The Simplifiers Our pre-impregnated materials made from carbon, glass, and aramid fibers SIGRAPREG® Composites – Fibers & Materials

<  < 3 SIGRAPREG® snap-cure Simple. Fast. Cost-efficient. SIGRAPREG from SGL Carbon is the brand name for state-of-the-art pre-impregnated reinforcing materials that can be combined with different resin systems, such as our fast-curing snap-cure epoxy resin system we developed in-house. Curing times of between 1.5 and 3 minutes and the possibility of using simple isothermal processes permit very short cycles in automated large-volume production of composite components. In this way, long production runs – like the ones required in the automotive industry – can be produced very simply,...

Simplifying component production by pre-impregnation Our pre-impregnated materials are ideally suitable for the production of stiff, strong, ultra-lightweight fiber composites as are often required for lightweight parts, high-tech applications, and components subject to extreme stress. From the automotive industry and industrial applications to aerospace and the energy sector, our prepregs have become established worldwide as the preferred material for challenging applications. In addition to their outstanding mechanical properties, our prepregs make an important contribution to efficient...

Simple, flexible: our material toolboxes For fiber-reinforced thermosets used in automotive and aerospace applications, we have developed material toolboxes consisting of pre-impregnated semi-finished products. These toolboxes contain a wide variety of reinforcing materials all based on the same resin system, which is tailored to the specific application. In this way, time and money that would otherwise be spent on qualification processes, tests, and process optimization is reduced. In addition, the various materials have guaranteed compatibility with each other and so can be flexibly...

A complete portfolio: prepregs based on woven fabrics, non-crimp textiles, and non-wovens, adhesive films and TowPregs We supply the whole range of textile reinforcing materials produced from carbon, glass, and aramid fibers and impregnated with various resin systems – from prepregs based on woven fabrics, non-crimp textiles, and non-woven fabrics to adhesive films and TowPregs. Our pre-impregnated materials have outstanding, reproducible properties and can be tailored perfectly to individual requirements. We use state-of-the-art resin systems that we formulate ourselves in-house. In...

SIGRAPREG prepregs are the result of our consistently customer-focused product development. They unite maximum performance with minimum weight and can be optimally adapted to the requirements of different end uses. We combine high-quality resin systems that we formulate ourselves in-house with state-of-the-art reinforcing materials. Our range comprises a wide variety of resin systems with different glass transition temperatures, curing temperatures and times, viscosity, tack, and storage stability. 1 Brand name 2 Material 3 Type 4 Fiber areal weight 5 Weave, fixation fiber orientation 6...

The Simplifiers | Resin systems and prepregs Our pre-impregnated semi-finished products are based on unidirectional, multiaxial, woven, and non-woven fabric structures. We produce unidirectional and multiaxial prepregs with different areal weights and a wide variety of reinforcing fibers. They can be produced with our own fabric structures as well as by direct processing of the reinforcing fibers without additional fixation. The woven fabrics are made in our own weaving facility from 1k, 3k, 6k, 12k or 24k carbon fiber rovings. In hybrid woven fabrics, we also process glass and aramid...

SIGRAPREG TowPregs are pre-impregnated fiber bundles made from carbon and glass fiber heavy tows. Besides the fiber type and resin system, it is also possible to individually adjust resin content and TowPreg width and produce to very high consistency. In this way, together with our customers, we can develop the optimum material, even for special applications. Our TowPregs help achieve better results in challenging processes. They not only impart excellent mechanical properties to components, they also have outstanding processing properties because of their constant width and optimized tack....

The Simplifiers | TowPregs and adhesive films Our SIGRAPREG adhesive films are thin resin films, e.g. made from epoxy or phenolic resin systems. They ensure good adhesion between our prepregs and various core materials such as honeycombs, metals, and foams. The adhesive film formulations are specially matched to our prepreg resin systems to ensure optimum compatibility. In this way, sandwich and hybrid materials for a wide variety of applications, for example in the aerospace and automotive sectors, can be produced even more efficiently. t SIGRAPREG adhesive film for bonding prepregs to...
