8. Juriya na abrasion
Kevlar® yana da matukar juriya ga abrasion, wanda ke sa ya zama da wahala a yanke, kuma ɗaya daga cikin amfanin yau da kullun na Kevlar® kamar safar hannu ne na kariya ga wuraren da za a iya yanke hannu da gilashi ko kuma inda ake amfani da wukake masu kaifi. Carbon da gilashin fibers ba su da ƙarfi.

9. Chemical juriya
Aramid fiberssuna kula da acid mai ƙarfi, sansanonin ruwa da wasu ma'adanai (misali, sodium hypochlorite), wanda zai iya haifar da lalata fiber. Ba za a iya amfani da bleach chlorine na yau da kullun (misali Clorox®) da hydrogen peroxide tare da Kevlar® ba. Ana iya amfani da Bleach Oxygen (misali sodium perborate) ba tare da lalata zaruruwan aramid ba.

10. Body bonding Properties
Domin carbon fibers, Kevlar® da gilashi suyi aiki da kyau, dole ne a riƙe su a wuri a cikin matrix (yawanci resin epoxy). Saboda haka, ikon epoxy don haɗawa da zaruruwa daban-daban yana da mahimmanci.
Duk carbon da kumagilashin zaruruwana iya mannewa cikin sauƙi ga epoxy, amma haɗin fiber-epoxy na aramid ba shi da ƙarfi kamar yadda ake so, kuma wannan raguwar mannewa yana ba da damar shigar ruwa ya faru. A sakamakon haka, sauƙi wanda fibers aramid zai iya sha ruwa, haɗe tare da mannewar da ba a so zuwa epoxy, yana nufin cewa idan saman kevlar® composite ya lalace kuma ruwa zai iya shiga, to Kevlar® na iya sha ruwa tare da zaruruwa kuma ya raunana abin da aka haɗa.
