If a smooth finish is required on second skin turn over turn over honeycomb and first skin and repeat.

Resin impregnated honeycomb. Resin is a natural or synthetic compound which begins in a highly viscous state and hardens with treatment. Phenolics for fire smoke and toxicity performance in aircraft interiors. If smoothness is not necessary wet out glass then move the honeycomb.

Hexcels industrial honeycomb hexweb a10 core is a formable and flame resistant honeycomb made from resin coated aramid paper. First wet out the glass and lay the honeycomb into the resin and let it cure. Alan in little washington nc honeycomb is great stuff and very lightweight.

Honeycomb offers a core material that creates a light weight strong and extremely stable panel free from the common problems associated with standard panel composition. Resin impregnated honeycomb is used as a core in rigid strong assemblies like tabletops and is a lightweight alternative to traditional torsion box construction. Phenolic impregnated honeycomb is coated with a heat resistant phenolic resin creating a high strength to weight ratio that is corrosion resistant and thermally insulating.

Recently we added resin impregnated honeycomb to our product line. And cyanate esters for space structures and satellite applications. Phenolic impregnated has excellent creep and fatigue performance.

Bmi systems for high temperature performance. Phenolic resin impregnated honeycomb standard on fib r lite. It is an extremely lightweight high strength non metallic honeycomb manufactured with para aramid fiber paper dupont kevlar n636 or equivalent.

Hexweb aluminum honeycomb is also used for its excellent energy absorption characteristics for example in automotive crash test barriers. There are two problems with using it in your application 1. Typically resin is soluble in alcohol but not in water.

Gluing and getting a good bond with the skins can be difficult requires good clamps sandbags or vacuum press. Effect of natural environment on sandwich structure with ams 3722 paper honeycomb core this honeycomb core utilized for this project was 125 ib kraft paper with 35 per cent impregnation of phe nolic resin the core was expanded 20 to 1 during manufacture to give a cell size of approximately 0455 in. It is used heavily in aircraft construction.

Kevlar is the newest addition the honeycomb line.
