Claim 8:
9. The self-monitoring method of strain for the carbon fiber reinforced plastic electrofusion fitting according to claim 8, the method comprising the following steps:
(1) at least one pair of electrodes are set on the surface of the electrofusion fitting body:
the surface where the electrodes are to be set is polished off with sandpaper, and a layer of silver glue is coated on the polished surface; electrodes with a thickness of 0.1˜0.5 mm are set on the surface with the silver glue to reduce contact resistance; or, electrode grooves are designed and manufactured on the surface of the electrofusion fitting during injection molding;
(2) connecting each pair of electrodes to a resistance measurement system, measuring and recording the resistance changes for strain monitoring when welding the electrofusion fitting or when the fitting is under loading.
