The incorporation of mercerized fibers to polymeric matrices generated materials with an elastic modulus superior to that of LDPE and tensile strength values close to that of LDPE. The biodegradation rates of the polymer composites increased the addition of fibers. However, alkali-treated fibres had a less pronounced effect biodegradation rates of the polimeric composites, due to the lower tendency of mercerized fibers to absorb water.

As ZDMA increased, the ionic crosslink density of the blends gradually increased. Optimum tensile and tear strength of the compound were observed at 12.5 phr of ZDMA. At 5 and 7.5 phr of ZDMA, the blends showed significant good healing efficiency, supported by the characterization tests such as scanning electron microscopy (SEM) and manual video measuring machine (VMM). Fourier-transform infrared spectroscopy (FTIR) analysis showed the presence of ZDMA in the blends. The dynamic ionic bond of ZDMA contributed to the self-healing properties in the blends.

This work aimed for a constant melt-front velocity inside the cavities with varying geometries. Three methods of reservoir designs were considered: first, using engineering intuition, second and third, using mass balance and mass and momentum balance equations, respectively. Eight reservoirs were designed and compared to two no-reservoir cases. For each case, 27 runs covering three levels of fill-rate, F/P, and packing pressure were simulated, resulting in 270 simulation runs. The quality variables of flow and thermally induced retardation and the average and standard deviation of volumetric shrinkage were considered and for each parameter, the minimum, best cases, occurred with a reservoir case. Thus, this study offers a proof-of-concept design for using reservoirs to improve molding of small, high-precision optical parts.","PeriodicalId":20245,"journal":{"name":"Plastics, Rubber and Composites","volume":"15 1","pages":"330 - 345"},"PeriodicalIF":2.0,"publicationDate":"2023-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88613903","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Stress propagation altered the graphitic domains of the carbon black that fill the matrix and induced shifts in position, changes in width, and intensity of the D and G bands.

As the vulcanisation time increases, the tensile strength first increases and then decreases, and the elongation at break changes with the vulcanisation time on the contrary.
