Prepregs

composites
Prepregs are the combination of a fibre based substrate with a resin system in a form that is semi solid. As the manufacture of the prepreg is a controlled process very accurate and uniform fibre to weight ratios are achieved. This in turn is vital in enhancing or delivering the desired properties of the final composite component. Prepregs are advantageous in that the fibre and resin are premixed which leads to a very clean and controlled laminating process.

GMS Composites offer a range of prepreg products for different applications and our lean and flexible manufacturing facility means that we are ideally positioned to offer both long run and short run tailored solutions.

GMS EP-280 PREPREG
Product
GMS Composites EP-280 is a formulated epoxy resin matrix prepreg with long shelf life.

GMS EP-620 PREPREG
Product
GMS Composites EP-620 ballistic prepreg is a toughened epoxy resin matrix system with long shelf life, designed for ballistic and defence applications. The product has a versatile curing cycle from as low as 80oC or as high as 150oC, thus enabling the product to be used to produce a wide range of ballistic items, from large structures to numerous small components. EP-620 is available in a range of substrates such as aramid, s-glass, polyethylene, carbon or e-glass. This toughened system has outstanding fracture properties and impact resistance. The prepreg has good flow and the tack of EP-620 can be varied.

Applications
When combined with fibres such as aramid, s-glass, polyethylene or carbon, EP-620 can be used to produce items such as hard armour, helmets and other ballistic and protective components. These products have applications in defence, military, personal protection, vehicle protection and infrastructure shielding. It can also be used in the construction of sandwich structures. The versatility of EP-620 means that large complex structure as well as small basic components can be produced.


GMS SI-220 PREPREG
Product
GMS Composites SI-220 prepreg is a high temperature resistant silicone based prepreg. This low tack dry prepreg can be used to manufacture sheets, tubes or other components. Once cured, components made form SI-220 can perform at temperatures up to 220oC. The non-toxic inorganic nature of the silicone resin allows this products to be used in a range of high temperature applications. When subject to temperatures above 250oC the product forms a more crystalline structure but it will not burn or emit toxic smoke.

Applications
GMS SI-220 prepreg can be used for high temperature applications. Components made from this prepreg can be used as insulation in induction heating or microwave applications. Industries that require a composite product that will not burn or degrade when subject to fire can also utilise this product.
