Abstract

The traditional processes for the manufacture of high performance composite shell structures are (i) vacuum bagging (VB)/VB with autoclave cure VB(A), (ii) resin transfer molding (RTM), and (iii) compression molding. Over recent years, there have been a number of novel “infusion” processes introduced, which span the gap between VB(A) and RTM. The new processes are known by a confusing set of names or acronyms—each company uses a distinct name, yet often the processes are near identical. The infusion processes can be mapped onto four distinct generic processes:

  1. Resin infusion in the plane of the fabric (Type I),

  2. Resin infusion with a flow medium/transport or distribution mesh (Type II),

  3. Resin film infusion (Type III), and

  4. Semipreg techniques (Type IV).

This article describes the attributes of each of the four variants above and considers their relative advantages and issues.
