主 题：maize stalk biomimetic elytra starch laminated board flexural property
摘 要：In this study,maize stalk tegument separated from the maize pith was crushed to obtain the *** cross-linking maize starch adhesives considering four main factors(water content,gelatinization temperature,NaOH as gelatinization agent and Na2B4O7·10H2O as cross-linking agent)with three levels were prepared based on an orthogonal test scheme L9(34)in order to increase the water-resisting property and the bonding strength of the common maize starch *** bonding properties of maize starch adhesives were characterized using shearing strength under compression *** models of fiber reinforced composites were established according to the microstructure analysis of the four species of insects’elytra including Protaetia orentalis,Copris ochus Motschulsky,Anoplophora chinensis and Cytister bengalensis Aube,which will provide the biomimetic models for the biomimetic laminated *** maize stalk fiber biomimetic laminated boards were prepared based on the structural models of the elytra *** flexural strength and flexural elastic modulus of the biomimetic boards were *** results showed that the flexural strengths of the single layer jute fiber,-reinforced maize stalk fiber boards and the dual layer jute fiber reinforced maize stalk fiber boards are higher than those of the common maize stalk fiber boards and the other three groups of jute fiber hybrid reinforced stalk fiber boards because of the biomimetic laminated design.
