Prepreg process

Advantages §  Well defined resin content §  Excellent fiber wet out §  Clean handling §  Hygienic process

Limitations §  More expensive product §  Storage §  Impregnated waste



What is a B-stage

Chemical B – stage §  Chemical pre-reaction of the matrix system (adduct, pre-polymerization) §  Degree of conversion always below the gelation point of the system



What is a B-stage

Physical B – stage (1) Hot melt

§  “Melting” of a high viscous system mix (1 or x component) at elevated temperatures in order to decrease the viscosity during the period of the impregnation process (hot melt process)



What is a B-stage

Physical B – stage (2) Solvent containing systems

§  Formulation of high viscous system mix in solvent in order to enable fiber impregnation §  Evaporation of the solvent after impregnation process using a drying tower
