"LARC-I-TPI" denotes improved version of LARC-TPI class of thermoplastic polyimides: high-performance polymers developed for manufacture of strong, lightweight aircraft structures. Melt-flow and adhesive properties of new polymers make them attractive for use as matrix resins for composites, molding ...
A novel form of LARC-TPI has been developed which does not exhibit a crystalline melt as was encountered in earlier fonns of this material. Being amorphous allows the powder to be consolidated at temperatures near its glass transition temperature of 260°C (500°F). Adhesively bonded titanium ...
If the release of stored strain energy is stress controlled, then at sufficiently high levels of stress to cause a permanent structural arrangement of the polymer chains, polycarbonate and LaRC-TPI behave as nonlinear viscoelastic materials. If the current stress is less than the maximum stress the...

Biaxial films of polyimide LARC—TPI and LARC—TPI/liquid crystal polymer Xydar®were extruded directly from the melt for the first time via an innovative new extrusion technique. Three types of films, neat LARC—TPI, LARC—TPI/lO wt percent and 30 wt percent blends were processed as a ...
LARC-TPI can be processed as a thermoplastic polyimide to form high strength bonds. However, this is generally accomplished by processing at relatively high bonding pressures, i.e. 2.07 MPa (300 psi). This paper covers the investigation of the effects of two bisimide additives to LARC-TPI ...
