An Experimental Investigation On The Bearing Failure Load Of Multi-Pin Joints In Composite Laminates

摘要

In this paper,an experimental study has been carried out to investigate the failure load and the failure mode of multi-pin joints of glass fibre reinforced composite laminates which have the stacking sequence of [0/+45/90/0]s subjected to a traction force.The laminates were manufactured by vacuum assisted resin infusion (VARI) and tested with a special fixture.The number of pins was set from 3 to 5,while there were two different arrang styles for each condition.The test results showed that the failure loads were directly affected by the number of pins and arrang styles.The ultimate failure loads increased with the number of pins.
