[18, 19] also performed an experimental and numerical investigation of the effects of bolt torque, clearance, and countersunk height ratio on damage progression and strength of countersunk composite joints
. It indicated that the introduction of the countersunk hole roughly halved the bearing stress and caused delamination for some configurations.
Specimen CBJ4 was used as the benchmark for comparison with the other composite joint
specimens, which was a composite joint
with an RC slab of 100 mm in thickness, web anchorage plates of the stiffening type, and concrete fully filled into the steel tubes.

Note that 30 kN is about 80% of the failure load of the single-lap double-bolt composite joint
(2) Based on these results, the main results about the sensitivity analysis of parameters on the 3D braided composite joint
is as follows: the main truss diameter thickness ratio [gamma] > fiber braiding angle [alpha] > load parameters n > competent diameter d > main and branch diameter ratio [beta] > fiber volume content [V.sub.f] > branch and main thickness ratio r.

of New South Wales, Australia) presents a complete set of composite joint
design requirements, design methods, and analysis equations and techniques to aid engineers, technology managers, and technicians in developing structurally efficient and cost-effective composite structural joints.
Taikoo Spirit Aerosystems, airbus Taikoo Spirit Aerosystems, a composite joint
venture between HAECO and Spirit AeroSystems, took delivery of two GE90 thrust reversers to be overhauled.
The figure reveals that joint strength has increased from 6.1 to 21.5 MPa after atmospheric pressure plasma treatment resulting in more than three times improvement in the adhesion properties of the composite joint
after the plasma treatment.
An experimental program for investigating the composite joint
was first developed.
