Analysis of porosity and mechanical behavior of composite T-joints produced by random vibration-assisted vacuum processing

Voids are viewed as one of the most significant manufacture defects found within the composite T-joints and have been demonstrated to reduce their mechanical performance. In this work, the random vibration was introduced into the curing process with vacuum bag pressure to minimize the void content and improve the mechanical behavior of the composite T-joints. The range of accelerations was covered from 5 to 15 g, for different period of random...
