Void formation during RTM: An experimental and analytical study on the influence of bundle porosity on void formation during liquid composite molding in woven fabrics

Mechanical air entrapment, void compression and void dissolution are the main mechanisms behind void formation in liquid composite molding. Mechanical air entrapment is induced by the highly non-uniform geometry at the meso- and micro-scale and the heterogeneous properties of the reinforcing material. This results in differences in the velocity...
