Puncture resistance and characterization of coated natural rubber latex (NRL) ultra high modulus polyethylene (UHMPE) upon heat ageing / Anisah Abdul Latiff

This study focuses on the effect of heat ageing towards the puncture resistance of coated natural rubber (NR) latex unidirectional (UD) ultra high modulus polyethylene (UHMPE) fabric. The application of NRL was done by dipping method namely single dip (SD), double dip (DD) and triple dip (TD). Heat...
