides a continuous substrate for 100% adhesion to the panel skin material. The core does not incorporate any flow paths, so a careful selection of glass reinforcements that have a resin flow path capability is required. To help facilitate a uniform flow of resin through the sandwich structure, additional pass through holes are added to the honeycomb that pierce the surfacing material at one cell and allow resin flow from top to bottom of the sandwich. Spacing of these holes is typically 4" on center.
Infusion Grade PP Honeycomb features a composite surfacing material that is compatible with most laminating resins.
- Cost Effective
- Lightweight
- Easy to Use
- Vibration Dampening
The growing demand for lighter structures, together with environmental concerns, is propelling a migration to Lite RTM and Vacuum Infusion Processes as a more advantageous composite manufacturing methods. These closed molding processes eliminate VOC emissions, while reducing employee turnover and material costs, increasing cycle times and production output, and producing higher quality, better finished parts with closer tolerances.
With the same shear and compression properties of Plascore PP Honeycomb, Infusion Grade PP Honeycomb offers the performance benefits of toughness, lightweight, acoustical and vibration dampening
