Abstract

The invention discloses a multi-station integrated environment glass fiber reinforced plastic bending creep test apparatus and method. The test apparatus comprises a lever loading device, a temperature control device and a data acquisition device; the lever loading device comprises a supporting column and a cross beam, the top of the supporting column is provided with the cross beam, the cross beam is provided with a vertical pressing rod, the bottom end of the pressing rod is provided with a pressing head for pressurizing a test piece, one end of the cross beam is provided with a balance weight, and the other end is provided with a loading weight; the temperature control device is used for adjusting the temperature of the sample; and the data acquisition device is used for acquiring creepparameters of the sample under a stress condition. The apparatus is simple in structure, the test load, temperature and medium environment are controllable., a specific service environment can be simulated to the greatest extent, large-batch tests can be carried out at the same time by adopting the multi-lever loading device, the time and economic costs can be effectively reduced, and an effective test way is provided for service performance attenuation research, service safety evaluation and service life prediction of resin-based composite materials such as glass fiber reinforced plastics.

Description

technical field [0001] The invention relates to the field of testing the mechanical properties of resin-based composite materials such as glass fiber reinforced plastics in the engineering application field, in particular to a multi-station integrated environment glass fiber reinforced plastic bending creep test device and a test method. Background technique [0002] Creep of resin-based composites such as FRP at room temperature is one of the main bottlenecks restricting their wider application. With the progress of FRP creep, its service performance will continue to weaken, eventually leading to crack aging, causing huge economic losses, and even serious environmental pollution problems. The traditional FRP bending creep testing machine has a complex structure and high cost. At the same time, the bending creep test cycle is long and cannot support large-scale testing simultaneously. In addition, the controllability of the test temperature and the environmental medium is n...
