for tensile strength of polymer composite which data should be

i have done tensile testing according to astm d638 for my polymer composite but im confused which data should be most of polymer composite (thermoset polymers) has brittle behavior so ultimate and tensile strength are very close to 

why does adding nanoclay in epoxy resin increase tensile strength

why does adding nanoclay in epoxy resin increase tensile strength but decrease flexural strength at 4 wt% of nanocaly hello i think you should check your composite curing content at 3 stages 1th: before adding nano clay 2th: after adding 

how does the filler material influence the mechanical behavior or

does adding the filler material increase the tensile strength and flexural strength compared to unfilled composites of course filler dramatically influence on mechanical properties of materials including tensile and flexural strength. as a rule 

[solved] how can the strength of composite material change in high

tensile strength of polyester composites reinforced with palf

therefore this work investigates the tensile properties of polymer matrix composites incorporated with up to 30 vol% of palf. the results show a significant increase in tensile strength and elastic modulus with the amount of fiber. increase in 

if strength increases does elongation also increase - researchgate

since the hardness increases with the increase in strength and increase in hardness led to increase in brittleness. when talking about composites the usual trade between tensile strength and elongation is that one grows while the other 

tensile strength of epoxi composites reinforced

matrix were subjected to tensile test. the results showed a significant increase in tensile strength and deformation of the composites as a function of the amount of fine fibers of sisal added. keywords: sisal fibers tensile strength composites.

how can i explain the decrease in tensile strength of a graphene

most of the research prove that graphene increase tensile strength and decrease elongation. . in general the bonding interactions between components of a composite makes them stiffen while the absence of any interaction or the presence 

effect of fiber loading and orientation on tensile strength of composites

1 that the tensile strength of the composites decreases with increase in fiber loading and orientation with few exceptions. this is because of poor adhesion between fiber and matrix. the maximum tensile strength is observed for composite with
