ASTM D3039 is the test method for the in-plane tensile properties of polymer matrix composite laminates. To match this to your program, talk with our team.
What ASTM D3039 Covers
It determines tensile strength, modulus, and Poisson ratio of continuous-fiber composites by pulling a straight-sided coupon, the primary composite tensile method.
How the Test Is Run
A tabbed, straight-sided coupon is gripped and pulled at a controlled rate with strain gauges or an extensometer, and the in-plane tensile properties are calculated from the load and strain.
Why It Matters
In-plane tensile data anchors composite design and qualification; careful tabbing, alignment, and strain measurement are essential to avoid grip failures.
