Polyester fiber Soric SF

fabric

Soric SF is the general purpose grade, balancing resin flow and surface quality. Soric SF is therefore especially suitable for thinner laminates. Soric is a polyester nonwoven material with a compression resistant hexagonal (XF, SF, LRC) or random dot-printed (TF) cell structure. These pressure-resistant cells, which are separated by channels, contain synthetic micro-spheres. The cells do not absorb resin and therefore limit the total resin up-take. Since these cells are pressure resistant, they create thickness in the laminate even when pressure is applied by vacuum bag. The channels facilitate resin flow and form a pattern of cured resin with good mechanical properties and excellent bonding to the outer skins. Because of these unique properties and characteristics, Soric can be used as: Thin core (bulker), adding stiffness, while reducing weight Inter-laminar resin flow medium, eliminating the need for other (disposable) flow media Print blocker (liner), that meets the most demanding cosmetic and finish requirements.
