Abstract
A composite structure includes a resin and a plurality of titanium dioxide fibers provided in the resin.
Claims4
A method of fabricating a structure having enhanced heat resistance, comprising:
- fabricating a plurality of randomly oriented titanium dioxide nanofibers into a paper mat using a binder, the titanium dioxide nanofibers having an average diameter of about 10 nanometers, the paper mat having a thickness no greater than 0.080 inches;
- after fabricating the paper mat, impregnating the paper mat with a resin to form an impregnated paper mat;
- forming a composite structure by heating the impregnated paper mat;
- and
- fabricating a structure using the composite structure, the structure having a thickness corresponding to said paper mat.

A method of fabricating an aircraft structure with enhanced heat resistance, comprising:
- doping a plurality of titanium dioxide nanofibers with anions to form a plurality of doped titanium dioxide nanofibers, the titanium dioxide nanofibers having an average diameter of about 10 nanometers;
- forming a paper mat comprising the plurality of doped titanium dioxide nanofibers and a binder, the paper mat having a thickness no greater than 0.080 inches, the plurality of doped titanium dioxide nanofibers randomly oriented in the paper mat;
- impregnating the paper mat with a resin selected from the group consisting of phenolic, benzoxazine and bis-phenol cyanate ester;
- forming a composite structure by thermoforming the impregnated paper mat;
- and
- fabricating the aircraft structure using the composite structure.
