The mechanical properties of insert-molded bimaterial composites

摘要

Bimaterial composite samples were constructed by injecting various polymers into a mold containing a fractionof a pre-molded specimen.The resulting series composites were tested in tension.Breaking stresses were independent of fractional length.Conversely,both elongation to break and apparent stiffness varied with fractional length.Although samples broke at or near the interface,adhesion was reasonably good,as indicated by transfer of material across interfaces.
