This invention provides a nested, zoned, controlled vacuum insert for film-coated injection molds. A first cavity is provided on the core-side main insert, and an external vacuum insert is disposed within the first cavity. A first vacuum gap, communicating with the cavity, is formed between the outer wall of the external vacuum insert and the inner wall of the first cavity. A first air passage is provided on the external vacuum insert, communicating with the first vacuum gap to form an outer air passage. A second cavity is provided on the external vacuum insert, and an internal vacuum insert is disposed within the second cavity. A second vacuum gap, communicating with the cavity, is formed between the outer wall of the internal vacuum insert and the inner wall of the second cavity. A second air passage is provided on the internal vacuum insert, communicating with the second vacuum gap to form an inner air passage. A main air passage, communicating with an external vacuum device, is provided on the insert body. The first and second air passages are connected to the main air passage.

A high-elasticity carbon fiber yarn and three-dimensional tape are disclosed, comprising a main elastic core, elastic binding threads, and chopped carbon fiber filaments. Several chopped carbon fiber filaments are crimped end-to-end onto the outer surface of the main elastic core, and each chopped carbon fiber filament is fixed to the main elastic core by the elastic binding threads. The chopped carbon fiber filaments are impregnated with silicone resin. The carbon fiber tape woven by this invention uses high-elasticity carbon fiber yarn, which has strong elasticity, enabling the tape to fully adhere to the core during winding. The composite product after resin impregnation and curing is wrinkle-free. The elastic warp yarn made of chopped carbon fiber filaments, after resin impregnation and curing, can also provide significant tensile strength, just like filament yarns, to tightly cross-link the weft yarns.
