A method is proposed for calculating the dimension distribution of nanocrystalline elements lamellar and fibrillar morphologies a polymer. Calorimetric data were used to calculate longitudinal size these in lamellae microfibrils ultrahigh molecular weight polyethylene. The calculation results are consistent with obtained by X-ray method.. Keywords: heat capacity, effect, lamella, microfibril,

Yarns of fiber assemblies such as ropes would abrade with each other during repeated stretching or bending. The yarn on abrasion failure is a main reason for the final assembly result relative movement to other. To explore influencing factors and mechanism, this work, taking Ultra High Molecular Weight Polyethylene Fiber (UHMWPE) research object, discussed influences abrading frequency tension ...
