The abundant fast-growing Chinese fir was confined to nonstructural use for its poor mechanical and fire performance, and classified as low-quality building materials. Herein, Chinese fir was impregnated with boric-phenol -formaldehyde (BPF) resin, and then processed using high-frequency heating according to practical processing and application. The properties of BPF-specimen were tested, and the results showed, compared with the common plate hot pressing, high-frequency heating was an efficient technology for its high heating rate according to commercial process. Compared with the control, the mechanical properties and fire performance of BPF-specimen were improved obviously, and the more the resin retain, the better the properties of the modified specimen.
