Degradation behavior of soybean straw reinforced PLA composites in different soil conditions
Source abstract
Abstract
Soybean straw reinforced Polylactic acid (PLA) composites were prepared by extrusion injection molding, the Box–Behnken experimental design method was used to obtain the optimal molding parameters, and the soil degradation behavior of composites was studied. Soil burial test was lasted 63 days, these composites were degraded in loam, clay and sand conditions, respectively. The weight loss rate, mechanical properties, fourier transform infrared spectroscopy, thermos-gravimetric and surface micromorphology were analyzed. After 63 days of soil burial test, the increased weight loss rate and the decreased mechanical properties indicated the weak interfacial adhesion, the change of infrared absorption peak illustrated that the degradation degree of fiber and matrix, and the appearance of voids and cracks showed the poor interfacial bonding quality. It is indicated that loam and clay conditions had a deeper influence on the degradation behavior of soybean straw/PLA composites than sand conditions.
