JSF08 high precision short fiber morphology and mechanical property tester

Introduction

Conventional fiber strength measurement has a wide range of experimental instruments, however, for materials such as bamboo fiber, fineness, strength, short length, fragile and easily broken, such materials in the experiment of specimen preparation is big problem, also need corresponding to this special material experimental tensile device. The tension apparatus is developed under this background by special precision chucks are carried out on the specimen clamping, ensure the fiber extension in tensile process does not slip. The instrument optical measurement system through the surface morphology of the fibers were observed and filmed the fiber tensile process, and the bamboo fiber sample accurate positioning in the chuck through the vertical optical system.
