    Notes: Summary Microbially produced poly(3-hydroxybutyrate) (P(3HB)) and a copolymer were investigated by measuring tensile strength, Young's modulus and molar mass after different periods of thermal treatment at temperatures slightly above their melting temperatures in order to describe the changes of molecular and mechanical properties. The tensile strength turns out to be strongly influenced by time and temperature of heat treatment. After a heat treatment for 10 min at 190 °C the tensile strength drops to 30% of its initial value.

    Production and characterization of UHMWPE fibers/LDPE composites (1996)
    Springer
    Mechanics of composite materials 32 (1996), S. 497-503 
    Details

    Notes: Abstract The production of unidirectionally fiber-reinforced composites (tapes) consisting of high-strength/high-modulus UHMWPE fibers and LDPE matrix is described. Two production techniques are applied: impregnation by aqueous powder dispersion and dry powder impregnation. The produced composites exhibit excellent mechanical properties. Depending on the fiber volume content which can be obtained: tensile strength (in fiber direction) 460–1100 MPa, elastic modulus 11–22 GPa, and elongation at break 4.9–8.3%.
