“…It was observed that in all the specimen under with the 20% of waste additive, the flexural and tensile properties were close to those of reference PP/FG composite without waste additive. Mechanical properties of a composite mainly depend on the fiber ratio, individual properties of fiber and polymer matrix and interfacial bonding of them (17,18). Besides that, it can be said that the aspect ratio of fibers is the major factor in deciding and affecting the mechanical properties of the composites.…”

“…PP/FG composites are mostly favored in the developing automotive industry due to the need for lightweight and high mechanical strength. E-type glass fibers are used in a wide range of development studies of PP composites (16)(17)(18)(19)(20)(21). In glass fiber reinforced PP/ FG composites, the process generally uses E-type glass fibers, long and short fibers in shape depend-ing on their mechanical expectations.…”

This study presents the preparation of short glass fiber reinforced polypropylene (PP/FG) composites using with waste (post-consumer) polypropylene composite containing long glass fiber (PP/LFG) obtained from the recycling of battery covers of trucks. Waste PP/LFG composite parts were mechanically grinded before adding to PP/FG composites. An injection molding machine was used to produce the PP/FG composite test samples loading with recycled waste PP/LFG composite in the range of 1-20% by weight. Effects of recycled waste PP/LFG content on the mechanical, thermal, and morphological properties of the PP/FG composites were investigated. The following three different tests, at various waste PP/LFG ratios, were conducted: Izod/Charpy Impact test, bending test, and tensile test. Mechanical test results showed that mechanical strength of prepared PP/FG composites were not influenced by content of waste PP/LFG material up to 10 wt.%. Differential scanning calorimetry (DSC) was used for the evaluation of thermal parameters such as melting point and crystallization temperature of the polymer matrix in the composites studied. Furthermore, by analyzing the values of thermal effects determined using the DSC method, it was possible to determine the degree of crystallinity. The DSC results showed that crystallinity %, melting, and crystallization temperatures of PP/FG composites were not influenced to adding waste PP/LFG at different ratios. The morphology of composite materials was investigated by SEM analysis. Good fiber dispersion was observed in the PP matrix for PP/FG composites containing short glass fiber prepared with all ratios of recycled waste PP/LFG material containing long glass fiber.

“…Remarkable efforts have been put in to develop fiber sizing agents for interfacial modifications of GF-PP composites, especially in high-end applications, since a practicable sizing agent can directly build a robust and efficient coupling interface between GF and PP, enabling effective stress transfer between fiber and matrix. 22 Nevertheless, due to the inherently distinct physical and chemical properties of the fiber and matrix, it is always challenging to create a highly compatible interface between the hydrophilic glass fiber and the hydrophobic PP. 23 Protection of the glass fiber filaments from breakage or disintegration is an important issue either during the manufacturing of glass fiber or during composite production.…”

“…However, some of these fibers interrupt the homogeneity of the resin matrix due to poor interaction with the resin, which negatively affects the mechanical properties.

In this study, a preliminary finding is carried out to obtain the optimum E-glass fiber content in polypropylene (PP) plastic products using loadings of 5, 10, 20, 30, and 40 wt%. The formulation with the optimum loading of 10 wt % glass fiber was reprocessed 10 times via extrusion and compression molding techniques to simulate actual recycling and impacts on service life properties such as mechanical, toughness, chemical, thermal, composition, and morphology. In the result, mechanical properties were lost after each reprocessing without effect on the chemical properties and elemental compositions. The thermal studies showed a decrease in degradation temperatures with the onset degradation temperature (T Onset ) for the one-time reprocessed PP recorded at 336.93 C with a maximum rate of weight loss (T Max ) at 427.68 C which further reduced to 259.90 C (T Max of 388.47 C) after 10 extrusion run showing onestep decomposition patterns. This work provides that glass fiber-reinforced plastics should not be reprocessed beyond 3 times except when refreshed with the addition of virgin PP to make up for the lost property. This will be very useful for manufacturers who want to simultaneously save costs (retain profit margin) and maintain the environment.

“…Sizing agent is an indispensable functional material in the papermaking additives. During industrial production, most of the paper and cardboard need to be sized for achieving the standard of physical properties and water resistance in the daily application. − According to the physical and chemical requirements of the paper and cardboard, the types of sizing agents used are also various such as natural polymer-based sizing agents (e.g., modified starch, carboxymethyl cellulose, and gelatin) and synthetic sizing agents (e.g., carbon fiber reinforced polymers, alkenyl succinic anhydride, and polyurethane). ,− However, such types of sizing agents still have inadequacies such as high manufacturing cost, insufficient physical and mechanical properties of paper, and low retention rate of precipitated calcium carbonate (PCC). − It is well known that PCC, as an irreplaceable low-cost filler in papermaking, can not only improve the printability of the paper but also reduce the energy consumption of the paper machine for drying . Moreover, based on the requirement of PCC retention rate in paper, research on the modification of PCC has gained great interest in the industry.…”

Functional papermaking additives have tremendous potential for application in multipurpose paper. In this research, a functional paper internal sizing agent based on waterborne polyurethane-grafted collagen hydrolysate (WPUC) was first prepared via free-radical emulsion polymerization of vinyl monomer-modified collagen hydrolysate and waterborne polyurethane (WPU). Then, the prepared WPUC was used as an internal sizing agent for sustainable processing and manufacturing of the handsheets. FTIR, XRD, DSC, and other analytical techniques were used to characterize the behavior and effects of WPUC internal sizing on the handsheets. The research found that the tensile coefficient, the tear coefficient, the folding resistance, and Cobb60 of the handsheets reached 55.8 N.m.g–1, 1.9 mN.m2.g–1, 12 times, and 190 g/m2, respectively, when the WPUC sizing agent was 2% in the pulp. In addition, when the precipitated calcium carbonate (PCC) and WPUC were incorporated in the pulp, the retention rate of PCC could be greatly increased without affecting the mechanical properties of the finished paper. Specifically, when the PCC dosages were 25 and 50% in the papermaking, the PCC retention rate of handsheets with the WPUC sizing agent increased correspondingly by 139.2 and 174.5%, respectively. Moreover, the handsheets had good water resistance. The results indicate that the WPUC is expected to be used as a novel paper internal sizing agent to further improve the paper performance as well as lower the production costs.
