Experimental and Numerical Analyses of Optimized Composite Profiles for Aircraft Construction

  • Published:
Mechanics of Composite Materials Aims and scope

The paper provides a description of the design, finite-element analysis, and testing of two optimized composite profiles intended primarily for joining aircraft structures. Profiles with T and Y shapes were manufactured using the thermoforming technology by a one-shot process from a C/PPS (carbon fibers and a polyphenylene sulfide matrix fabric). Such profiles are usually loaded in the pull direction. A finite-element analysis was performed to provide that these profiles are able to withstand the prescribed ultimate load without causing their damage. Static and fatigue tests were conducted on both profiles to determine their strength and construction limits, and results similar to those from FE simulations were found, i.e., both the profiles could withstand the prescribed load without degradation.
