| Abstract [eng] |
In this study, the carbon fibre reinforced methyl methacrylate resin composite (CF/MMA) toecaps for safety shoes were manufactured to change impact behaviour by incorporation of nanofillers. Different types of nanofillers such as nanotubes (inorganic halloysite, multiwalled carbon nanotubes) and unmodified and organically modified nanoclays (natural bentonite and montmorillonites) were dispersed inMMA composition. The low-velocity impact test with drop-weight machine was performed with respect to the nanofiller nature and carbon fibre stacking sequence. It was found that the most influence on the stiffness and impact damage of the CF/MMA nanocomposite toecaps show organic and inorganic nanotubes or unmodified nanoclay (bentonite). Effective amounts of these nanofillers improve the low velocity impact response in 16 %– 20 %. Although the influence of nanofillerson CF/MMA composites energy absorption capability at impact energy level of 90 J is negligible, however, theireffect on thesizeof the composite toecaps damage areais considerable. |
