General Properties

Soric SF is a special type of pressure stable polyester none-woven core material designed specifically for vacuum resin infusion. Unlike traditional core materials such as coremat, Soric core features pressure stable cells which will not compress under vacuum, maintaining its structure and thickness.

What is more unique about Soric is that it is designed to act as an internal flow media for the infusion, eliminating the need for infusion mesh during the resin infusion process. Its cells are separated by canals through which the resin can easily flow and which, once cured, create a rigid plastic honeycomb which adds considerably to the strength of the finished laminate.

Soric SF can be used to add thickness to any infused laminate including glass, carbon or Kevlar. It is compatible with all resin systems including polyester, vinylester and epoxy (although we always recommend epoxy for high performance composites).

Soric SF has a very low resin uptake and will provide at least a 30% weight saving over solid laminate. The cells have excellent compression and shear strength resulting in a very rigid core. By eliminating the need for infusion mesh and peel ply, the use of Soric SF can reduce layup time, save money on bagging materials and also avoid the waste of resin consumed by the by the peel ply and infusion mesh.

Typical Uses

2mm Soric SF is suitable for use in a huge range of closed mould and resin infusion processes including:

• Marine (hull, decks and superstructures of boats, yachts and larger models)
• Transportation / Motorsport (parts and panels for cars, trailers, trucks, RVs)
• Recreation (kayaks, canoes, surfboards, skimboards)
• Wind Energy (nacelle covers, spinners, enclosures)

• How to use Soric SF

  When using Soric SF inside a laminate there is no longer any need for an infusion mesh to facilitate resin flow through the reinforcement and therefore also no need for the peel-ply which usually separates the laminate from the mesh.

  Traditional Infusion Stack:

  Mould Surface | Reinforcement | Peel Ply | Infusion Mesh | Vacuum Bag

  Infusion Stack when using Soric SF as Core Material and Internal Flow Media:

  Mould Surface | Reinforcement | Soric SF | Reinforcement | Vacuum Bag

  Depending on the shape of the mould, resin is generally introduced into one edge of the laminate via infusion spiral. In some situations it may be helpful to position some infusion mesh along the edge of the project to facilitate resin distribution.

  As soon as the resin reaches the edge of the laminate it will infuse quickly through the canals in the Soric SF and through the rest of the laminate. The rest of the infusion is undertaken just as normal. Once cured the part can be demoulded and is ready for use.

  Depending on the type of vacuum bagging film you are using, it might also be necessary to use a release film between the laminate and the vacuum bag to prevent the bag from sticking to the laminate. If using materials from the Easy Composites range you will find that all of our vacuum bagging film is nylon based and as such will not stick to the laminate but for other non-nylon films you may find they will stick and so a release film should be used in such cases.
