Carbon Fibre Engine blocks

5 August 2011 One Comment

Composite Castings in the US have developed a new lightweight, carbon fiber composite, four cylinder engine block. This engine block design was developed by Matti Holtzberg, president and founder of Composite Castings. The new block makes use of carbon fiber as the reinforcement for the base epoxy resin. The high performance compound is moulded into the finished engine block profile using Composite Castings proprietary moulding process that features low cost tooling and provides for faster cycle times compared to conventional moulding methods. The new engine blocks are apparently up to 50% lighter in weight than a comparable aluminium block.

The design is such that a composite block is cast to a net shape, which eliminates secondary machining, significantly reduces NVH due to the relationship between fiber and resin, does not corrode, and represents a huge reduction in its carbon footprint because there is no metal to melt. Also, in comparison to die casting, the tool cost is 50% less and the tool life is 5-10 times greater. The first block that CC is casting for the performance engine market is an aftermarket specialty engine, which can be an alternate to the popular Ford Duratec/Mazda MZR inline 4 unit. The carbon fiber composite block weighs 9.1kgs less than the stock alloy block. Looking further forward, an entire range of four- and eight- cylinder engine blocks is planned for motorsports as well as OEM automotive, truck and marine applications.

    I’m on way too tight a budget for something like this, but just out of curiosity, how much?
    (1993 range rover 3.9 V8 block, if it makes any difference)
    But, if I win big on the lottery…
