Effect Of The Bagging Configuration On The Properties Of Vacuum-Bagging-Only (Vbo) - Oven Cured In Complex-Shaped Composites

With the growing needs of the aerospace industry to produce larger composite components at reduced costs, Out-of-Autoclave (OOA) manufacturing technology is perhaps the answer for the problem. However, the development work of the OOA process using prepreg materials to achieve minimum void content...
