SMC、BMC用于制造汽车的沿革与灿烂前景

本文介绍了：1．SMC、BMC的优缺点及其汽车制品的种类，几国SMC市场简况；2．汽车制造业采用SMC、BMC的沿革及近况；3．轻质、高强SMC、BMC汽车零件的研制与实例；4．SMC制品的基准产量^[注]；5．SMC面临的挑战（[注]：SMC制品客观上存在着一个随时间推移而递增的基准产量，低于此基准其本低于同类钢零件，高于此基准时则高于钢零件；1986年和1996年的基准分别为7和15万件／年；目前北美半数以上的SMC公司的产量都低于10万件／年，由此可见SMC的潜力很大）。

An Evolution and Bright Prospects of SMC/BMC Used for Making Auto Parts

This article has described:1.definition,advantages and disadvantages of SMC/BMC,types of SMC/BMC auto parts,brief introduction of markets of SMC of some countries;2.the evolution and recent developments of SMC/BMC used for making auto parts;3.the developments and some living examples of light weight,high strength SMC/BMC auto parts;4.a crossover point of SMC output and 5.some challenges of SMC(Note:Objective reality of SMC products is there is a crossover point,which is increased as time is going on,of SMC output;when the output of that is lower(or higher) than such crossover point,the production cost of that is lower(or higher)than the cost of the same type steel product.The crossover point of 1986 is 70 000 piece/year,and 1996 is 150 000 piece/year.Now,the outputs of more than a half of SMC companies in North America are lower than 100 000 piece/year each other,so,there are great potentialities of SMC).
