BSS 7260 (Boeing) — Composite Laminate Compression & CAI Testing

← Back to all standards

BSS 7260 is a Boeing company standard used in aerospace composite testing for compression and compression-after-impact (CAI) evaluation of fiber-reinforced laminates. To match this to your program, talk with our team.

What BSS 7260 Covers

It defines compressive testing of composite laminates, including residual compressive strength after an impact event (CAI), used in aerospace material allowables and damage-tolerance qualification.

How the Test Is Run

A laminate panel is first damaged by a controlled impact, then loaded in a supported compression fixture at a controlled rate with strain measurement to prevent buckling, and the residual compressive strength is determined.

Why It Matters

Residual strength after impact governs the damage tolerance of composite aerostructures; an anti-buckling compression fixture, an impact setup, and accurate strain measurement are essential.
