Magnesium and Reinforced Plastic/Composites in The 1970s-Compatible or Competitive? 710647

The production of reinforced plastic/composites is projected at a 21% growth rate, primarily due to better public acceptance, low capital requirements, a wide range of fabricating methods, and technological breakthroughs. The properties obtained in RP/composites are dependent on types of resin, filler, and fiber used, with the type, orientation, length, and percentage of fiber being the key to its usefulness.Examined in detail are the methods used to fabricate fiber reinforced plastics and the effects of the various methods on the types of properties that can be obtained. In analyzing the competitive use of magnesium and reinforced plastics for lawnmower decks, price advantages were apparent in the use of RP, but product performance was unsatisfactory. The author concludes that complementary use of metals and RP will provide means whereby products can be created that will satisfy the market best.
