ASTM D6484 Testing Fixture

Open-Hole Compressive Strength of Polymer Matrix Composite Laminates

ASTM D6484 Testing Fixture
ASTM D6484 Testing Fixture

This test method is designed to produce notched compressive strength data for structural design allowables, material specifications, research and development, and quality assurance.

Factors that influence the notched compressive strength and shall therefore be reported include the following: material, methods of material fabrication, accuracy of lay-up, laminate stacking sequence and overall thickness, specimen geometry, (including hole diameter, diameter-to-thickness ratio, and width-to-diameter ratio), specimen preparation (especially of the hole), specimen conditioning, environment of testing, specimen alignment and gripping, loading procedure, speed of testing, time at temperature, void content, and volume percent reinforcement. Properties that may be derived from this test method include open-hole (notched) compressive strength (OHC)
