Glossary
of materials engineering terms

 

Composite material failures.

Failure of Carbon Fibre Reinforced Polymer (CFRP) cycle frames

 

Select pictures below for larger images.

Certain frames are made by joining filament wound tubes to hand made corner 'lugs' in a taper - sleeve joint arrangement where the carbon fibres are not continuous across the lap region.

Failures in the wishbone area are away from such joints but are in the hand-laid lug where material properties are unlikely to be as high as those in the automated-manufactured tube sections.
