| Popis: | The aim was to modify products made of natural fibres in order to reduce the composite porosity, reduce flammability and improve the mechanical properties of epoxy laminates. In order to obtain desired properties chemical modification of roving and fabric with use of silanization and flame retardant treatment was conducted. For this purpose different types of silanes and flame retardant compounds were used. Flammability of prepared fibre - samples were tested by microcalorimeter (PCFC). In the effect of natural fibres modifications flammability of reinforcing fibres was reduced even by 400%. Investigations of porosity in natural fibre composites were carried out by X-ray tomography. Improvements of composites flammability was tested according to UL94. Mechanical tests with quasi-static loads according to DIN EN ISO 178 were carried out, to identify optimized modifications in fibre and matrix. By combining flame retardancy and improvement of fibre impregnation, one of the modifications is showing promisingly results. |
