This study numerically evaluates the fibre orientation state of a 20 wt.% short carbon fibre reinforced polyethylenimine fabricated by LAAM. The fibre orientation state of the solidified deposited bead is determined by a fully coupled flow/orientation simulation approach. The material properties of deposited composites are computed by assuming that the deposited bead has heterogeneous regions with varying local fibre orientation states. A finite element simulation is performed to model the LAAM process of a thin-wall structure, where the predicted inhomogeneous material properties are employed. Computed results show notable differences between simulations performed by employing homogenous properties and those obtained using heterogeneous properties. The bead-direction tensile stress contours computed under the heterogeneous assumption are comparable to experimental data in the literature, supporting our numerical approach.","PeriodicalId":20245,"journal":{"name":"Plastics, Rubber and Composites","volume":"13 1","pages":"435 - 456"},"PeriodicalIF":2.0,"publicationDate":"2023-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77271784","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}

Microstructural characterizations such as Fourier transform infrared spectroscopy (FT-IR), Field emission scanning electron microscopy (FE-SEM), thermogravimetric analysis (TGA), and X-ray diffraction (XRD) analysis were used to better understand the results. FT-IR results indicate chemical linkages forming between the epoxy resin and marble dust in the composite, while FE-SEM images suggest strong interfacial bonding between filler and matrix. TGA analysis shows enhancement of thermal properties with increasing filler content, while XRD indicates enhancement of crystallinity. Micro-mechanical modeling using the representative volume element (RVE) approach was also carried out using a commercial simulation package, determining Young’s modulus and comparing it with experimental results.

The emissions and energy consumption associated with the production of PVC have been significantly reduced by increasing the recycling rate.

Effects of resin temperature, CNT content, and the processing technique on the overall composite laminate quality were investigated by monitoring electrical properties of composite sheets. Epoxy/woven glass fibre composites loaded with various CNT contents were also manufactured using compression moulding and vacuum bagging techniques for comparison purposes. VI was achieved at two different temperatures (25°C and 50°C) to study the effect of variation in viscosity on CNT penetration during infusion. The results showed that electrical conductivity measurement was a very effective tool to assess the CNT penetration state of composite laminates in VI method. Both the resistive and capacitive behaviour in composite laminates due to filtration of CNTs at higher CNT contents was observed. However, the CNT penetration was improved by increasing the temperature of epoxy/CNT mixture before the infusion.","PeriodicalId":20245,"journal":{"name":"Plastics, Rubber and Composites","volume":"28 1","pages":"227 - 237"},"PeriodicalIF":2.0,"publicationDate":"2023-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80906611","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}

The GTR was treated using 10 wt-% NaOH solution and 1 wt-% stearic acid (SA) in acetone. The results showed that the GTR addition increased the water absorption and decreased the tensile strength and elastic modulus of epoxy composites. In dry condition, compared to the untreated GTR, the tensile strength of the treated GTR decreased by about 4.8% and 2.9% for the NaOH- and SA-treated GTR, respectively. Nevertheless, the addition of treated GTR increased the elastic modulus of epoxy composites by about 8.4% and 6.0% for the NaOH-and SA-treated GTR, respectively. For the aged epoxy, the tensile strength and elastic modulus decreased further due to the matrix plasticisation and degradation of the interface GTR/epoxy strength. It was found that the SA-treated GTR has better performance than the NaOH-treated GTR.","PeriodicalId":20245,"journal":{"name":"Plastics, Rubber and Composites","volume":"26 1","pages":"216 - 226"},"PeriodicalIF":2.0,"publicationDate":"2023-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83225518","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}

In this study, a nucleating system composed of 1,3:2,4-bis(3,4-dimethylbenzylidene) sorbitol (DMDBS) and tetrasilanolphenyl silsesquioxane (phPOSS) was used to modify isotactic polypropylene (iPP). Oriented films characterised by different draw drown ratios (4.8, 9.7, 14.5) were prepared and analysed. Their mechanical properties, coefficient of friction, thermal properties, and structure as well as optical properties such as gloss, haze, and transparency, were also determined. The macromolecular orientation of films was tested by polarised light Fourier transform infrared spectroscopy. The proposed nucleating system provides films with superior mechanical and optical properties, which are accompanied by high orientation ability. The application of DMDBS and phPOSS allowed a 26% increase in penetration load at break and Young modulus by 70% compared to iPP. It can be assumed that DMDBS/phPOSS system is an efficient modifier for polypropylene film production.","PeriodicalId":20245,"journal":{"name":"Plastics, Rubber and Composites","volume":"30 1","pages":"204 - 215"},"PeriodicalIF":2.0,"publicationDate":"2023-01-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75446378","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}

This paper introduces the patented concept of structural carbon fibre-reinforced polymer (CFRP) cores, intending to overcome limitations allowing for integral, yet complex designs. The hollow cores are initially manufactured and partially cured via resin transfer moulding (RTM) with inflatable rubber core. These cores are then integrated in a dry textile-based preform which is impregnated in another RTM process. Here, the cores stabilize the preform during injection and afterwards remain in the component as load-carrying elements. Thereby the partial degree of cure of the cores before the second RTM process is optmised to balance dimensional stability and bonding strength. The process route using structural CFRP cores was successfully applied to a generic structure and proven by structural testing.","PeriodicalId":20245,"journal":{"name":"Plastics, Rubber and Composites","volume":"3 1","pages":"407 - 417"},"PeriodicalIF":2.0,"publicationDate":"2022-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75389932","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}
