At least in the interface region, layers of helical-filaments are displaced radially-outward and even inclined with respect to an axis of the cylinder such that they may follow a path with a radial component. A mid-strut fitting is provided which has a plurality of teeth on an inner circumferential surface. The plurality of teeth engage the helical-filaments in the interface region to provide a mechanical connection. Portions of surface and intermediate layers of the helical-filaments may be removed to expose ends of those filaments in the interface region before mounting the mid-strut fitting on the cylinder.

A plug-in constant velocity (CV) joint is assembled to a powertrain component using a power tool. The CV joint and powertrain component connect via a splined shaft coupling with a snap ring interlock. External bi-directional thrust features on the joint and component engage first and second arms of the power tool after the splined shaft coupling is partially inserted by hand. The arms are relatively movable along a longitudinal direction, and an actuator selectively applies a compression force to the bi-directional thrust features adapted to fully insert the splined shaft coupling and engage the snap ring interlock. The power tool monitors the compression force to detect the full insertion. The actuator automatically applies a predetermined expansion force to the bi-directional thrust features to verify engagement of the snap ring interlock, wherein the predetermined expansion force is less than a force sufficient to disengage the snap ring interlock. 1. Apparatus comprising:a plug-in constant velocity (CV) joint attached to a propshaft, wherein the CV joint has a first bi-directional thrust feature accessible from outside the CV joint;a rotating powertrain component configured to connect with the CV joint via a splined shaft coupling with a snap ring interlock that engages when the splined shaft coupling is fully inserted, wherein the powertrain component has a second bi-directional thrust feature accessible from outside the powertrain component; andpower tool having a first arm adapted to engage the first bi-directional thrust feature and a second arm adapted to engage the second bi-directional thrust feature after the splined shaft coupling is partially inserted, wherein the arms are relatively movable along a longitudinal direction, wherein the power tool includes an actuator selectively applying a compression force to the bi-directional thrust features adapted to fully insert the splined shaft coupling and engage the snap ring interlock by contracting the first ...
