“…The crystallization process plays a crucial role in determining various properties of a semi-crystalline polymer. of neat PP was observed to be at 109.91 C similar to previous reports, [12] while all the hybrid samples exhibited a higher T c of 10 C more than PP as seen in Table 3.…”

“…[10,11] The addition of different fillers into a polymer matrix as discussed previously for hybrid composites, creates hindrance or eases the mobility of polymeric chains, and thereby, affects their rheological behavior and subsequently, the processing parameters. [12] On the other hand, apparent changes in thermal and thermomechanical properties such as thermal stability, glass transition temperature, crystallization temperature, thermal conductivity, storage, and loss modulus, and so on, in comparison to the pure polymer may also be observed with addition and variation of filler content within a polymer matrix. [1,2,8,9] Among these aforementioned properties, composite density and thermal conductivity may make polymer composites indispensable for applications in different fields related to thermal management.…”

This study reports the preparation of multifunctional hybrid composites based on polypropylene (PP) for potential thermal management applications in automotive. Short carbon fiber (CF) at 5 and 8 wt%, and silane-treated hollow glass microsphere (HGM) at 5, 10, 20, 30, and 40 wt% were incorporated separately in PP along with maleic anhydride-grafted-polypropylene (MA-g-PP). The interplay of filler content and its dispersion and distribution had a significant effect on the thermal conductivity (K c) of the composites. Highest K c of 1.20 W/m K was obtained for a CF and HGM wt% of 5 and 20, respectively. The rheological analysis revealed improved flowability as the complex viscosity of composites up to 20 wt% of HGM content was found to be less than PP. The thermal stability improved upon HGM incorporation and the highest thermal stability of 26 C higher than that for PP was exhibited by hybrid composite with 8 wt% CF and 40 wt% HGM. Furthermore, Nielsen model demonstrated to be the closest fit for the experimental thermal conductivity value of hybrid composites among various micromechanical models used.

“…For instance, Lee et al [ 14 ] found that the incorporation of HGBs has a synergistic effect on improving the mechanical properties and decreasing the density in sheet moulding of a fibre-reinforced composite. Rupam et al [ 15 ] observed a consistent density reduction with increasing HGB content and an improvement in tensile strength in a polypropylene composite containing up to 5 wt% of HGBs. They also reported a continuous increase in hardness but observed a reduction in impact strength.…”

A Study of Physico-Mechanical Properties of Hollow Glass Bubble, Jute Fibre and Rubber Powder Reinforced Polypropylene Compounds with and without MuCell® Technology for Lightweight Applications

Lightweighting is one of the key solutions to reduce the carbon footprint of vehicles. Nowadays, it is still challenging to achieve this target because there is a conflict between the cost and final material performance, as well as the fact that many lightweight solutions are restricted to laboratory or small-scale production. In this work, a commercially feasible strategy was adopted to fabricate materials for lightweight applications. Hollow glass bubbles, jute fibres, and rubber powder were used as fillers with polypropylene as the base polymer. Various samples were fabricated using conventional and MuCell® injection moulding. Their performance was then characterised by their density and morphological, mechanical, and rheological properties. A comparison among hybrid fillers/polypropylene compounds with and without MuCell® technology was investigated. The filler hybridisation resulted in not only a density reduction of up to approximately 10%, but also improved tensile/flexural modulus and strength. The use of MuCell® led to a further reduction in density of roughly 10%. Meanwhile, although some compounds fabricated by MuCell® exhibited some deterioration in their tensile yield strength, tensile modulus, and impact strength, they maintained acceptable mechanical properties for automotive applications.

“…A similar trend was reported elsewhere and the phenomenon was explained with two contradictory effects of nucleation, which are not always obvious, and the reinforcement induced anti-plasticization effect. 46,47 At a relatively low filler concentration, such as 5 wt% and 10 wt%, owing to the heterogeneous nucleation effect, there is a rise in the degree of crystallinity upon increasing the rate of crystallization in PCL5 and PCL10. On the other hand, the PCL chain movements are restricted by the reinforcing effect of the biofillers and this limits its ability to arrange itself into a regular pattern.…”
