With　the　view　of　improving　the　properties　of　PA6,　different　contents　of　thermal　liquid　crystalline　polyamide　were　blended　with　PA6　without　any　compatibilizer　to　fabricate　PA6/TLCP　composites　by　means　of　the　Haake　Rheometer.　Phase　behaviour,　tensile　properties　and　fracture　morphology　were　studied.　It　was　compatibilized　directly　and　without　phase　separation　when　the　addition　of　TLCP　less　than　10%.　Addition　of　5%　TLCP　in　PA6　increased　the　tensile　strength　by　5.2%,　Young＇s　modulus　by　38.3%,　and　elongation　at　break　by　280%　as　compared　with　pure　PA6.　Simultaneously,　the　morphology　was　typical　ductile　rupture.　As　the　addition　of　TLCP　in　PA6　beyond　15%,　it　was　difficult　for　particles　of　TLCP　to　be　dispersed　thoroughly　in　PA6　matrix,　which　induced　the　self-congregations　and　phase　separation　of　TLCP　along　with　the　typical　transition　from　tough　to　brittle　detected　by　SEM　resulted　in　the　dramatic　drop　in　mechanical　properties.　Addition　of　appropriate　content　of　TLCP　favored　improvement　in　toughness　of　PA6/TLCP　composites　without　the　expense　of　tensile　modulus.
