Mechanical properties and process optimization of biodegradable PLA/jute multi-layer composites

Orthogonal test,variance analysis and analytic hierarchy process were used to analyze the construction and process parameters of biodegradable PLA/jute multilayer composites with a view to understanding the effect of process parameters on their mechanical properties.Six main factors such as proportion of PLA/jute fiber,layers of the composite,jute fiber direction,heating temperature,pressure and time,were studied.The results showed that heating temperature,jute fiber direction and proportion of PLA/jute fiber have notable effect on mechanical prperties.Layers and heating time have effect on some items,and pressure has little effect.The optimum process parameters are suggested.
