Archive image from page 212 of Development of a spherical acrylic. Development of a spherical acrylic plastic pressure hull for hydrospace application . developmentofsph00stac Year: 1970 Figu re F-2. Inspection of joints for presence of bubbles and undercuts at Swedlow Inc. capsule's critical pressure or serve as sources for incipient cracks under hydrostatic loading, the substantial decrease in number of bubbles in capsules 1, 2, and 3 resulted in joints with much better transparency and an improved all around appearance. Strength of Joints The quality of the joints was checked for each capsule by bonding together four blocks of 12 x 4 x acrylic plastic into two 12 x x joint specimens with the same batch of adhesive used on the capsule and in the same controlled environment where capsules were bonded. These joint specimens accompanied the capsule to the oven for annealing. After the capsule was completed and ready to be delivered to the customer, 12 tensile test coupons were cut from each joint specimen, with the joint in the center of each coupon. All of the test coupons were tested to destruc- tion, and the ultimate tensile strength of the joints was noted. 209
