Based on the modification of bismaleimide by allyl compound, a new type of high performance resin film which is suitable for resin film infusion (RFI) process is synthesized by employing poly(ethersulfone)(PES).The film is stable at room temperature and shows good properties of toughness and inadhesiveness. The main properties of the cured resin are 535 MPa for flexural strength, 16.7 MPa for impact strength, and 236 ℃ for HDT. It can be seen that flexural strength and impaet strength are much better than X4502 which is reported in Refs.[8], and HDT is a little less than that in Refs.[8].Comparitions were also reported for composite samples of same resin and fibre systems which were processed using the wet lay up with autoclave consolidation and RFI. The result shows that the matrix dominated property(i.e. ILLS) is higher for the RFI samples due to the reduced void content and improved wetting, and the fibre dominated properties are similar due to the similar volume fraction. The glass fibre cloth composite manufactured by RFI has execellent synthetical performance.
