Abstract
Prepregs, which are resin-impregnated and expensive composites, are mainly limited to high-end applications within the aeronautical, defence, automotive, and energy sectors. Prepreg technology is mainly protected by under trade secrets resulting in limited studies on recent advancements. A Scopus search revealed 861 articles and 16 reviews for the keywords ‘epoxy’ and ‘prepreg’. However, this was narrowed down to 123 articles and 4 reviews using keywords ‘formula development’ and ‘B-stage’. In this review, the control strategies of B-staging, resin tack, and viscosity and their measuring techniques are discussed. Based on resin impregnation techniques and B-stage control, two approaches are proposed to develop prepreg resin formulations: conventional resin impregnation and viscosity-controlled resin impregnation. The approaches would be extremely useful especially for advancing beyond the existing prepreg applications and developing smart materials and functional composites through advanced resin modification strategies.
