Abstract

The invention relates to a composite material which is used to manufacture automobile bottom deflectors; the composite material consists of UP resin P171-903B, flexible resin P193-01, fiber glass, low profile additive H814-902, styrene, BYK996, 501 anti-oxidant, heavy calcium carbonate, PBTB, MgO, conductive carbon black powder, Al(OH)3 and zinc stearate. The density of the prepared automobile bottom deflector is 1.8, which meets the light-weighted trend of the prior automobile; the deflector plays the roles of buffering and protecting the passenger carriage; meanwhile, the strength-to-weight ratio (the ratio of ultimate tensile strength to density) is higher than that of metal; the corrosion resistance in adverse environment is excellent, the bottom deflector is located at the car bottom; the size is precise, the stability is stable and good strength is kept in a wide temperature range; the inflaming retarding and aging resistance are excellent.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a composite material used for making a deflector at the bottom of an automobile. Background technique [0002] The deflector at the bottom of the car makes the bottom structure of the car smooth and closed, and the airflow can quickly pass through the bottom, reducing the lift force caused by turbulent flow, which is equivalent to increasing the grip of the tires, thereby improving the stability of the vehicle at high speed. At present, mid-to-high-end cars in foreign countries have basically installed bottom deflectors at the bottom, and the materials are mainly metal and fiber-reinforced plastics. The density of the metal material is high, which does not conform to the current trend of lightweight automobiles, and the strength of the metal is high, but the specific strength (ratio of ultimate tensile strength to density) is low, which is not conducive to the cushion...
