TechSolutions 18 - Polymer Matrix Composite Manufacturing Induced Defects
In This Issue: 

Polymer matrix composites (PMCs) comprise more than 90% of the composite materials available. They are used extensively within industry and the DoD due to their high stiffness and strength, low density, long fatigue life, corrosion resistance, and crash worthiness.[ 1, 2] These materials can also be tailored to exhibit stealth characteristics, sensor capabilities, and high thermal or electrical conductivity.[3]

With many desirable properties, the potential applications for PMCs continue to increase. As a result, it is becoming ever more important to know, and have a basic understanding of, the underlying causes for polymer matrix composite (PMC) material failure, specifically those that result from the manufacturing process since it accounts for approximately 44% of the failures in [fiber-reinforced] PMCs.[4] These failures result from defects that are inherently introduced during the manufacturing process, either from the reactions that occur within the resin during material processing, or via mechanical, human, or environmental factors. This article surveys the common defects that result from the manufacture of PMCs.
