ASTM D6742 is the practice for filled-hole tension and compression testing of polymer matrix composite laminates. To match this to your program, talk with our team.
What ASTM D6742 Covers
It defines how to run tension and compression tests on composite coupons with a fastener or pin filling the hole, representing bolted-joint conditions.
How the Test Is Run
A coupon with a filled hole is loaded in tension or compression in the appropriate fixture, and the filled-hole strength is determined from the failure load and gross area.
Why It Matters
Filled-hole strength represents real bolted joints better than an open hole; correct fastener fit and fixturing are important.
