Aerosol Valve Stem Pulling-off Strength Testing

Aerosol valve stem pulling-off strength testing is very important to aerosol valve quality. Aerosol valve has inner stem and outer stem. Labthink PARAM XLW(PC)Auto Tensile Tester can test the aerosol valve stem pulling-off force. Put the stem in between the upper and lower clamps, and pre-set the tensile speed at 50mm/min. Then, choose tensile resistance testing and start. The strength for aerosol valve to leave the valve body is the pulling-off strength. According to requirements, the final testing results should be statistical values of the maximum value of more than 3 specimens. The inner stem should be no less than 49N, and the outer stem should be no less than 40N.

I had a test today can some one tell me the answer?

I just want to know if i was right the question was
Q1. Even though there are an increasing amount of carbon fibre compsite materials being used in construction of aircraft for the civil market, the majority are still made from aluminium alloys. Cabin wings panels are fixed to the structural members using thousands of pop rivets and adhesives which is time consuming business. Why is this old fashoined technique still used.
I wrote this question on paper as thought it was quite hard

I imagine it's to ensure that the body stays in one piece. It would be incredibly dangerous if a section was displaced.

Hybrid Adhesive Joints $179 This volume treats the material science and mechanical issues of hybrid adhesive bonds which are a combination of adhesive bonding rather than mechanical fasteners. The idea of hybrid joints is to gather the advantages of the different techniques leaving out their problems. Some of the advantages of these joints are a higher static and fatigue strength and a higher stiffness with respect to simple joints, a two-stage cracking process before the final failure and improved durability. The book treats all important kinds of joints which are in use today: weld - adhesive, rivet - adhesive, clinch - adhesive, bolt - adhesive, and adhesive - adhesive. A section dedicated to threadlocking and interference-fit adhesive joints is also included. All sections are treated from a scientific point of view with modeling issues supported by simple coupons testing and a technological point of view where the idea is to present more applied results with practical cases.
