摘要

针对竹塑复合材料（BPC）强度低和脆性大的缺点，研究采用热压成型工艺，在复合材料中分别引入四种竹编结构，即密编十字编（CW）、密编人字编（TW）、网孔十字编（MW）和单向帘编（UW），制备竹编增强的BPC。结果表明，与未增强的BPC相比，除TW-BPC外，其他3种竹编增强BPC样品的力学性能均显著提升，其中UW-BPC的抗拉强度和抗弯强度分别提高了108.3%和81.7%，抗冲击强度达到57.0 kJ/m

，约为未增强BPC的5倍。在低速冲击过程中，竹编的经纬结构展现出明显的抗冲击优势，10 J冲击能量作用下MW-BPC冲击载荷的峰值较未增强BPC提高79.6%。研究结果为竹材与BPC复合的创新应用提供了新思路。

Abstract

In view of the shortcomings of low strength and high brittleness of bamboo-plastic composite materials (BPC)

in this study

the hot-pressing molding process was adopted. Four bamboo weaving structures were introduced into the composite materials respectively

namely

oss weaving (CW)

twill weaving (TW)

mesh weaving (MW)

and unidirectional bamboo weaving (UW)

to manufacture bamboo-woven reinforced BPC. The results showed that

comparing with the unreinforced BPC

the mechanical properties of three other bamboo-woven reinforced BPC were significantly improved except TW-BPC. Among them

the tensile strength and flexural strength of UW-BPC increased by 108.3% and 81.7% respectively

and the impact strength reached 57.0 kJ/m

which was approximately five times that of the unreinforced BPC. During the low-speed impact testing

the warp-and-weft structure of bamboo weaving demonstrated significant impact resistance advantages. The peak impact load of MW-BPC at energy level of 10 J was 79.6% higher than that of unreinforced BPC. The research results inspired new ideas for the innovative application of the composite of bamboo and BPC.
