Tensile modulus Terephthalic acid

A polyester first prepared by Jackson (3) (20 mol% modified p-hydroxybenzoic acid poly(phenyl-1,4-phenylene terephthalate)) was spun at 320°C and fibers were characterized "as-made". The dynamic tensile modulus as a function of DR is seen in Figure 4 and shows that very high values are obtained at even low DR-values. 

Premixing CNT with poly(ethylene terephthalate) (PET) in a solvent followed by melt spinning after drying the mixture Tensile strength of the composite fibers increased by 36.9% and the tensile modulus increased by 41.2% by adding 0.02 wt% of acid-treated MWCNTs Shen et al. [137]... 

PLA, also known as polylactide (i.e. polymerization of cyclic lactic acid, also called lactide), originally is a brittle material with lower impact strength and elongation at break, similar to another relatively brittle polymer—polystyrene (PS). However, its tensile strength and modulus are comparable to polyethylene terephthalate (PET). This is shown in Table 5. 2 as reported by Anderson et al (2008). Poor toughness limits its usage in...
