Abstract

The present disclosure relates to a composition for a radar transmissive cover for a vehicle, which may enhance dielectric properties while excellently maintaining mechanical properties. The composition, as the composition forming the radar transmissive cover for the vehicle through which a radar beam radiated from a radar is transmitted, has a main material in which 70 to 90 wt % of Polybutylene Terephthalate (PBT) and 10 to 30 wt % of Polycarbonate (PC) are mixed and an additive containing at least reinforcing filler mixed.

Description

technical field [0001] The present disclosure relates to a composition of a radome for a vehicle, and more particularly, to a composition of a radome for a vehicle that can enhance dielectric properties while excellently maintaining mechanical physical properties. Background technique [0002] Recently, as the focus on self-driving vehicles has increased, the demand for vehicle radar technology that enables vehicles to drive autonomously has also increased. [0003] A representative example of applying vehicle radar technology is an intelligent cruise control system. [0004] The smart cruise system is a system that senses the movement of the vehicle in front through the radar installed at the front of the vehicle and controls the engine and brakes according to the sensing results to accelerate and decelerate the vehicle, thereby avoiding the vehicle in front and changing lanes, or in the absence of A system that enables the vehicle to travel at a constant speed after re-ac...
