Abstract

PVA/LPRS composite was prepared in order to deep explore manufacturing technology and performance-controlling methods of rice straw based composite. The preparation course includes the following procedures: rice straw drying, rice straw cutting, mixing with PVA and hot-pressing. The effects of hot-pressing time and temperature on performances of composite were studied. Results showed that tensile strength first increased and then decreased with hot-pressing time. The tensile strength arrived at 3.67 MPa when hot-pressing time was 12 min, 51% higher than that hot-pressed for 8 min. Tensile elongation showed similar changing law as tensile strength. When hot-pressing time was 12 min, the tensile elongation was 22.5%. The hardness of composites was uneven and showed certain fluctuation. Hardness fluctuation range lay between 80 and 97. Tensile strength first increased and then decreased with the increase of hot-pressing temperature. When hot-pressing temperature was 150 , the tensile strength arrived at 3.41 MPa, 85% higher than that of composite prepared at 130 .
