Foam core sandwich panel

fabric

It is new process,can produce high strength and density of homogeneous composite panel. Sew highdensity PU plate into the special 3 d fabric, through the RTM (vacuum moldig process). 3D FRP stiched foam sandwich panel is new process.New process can produce high strength and density of homogeneous composite panel. Sew highdensity PU plate into the special 3 d fabric, through the RTM (vacuum moldig process). Advantage ●Fully Fashioned. ●Panel face is very beautiful, ●High strength. ●One-time finishing, slove the problem of traditional sandwich panel foaming. Structure chart If it is molded in ordinary 3D cloth and then filled with PU foam, the foam will not be uniform, and the density will not be consistent. The strength of the panel will be very low. The largest width is 1500mm, you can choose the different foam, such as PU,PVC and so on. The PVC foam strength is higher than PU, the price is also higher. The PU foam thinnest is 5mm,the PVC foam thinnest is 3mm.The normal size is 1200x2400mm, for the normal panel choose the PU foam(density 40kg/m3) +two sides combo mat or woven roving, the total thickness is 20mm. Benefits of RTM The benefits of RTM Product surface will be fully defined during pressing - Large mould freedom and high fibre-volume(up to 60%) - Constant Reproducible - Continuous innovative industrialisation - Closed mould technique - What does it bring you? Low finishing costs and beautiful quality Ultimate mechanic properties Low dropout rate and suited for advanced applications Cost savings, higher tool capacity Barely any emissions and operator friendly
