Kompoziti s plastomernom matricom ojačanom vlaknima

Polymer based composites with thermoplastic matrix is a growing market, still there are some limits due to the problem of high viscosity and fibres impregnation. In this work, an overview of polymer based composites is given with an emphasis on composites with thermoplastic matrix. Four sheets of composites of carbon fibres reinforced ethylene and methacrylic acid copolymer were prepared with different processing parameters. The sheets are analysed by means of optical microscopy. Flexural elastic modulus and apparent interlaminar shear strength were tested. The results show a great influence of processing parameters on successful impregnation. With only one layer of unidirectionally oriented fibres and a mass fraction of approximately 2.5 %, flexural modulus increased for 39 %, with a potential of over 80 % compared to the unreinforced thermoplastic polymer.
