Fracture mechanism of plant fibres

摘要: This paper, which describes work from an extensive study of various plant species, is aimed at presenting the best common physical description mechanism failure in tension cellulose-based fibres. A correlation coefficient r=0.69 was observed between mean tensile strengths and Young's moduli fibres extracted leaves, stems, other miscellaneous sources. observation attributed to increases modulus strength with decreasing microfibril angle increasing cellulose content. cylindrical cell model applied preconditioned 24 27° C 60% relative humidity. modification resulting expression used produce r=0.89 predicted measured strengths. However, importance content for presently illustrated species not reflected terms fracture strain, increased by showing why high works can be obtained different species.
