“…Juntuek et al [27] showed that the impact strength of PLA blends with 10 wt% NR was two times higher than that of neat PLA. Similar behavior was also found in ENR blend with other polymers such as poly(vinyl chloride) [10] and nylon 6 [16], and NR blend with poly(ethylene terephthalate) [28]. The impact strength of ENR/PLA blends as a function of ENR content is illustrated in Fig.…”

“…8 One of the methods used by many researchers is by the addition of a rubbery content into the uncured epoxy resins. According to Phinyocheep et al, 9 the mechanical properties of polyethylene terephthalate can be improved by the addition of natural rubber, while Abu Bakar et al 10 and Tan et al 11 use liquid epoxidised natural rubber (LENR) to improve the mechanical properties of epoxy composite. In this report, LENR was used as the toughening agent for the epoxy matrix.…”

The hybridisation of natural fibre with glass fibre provides a method to improve the mechanical properties instead of using the natural fibres alone. This research is focused on the hybridisation of glass/kenaf fibre with the addition of liquid epoxidised natural rubber to enhance the desired mechanical properties of the composite by reducing the synthetic fibre usage and encourage the natural fibre consumption. Liquid epoxidised natural rubber was added to the epoxy matrix in order to improve its mechanical properties whilst E-glass fibre and kenaf bast fibre were used as the reinforcement in the composite. Liquid epoxidised natural rubber (3%) was added as a toughening agent. Two types of kenaf fibre were prepared -untreated and treated with 6% NaOH -whilst the glass fibre was treated using a silane coupling agent. The flexural test, Izod impact test, environmental stress cracking resistance analysis and scanning electron microscopy analysis were performed to determine the effect of fibre treatment and liquid epoxidised natural rubber addition on the mechanical properties of the hybrid fibre-reinforced composite. It was found that the treatment and the addition of liquid epoxidised natural rubber contribute to the increment of the impact strength by 40% whilst the flexural properties recorded a 13% and 15% increment for both flexural strength and flexural modulus, respectively. The environmental stress cracking resistance analysis showed that the composites are more affected in acid medium followed by base medium and then with the control medium (air). The addition of liquid epoxidised natural rubber seems to improve the stability of the samples in the medium initially but tends to decrease rapidly over time due to debonding of the rubber particles.

“…6 Furthermore, using the cross polarization time and T 1q H, the relationship between morphology and mechanical properties was revealed for poly(ethylene terephthalate) with natural rubber. 7 On the other hand, solid state NMR studies on poly(L-lacide) (PLA) in ''fiber form'' are very limited; to our knowledge, only the draw direction of PLA films has been investigated by solid state 13 C NMR to date. 8 In regard to ''materials'' based on PLA, however, solid state 13 C NMR analyses and relaxation time measurements are also effective for structural and molecular motion analyses, since PLA has multiple components, including the crystalline and amorphous phases.…”

A random copolymer based on poly(L-lactide) (PLA) with poly(e-caprolactone) (PCL) was prepared and characterized by mechanical testing and solid state NMR, compared with a polymer blend. For a monofilament sample consisting of PLA/PCL random copolymer, there were negative correlations between the CL content and the mechanical properties: tensile strength, tensile elastic modulus, flexural rigidity, and flexural hysteresis decreased with increasing CL content. In contrast, the mechanical properties of the polymer blend were only slightly changed by addition of the CL unit. For the random copolymer, the addition of a small amount of CL reduced relaxation times, T 1 C and T 1q H, gradually. The T 1 C and T 1q H values correlated closely with the tensile elastic modulus and the tensile strength, respectively.
