- Rohacell provides a multitude of benefits for the processing composite parts, including the reduction of weight, low resin absorption and high temperature performance.
- It’s lightweight, high compression strength structure allows for high pressure and high temperature curing up to 8 bar and 220 Celsius, great for open and closed mould curing in autoclave, where other foams would simply crush.
- At SCC, we make composite components with Rohacell on a daily basis; from structurally integral components to lightweight brackets and fixtures. Using high performance core foams like Rohacell is a great way to get very high quality consolidation parts with high strength and low weight properties.
- We often use Rohacell in combination with a variety intensifiers and complex moulding structures to achieve even higher levels of pressures and consolidation that are clients are after, to further reduce weight and improve consistency.
South Coast Composites is a specialist manufacture of high performance composite components, working with clients in the Motorsport, Aerospace and Defence industries. Our clients are constantly designing to create higher efficiency products and driving out dormant material from their components to make margin gains that will win races, save fuel and reduce costs.
Rohacell comes in several grades with varying properties tailored for different industry applications, with altered foam cell coarseness, temperature stability, elongation performance and densities. However, we often work with industrial grade Rohacell due to its versatility across a number of applications, great compression strength and consistency.
As an AS9100 certified production facility, it’s important that our parts are made to the gram with consistent consolidation and quality every time. Rohacell is one of the most homogenous and consistent composite core materials on the market for high performance high value manufacturing. Which means that if we want to cure an open mould exposed IG51 (industrial grade 51kgm3 density) Rohacell component, we can rely on it maintaining its compression strength all the way up to the mark at 0.9MPa or 9 bar pressure and 130 Celsius.
In most cases, our clients specify their desired curing conditions and we work very closely with their technical department to get exactly what they want. However, on more free-flowing projects, with most medium temperature composite cures 120-125 Celsius and 8 bar peak curing conditions will suffice to get the best consolidation and surface finish possible.
On top of its performance characteristics Rohacell is also incredibly user friendly while handling for lamination or altering to customer specification. It’s possible to sand, machine, saw and slice the core material and due to its closed cell nature; it does not further expose the material to any additional resin absorption and leaves extremely clean cuts, due to its dimensional stability.
We have enjoyed using Rohacell for many years as Evonik has developed its range. We have recently begun testing some exciting new multi-part cores and to reach even higher consolidation levels with our customer and still Rohacell remains a core component in the ever developing nature of the composites industry.
