HDPE/graphene (a) typical stress-strain curves, (b) tensile modulus
, (c) tensile strength, and (d) elongation at break as a function of the graphene content.
Overall, the tensile property values indicate that POSS co-agents help to increase crosslink density of peroxide cured HNBR and increase tensile modulus
with an acceptable level of decreased elongation.
(3) The differences in tensile modulus
possibly originated by different local strain variations occurring at the surface of the specimen.
Figures 1-5 show mechanical properties such as tensile strength, tensile modulus
, and elongation at break, bending strength, and bending modulus of magnesium oxide (MgO) and aluminum oxide ([Al.sub.2][O.sub.3]) and phosphoric acid ([H.sub.3]P[O.sub.4]) fire retardants treated short jute fibers composites.
5: Tensile Strength and Tensile Modulus
of CSP/CR biocomposite at different Particle loading.
The tensile modulus
was increased with increasing concentration of wood fibers.
Both composites also showed a decrease in tensile modulus
, flexural modulus, and storage modulus with successive recycling, while they exhibited an increase in failure strain, coefficient of thermal expansion, and melt flow index.
Figure 6(b) shows the case of tensile modulus
. Since glass fibres are stiffer than wollastonite, modulus was observed to increase with the 100% relative volume of glass fibre and as wollastonite replaces glass fibre partially, composite modulus decreases with increasing relative wollastonite volume fraction.
Calculated tensile modulus
equal to 3.10 GPa of neat epoxy and (1) yields the CNT/epoxy composite tensile modulus
of 3.46 GPa at 0.25 wt% CNT loading, which translates to a 11.61% increase over the neat epoxy modulus.
where [E.sub.1] and [E.sub.t] are composite longitudinal and transverse moduli of a unidirectional short fiber-reinforced composite, rh and tit are the length efficiency factors, [V.sub.f] and [E.sub.f] are the fiber volume fraction and the fiber tensile modulus
, Em is the matrix tensile modulus
, and I/d is the fiber aspect ratio.
This two-part system features adhesion with a lap shear strength exceeding 4,600 psi, a peel strength surpassing 40 pli, a tensile modulus
of more than 410,000 psi and a flexural strength of over 13,000 psi.
