Abstract:
A rigid coupler (300) for use in electrically isolating an electrically conductive fluid conveyance system is described. The rigid coupler (300) includes a nonconductive liner (306) having a first end configured to couple to a first adjoining section of the fluid conveyance system, and a second end, opposite said first end, configured to couple to a second adjoining section of the fluid conveyance system. A reinforcing structure (308) circumscribes the nonconductive liner (306) and is coupled to a portion of the nonconductive liner (306) extending between the first and second ends of the nonconductive liner. The reinforcing structure (308) includes a multi-axial braided fiber material impregnated with a matrix material. A fiber overwrap (310) is hoop wound about at a least a portion of the reinforcing structure (308) between the first and second ends of the nonconductive liner (306).
Abstract:
A large scale composite structure is fabricated by forming a plurality of composite laminate modules (208d, 208e) and joining the modules together along their edges (210) using scarf joints.
Abstract:
The invention relates to a method of bonding two members together utilizing a stack of solid film adhesive and a layer of solid film adhesive, both disposed between the members. A pressure-applying device may be utilized to apply low pressure to force the members together. The pressure may force the stack to compress and expand in varying directions in order to substantially remove air-bubbles between the layer and one of the members. A heating device may be utilized to change the layer and the stack into liquid states in order to bond the members together with a void-free bond-line.
