Carbon Fibre Composite Laminate Compression After Impact Test Fixture

Fixture and drop weight set that impacts composite laminates then compresses them to measure residual strength. Used by aerospace composite suppliers and airframe material labs.

Specification

A flat laminate is struck at a set energy using a drop tower, damaged area is recorded, and the panel is loaded in a guided anti-buckling fixture to failure. Compressive strength after impact is a core damage tolerance property for aircraft skins.

Features

• Anti-buckling support fixture for 100 x 150 mm panels
• Hardened steel hemispherical impactor 16 mm
• Adjustable impact energy by drop height and mass
• Fits any 100 kN universal testing machine
• Clamp pins and stiffeners to hold the plate edges
