Particle Size and Proportion Influence to Impact Properties of Particulate Polymer Composite
نویسنده
چکیده
Current research concentrates on the impact properties of a particle reinforced polymer matrix composite material. The composite material consists of unsaturated polyester resin that is reinforced with aluminium hydroxide. Aluminium hydroxide acts as the hard phase and polyester as the binding agent. The aim of the work was to understand how the particle size and the filler material’s mass fraction influence the impact resistance of the composite. Additionally was studied the effect of postcuring to the impact toughness of the matrix. The testing was done according to the ISO 179 Determination of Charpy impact properties. Smaller particle size increased the impact strength. Filler caused embrittlement of the matrix as did also post-curing.
