ASTM D7136/D7136M — Drop-Weight Impact Damage Resistance of Polymer Matrix Composites

← Back to all standards

ASTM D7136 is the test method for the damage resistance of continuous-fiber polymer matrix composites subjected to a drop-weight impact. To match this to your program, talk with our team.

What ASTM D7136 Covers

It drops a known mass and energy onto a composite plate and characterizes the resulting damage, such as delamination and dent depth, as the first step in a damage-tolerance evaluation.

Why It Matters

Impact damage in composites is often barely visible yet strength-reducing, so quantifying damage resistance is essential for aerospace and structural qualification.
