A storage vessel can include a shell that is formed by fibers wound about an axis and infused with a resin matrix. The resin matrix can include metal nanoparticles coated with a polymer and distributed within a resin. The nanoparticles provide low coefficients of thermal expansion, and the polymer coatings enhance their bonding with the resin The shells of such storage vessels provide increased tensile strength and modulus at both room and cryogenic temperatures. Such improvements stem from the higher interfacial residual thermal stress at cryogenic temperature due to their low thermal expansion properties, which in turn promotes crack branching that increases the energy dissipation of the matrix.

Parts made by additive manufacturing are often structural in nature, rather than having functional properties conveyed by a polymer or other component. Printed parts having piezoelectric properties may be formed using a composite filament comprising a plurality of piezoelectric particles dispersed in a thermoplastic polymer. The composite filaments may be formed through melt blending and extrusion. The composite filament is compatible with fused filament fabrication and has a length and diameter compatible with fused filament fabrication, and the piezoelectric particles are substantially non-agglomerated and dispersed along the length of the composite filament. The piezoelectric particles may remain substantially non-agglomerated when dispersed in the thermoplastic polymer through melt blending. Additive manufacturing processes may comprise heating such a composite filament at or above a melting point or softening temperature thereof to form a softened composite material, and depositing the softened composite material layer by layer to form a printed part.
