Abstract

Mechanical properties of polypropylene-cellulose cement hybrid composites have been studied for a fixed mass fraction of cellulose fibers (7%) but varying quantity of polypropylene fibers (0. 2% to 5%), and a fixed total mass fraction of the two fibers (4%). These experimental results are compared with the rule of mixtures predictions. It is found that there is a marginal ″negative″ hybrid effect in the Young's moduli. Hybrid effects in fracture toughness and strength are hard to detrmine and the difficulties are discussed. The source of fracture toughness comes mainly from the work absorbed in pulling out the cellulose fibers from the cement matrix. Contribution to toughness by the polypropylene fibers is insignificant because they are severely embrittled during fabrication of the composites. The major mechanism of fiber degradation is one of thermal oxidation. A solution to this problem is suggested and verified.
