Polycore polypropylene (PP) honeycomb reportedly provides greater strength-to-weight ratio than traditional polyaramid or aluminum honeycombs. The cells of the PP honeycomb are essentially circular rather than hexagonal and are fused together rather than glued. The recyclable honeycomb can be thermoformed and cut to shape easily has energy-absorbing and sound- and vibration-damping properties, and is resistant to fungus, rot, chemicals and moisture.
Light weight, high compressive strength, anti-water, anti-humidity honeycomb can be used as a core structure in the transportation fields such as aerospace, aircraft, boat, yacht, van, marine, automotive, truck, rail and material handling, In this application. honeycomb can lighten bare weight, boost velocity ,save fuel, whilst reinforce strength and dampen vibration.
Now when apply into project,most popular and mature skin panel laminated on PP honeycomb is fiberglass with resin,to make out waterproof,light weight,stiffness strength FRP PP honeycomb sandwich panel then apply into van,boat,yatch,bus,marine and so on,as floor,ceiling,door,wall,partition panel and so on.
FRP skin panel thickness can be 1mm,1.5mm,2mm and more,most popular in practice is 1.5mm FRP skin. On FRP skin ,there can treat gel coat with different color or laminate plywood or other material to cater to different application purpose.
FRP PP honeycomb sandwich panel standard size is 1200*2400mm,skin thickness of FRP suggested 1.5mm,sandwich panel thickness from 10mm to above.FRP PP honeycomb sandwich panel in our system is FRPan.
Polycore PP honeycomb most popular model PP8T40F which mean PP honeycomb corecell is 8mm, on both sides of honeycomb there are polyester tissue 45g/square meter, between core and tissue there are one layer of PP film, which can prevent more resin leak into corecell when clients laminate surface panel on the PP honeycomb sheet. At same time PP film enforce the bonding of PP honeycomb core and Polyester tissue so peeling strength of PP honeycomb sheet improved much more that provide guarantee for long life of finished products to avoid polyester tissue apart from honeycomb core after long time application in project.at same time since there is no more resin leakage into core so finished products is kept very light then save energy,improve speed and reduce resin consumption in lamination.
Now we can supply 1200*2400mm,1220*2440mm,1150*2300mm (for container size), max width within 1220mm,max length within 2600mm. Thickness from 4mm to 200mm.Most popular in practice thickness from 6mm to 60mm.Such as 6mm,10mm,12mm,15mm,18mm,20mm,25mm,30mm,35mm,40mm.
