Abstract
In this paper, one kind of low profile SMC (Sheet Moulding Compound) has been introduced and used to produce the cylinder head cover. Two kinds of low profile additives (polystyrene and polyester resin) were blended and added to the resin to compensate for the cure shrinkage. The cure shrinkage of obtained low profile SMC was only 0.05%, which met the requirements for class A surfaces. Test sample were prepared by mould pressing. Properties testing of SMC were conducted according to the National standards. Results showed that all of the indexes of the low profile SMC met the specifications for the production of cylinder head cover. Some properties of cylinder head cover products have been investigated in detail. Experimental and performance testing results showed that this kind of cylinder head cover is suitable for the automotive application.
