چکیده

Flax black spot was found in Ordos City 2022, mainly infecting leaves and the exocarps, causing turn yellow brownish with leaf tips before drying damage, exocarps became brown or a layer of mould which significantly affected yield quality. The Y3 K1 strains from infected were same pathogen flax identified as Alternaria alternata by morphological characteristics molecular identification. In pathogenicity test, A. caused severe on consistent those observed field. study for pathogenic identification ascertained new disease China lays foundation subsequent studies control.

Experimental Investigation of the Effect of Short Flax Fibers on the Permeability Behavior of a New Unidirectional Flax/Paper Composite

A new type of reinforcement for unidirectional natural fiber composites has been developed, where a paper layer is assembled with a layer of unidirectional flax yarns. The paper layer chemically and mechanically bonds to the loose yarns to maintain their alignment and enables better manipulability of the reinforcement during stacking in the mold. Unfortunately, the paper layer adversely affects...

hemp, and flax composites

This study characterizes the acoustical behavior of natural fiber composites. Regenerated cellulose fibers (Lyocell), hemp fibers, and flax fibers were embedded in an epoxy-matrix. These unidirectional composites were tested for their logarithmic damping decrement, the resonance frequency, the ultrasound velocity, the dynamic and static modulus of elasticity, and bending strength and density. G...
