| Abstract: | PPTA/nylon-1010 molecular composite is first prepared by coprecipitation methord which PPTA is used as reinforcement and nylon-1010 as matrix. The thermal behavior and mechanical property of PPTA/nylon-1010 molecular composite is investigatied. The results show that the presence of PPTA (A small amount) in PPTA/nylon-1010 molecular composite increases the melting point and crystallization temperature of nylon-1010, improves the tensile strength and tensile modulus of nylon-1010. It is interesting that only 0.3% (by weight) PPTA in PPTA/nylon-1010 molecular composite increases the tensile strength and modulus 30% and 25% respectivley. |
