Materials and Methods Raw materials: HDPE was obtained from ADV System Technology at 2.0 g/10 min melt flow index (2.16 Kg/190 oC) with the density of 0.9537 g/cm³.
In this situation, ASTM Designation E9-89 was applied for the slenderness ratio of polymeric materials, where the slenderness ratio, l/d (d = 12 mm) of the specimen is ~ 1.5.
HDPE/SD composites were tested under high strain rate of 650 s-1, 900 s-1, and 1100 s-1, respectively Results and Discussion: Strength and rigidity properties: Strength is commonly referred to the capability of a material to hinder the fracture under applied stress either at low or high speed [11], while rigidity of a material signifies the material’s ability to resist deformation.

To overcome this difficulty, the ceramic superconducting material is often put into a metal sheath and drawn into a thin composite wire [2,3].
This is understandable because EPR itself is an amorphous material.
Obviously, EPR is present in the grain boundaries of the composite material and still exists even after sintering at 600°C.
