ASTM’s composite materials committee (D30) says that it is proposing a standard to help define the test methods and specimens that should be used for bolted joint related properties in composites.

Many composite structures are assembled with bolted (mechanically fastened) joints, and structural analysis of these attachments requires a linked set of design properties that are generated by D30 test methods. According to ASTM member Stephen Ward, the new standard will consolidate test specimen design content that is common across several existing committee standards into one guide.

“This new standard will provide guidance for test requestors to produce test data that can be used for typical bolted joint analyses of composite structures,” he said.

The proposed standard, called WK83618 could be used by aerospace engineers who need to design test methods for bolted joint configurations to produce to design data, ASTM said.
