[0018] DETAILED DESCRIPTION One: Combination figure 1 The present embodiment is an LCP composite film suitable for high frequency high speed, characterized in that the LCP composite film suitable for high frequency high speed includes the top to bottom, including TLCP layers (1), TLCP-plastic composite layer (2) and Grassroots (3);
[0019] The TLCP layer (1) contains TLCP and polytetrafluoroethylene, and the mass fraction of polytetrafluoroethylene is 15 to 30%, and the margin is TLCP;
[0020] The TLCP-plastic composite layer (2) contains TLCP fibers, PET and polytetrafluoroethylene, and the mass fraction of TLCP fibers is 10 to 20%, and the mass fraction of PET is 20 to 30%, and the margin is polytetrafluoro. Ethylene.
[0021] The tensile strength of the TLCP fibers exceeds 18CN / DTEX, which can greatly improve the tensile strength of the plastic article as the skeleton as the skeleton.
[0022] In this embodiment, PET is a polyethylene terephthalate which has good electrical...
Example Embodiment
[0023] DETAILED DESCRIPTION 2: Combination figure 1 The difference between the present embodiment and the specific embodiment is: the TLCP fiber is one or two layers in the TLCP-plastic composite layer (2); when the TLCP fiber is one layer, the TLCP-plastic composite layer (2) The mass fraction of TLCP fibers is 10 to 15%, and the TLCP fiber is provided in longitudinal direction; when the TLCP fiber is two layers, the mass fraction of TLCP fibers in the TLCP-plastic composite layer (2) is 15 to 20%, and the same The TLCP fibers are set together, and the adjacent two-layer TLCP fibers are intersected. Others are the same as those of the specific embodiments.
Example Embodiment
[0024] Detailed Embodiment 3: Combination figure 1 This embodiment differs from the specific embodiment of the other or two: the TLCP is a copolyester to hydroxybenzoic acid and 2-hydroxy-6-naphthoic acid. Others are the same as those of the specific embodiments.
