FEATURE ARTICLE
Table 1. Comparison of AGP193/8552 fabric material properties from equivalent
demonstrator part lay-ups processed by SQRTM or by autoclave.
The plan consisted in developing a highly curved
skin integrated Z-spar for spring back compensation
definition and a 5.7 m long flat demonstrator panel
with integrated stiffeners.
The second phase of the project consisted in the
full size inboard flap part design, tool design and
manufacture, in the process parameter definition as
well as in the manufacturing of first parts qualification.
For this SQRTM development, thanks to the previous
R&D work and above risk mitigation steps, Sonaca
succeeded in producing directly first parts qualification
right.
Economical Potential of the SQRTM Process
Major recurring cost (RC) benefits shall come from
the process automation and the higher integration of
parts allowed by SQRTM. Although RC drawbacks of
the technology are related to the injection resin, some
right away cost savings could be obtained from:
-The near net-shape design which allows material
reduction of up to 5%,
-The disposal of bagging and associated ancillary
materials, cost of which is estimated at about 1% of
the "flying" materials,

and Quasi-Isotropic) processed by SQRTM or by autoclave.
