Abstract:

Proposed in this paper is a concept of continuous self- reinforcement of polymer during moulding process-ing.In the investigation,first,the main techniques and equipment of self- reinforcement applied to the traditionalpolymer processing are introduced.Then,a technique and the equipment of continuous self- reinforcement based onvibration and elongation force fields are discussed in particular.Finally,the mechanism of polymer’ s continuousself- reinforcement under vibration and elongation force fields is analyzed,and the effects of vibration and elongationforce fields on the final properties of the product are revealed.The results show that the self- reinforcement of poly-mer products processed in vibration and elongation force fields is remarkable,which significantly improves the com-prehensive mechanical properties and microstructure of polymer products; and that the proposed continuous self-reinforcement technique is applicable to the practical production with diverse materials.
