    Filament wound rocket motor with in-wound metallic end ring [1]. The main problem with trap-lock joints is that the axial stress in the motorcase has to be transferred via shear in the joint to axial stress in the metal end-ring. A careful finite element (FE) analysis is therefore employed in order to verify the structural integrity of the joint.   Design of filament–wound domes based on continuum theory and non-geodesic roving trajectories Published on Sep 1, in Composites Part A-applied Science and Manufacturing DOI: /itesa Copy DOICited by:

    Carbon Fiber Reinforced Polymers (CFRPs) have been widely used in numerous applications where high specific stiffness and strength offer structural weight reduction and fuel efficiency.

    Attention is given to winding-machine and mandrel types, the analysis and design of filament-wound laminates, mechanical testing methods for laminated composites, composite joints, environmental effects, quality assurance methods, and representative . A friction article is a structural part (rather than just a facing) substantially entirely of carbon. The article is made up from sooner or later carbonized filaments which are bonded with an ultimately carbonized resin. For some operational requirements it is appropriate to attach a wearing surface which could be carbon of a different sort or which might not be by:
