PRELIMINARY RESEARCH ON ELECTRO BEAM CURING OF BISMALEIMIDE MATRIX/CARBON FIBER COMPOSITES

Bismaleimide matrix composite plates with carbon fiber as reinforcing material are cured using electro beam technology. After the resin being cured, its glass transition temperature tested by DMTA is 263.2 ℃. Results indicate that the tensile modulus is 128 GPa, the flexural modulus is 103.3 GPa and the tensile strength is 1 184 MPa.. The reasons of the data are also analyzed. It is suggested that the interface between the resin and the reinforcing material is very important and the interface coherence between the carbon fiber and bismaleimide resin needs to be improved.
