    This report presents the results of bolt-pull-through tests conducted under room temperature13; and hot wet condition, on quasi isotropic and another optimised lay-up ('K' laminate with 100'13; countersunk holes in round disc-shaped specimens in as-received condition, as well as moisture13; I saturated condition: The specimens had central countersunk holes of nominal diameter - 5mm13; and 6mm Load %4 as applied through steel and titanium bolts with 10(ixB0; countersunk13; head,normai to the plane of the disc, while it was supported along the periphery by a speciaii.13; designed fixture13; Tests were carried out under stroke control using microprocessor based controller on Instron i13; i 1 341 load frames The load displacement graphs suggest higher load carrying capacity in13; bearing for titanium matenal compared to steel material under room temperature condition The13; maximum load to failure was higher for specimens with 6mm diameter and 4 4mm thickness13; under both types of testing environment
