Abstract

In order to solve the question of sample damage encountered in the preparation of composite of carboxymethylcellulose (CC) and shortly cut rice straw (SCRS) by hot-pressing, waste paper (WP) was introduced as demoulding material. The tensile performance and hardness of composites at different CC mass contents were characterized. Results showed that WP had good demolding effect and integrate composite boards were easily obtained and sample damage was basically eliminated. Otherwise WP also showed certain strengthening role. The tensile strength increased by 88.8% at optimal conditions in comparison to the composites without WP. Tensile strength of the composite first increased and then decreased with increasing CC content. When CC content was 40%, the composite reached its highest strength of 2.87 MPa. Tensile elongation showed similar changing law as tensile strength. The tensile elongation arrived at maximum of 9.36% when CC content was 40%. Hardness of composites showed uneven property and maximum hardness waving range lay between 79 and 92.
