Notes:
PMR (polymerization of monomer reactants) -15 was formulated to use as a matrix resin for high performance carbon fiber-reinforced composite materials. Monomers for the PMR-15 were characterized using Fourier transform infrared spectroscopy. Molecular weight change during cure was investigated using gel permeation chromatography. Thermal analysis was carried out to investigate glass transition and thermal degradation. Cure behavior of a glass/PMR-15 prepreg was investigated using a dynamic mechanical analyzer. Flexural strength of a cured carbon/PMR-15 composite was affected by cure temperature and pressure. The morphology of the cured carbon/PMR-15 was affected by cure conditions as well as by the surface conditions of the carbon fibers. A scanning electron micrograph of the composite made of untreated carbon fibers showed a void-trapped morphology.
