Pollution from plastic materials has become a severe problem all around the world. Plastics, due to their long lasting properties are utilized majorly in almost every application from packaging, electrical appliances, vehicle parts etc. the major concern related to plastics are that they are non-degradable and hence are harmful for environment. Several researches have been done in utilizing plastic material in addition with some other materials to form a composite material which has better properties than pure substances. Plastics with glass fibres are one such of composition where the new material formed can be used for several day to day applications. Hence the present work focuses on, manufacturing of a composite material from recycled glass fibres and recycled polypropylene co-polymers (PPCP) in varying ratios. A total of six specimens are made and results for Heat deflection temperature (HDT) 70:30 has the best results compared to other compositions. Results are also calculated for shear strength for the same composition of specimen, which shows better results compared to wood material (plywood). This experiment provides a solution for utilizing the waste plastic material found in waste lands and scrapyards which continuously pollute the environment.

The paper analyses the development and market potential of composite structure boards for the construction and built environment. The composite material is based on using recycled plastic reinforced with glass fibres. For some plastic materials, the Young modulus is relatively low and a sandwich structure built from plastic skin and foam core has to be used in order to achieve the required stiffness. The structural boards will be formed by a single one or two step moulding process instead of fabricated in a number of processes. The contens of the board has been optimised to reduce its weight and to enable it to be moulded from compounds using a high percentage of recycled plastics. Test samples have been tested at Nottingham Trent University (NTU) Civil Engineering laboratory to evaluate the influences of the type of plastic, the skin foam ratio and the percentage of glass fibres into the composite material mechanical properties.

The exploration of different materials is at its peak nowadays. This pace has not only gone towards discovering new material but inventing new, by making composites of different materials. Now this stream has gone into making composites of different polymers to make them suitable enough to compete and overtake metals. In this study, Polypropylene Copolymer (PPCP) is mixed with Glass Fibre Reinforced Polyester (GFRP) to form the Recycled PPCP or RPPCP. Further, a composite material is formed by the amalgamation of RPPCP and Recycled Glass Fibre (RGF) in different proportions. These samples of different proportions are created and tested in weatherometer and DSC analysis. In both of the tests, the outcome has been in favor of the sample with 70% RPPCP and 30% RGF proportion of the composite.

The objective of this paper is the vibroacoustic evaluation of an innovative material for a sports car roof, aiming at replacing fiberglass composite materials. Such evaluation was carried out using numerical and experimental analysis techniques, with cross-comparison between the corresponding results. The innovative material under analysis is a composite material, with a thermoplastic polypropylene matrix and reinforcement made of cellulose fibers. In order to validate the virtual dynamic modeling of the new material, the inertance on different points of some sheets made of the material under analysis was evaluated by an in-house made experimental activity, performed in the CRF (Fiat Research Center) test room, and cross-compared with corresponding results from a numerical analysis performed with the MSC Nastran software. Then, a realistic model of the car roof of the Alfa Romeo 4C car, made with the new material, was implemented and analyzed from the vibroacoustic point of view. The mere switch to the new material, with no changes in the geometry/structure of the car roof, did not allow preserving the original values of static rigidity, dynamic rigidity, and configuration of modal shapes. For this reason, a geometric/structural optimization of the component was performed. Once the new geometry/structure was defined, a vibroacoustic analysis was carried out, checking for a possible coupling between the fluid cavity modes and the structure car body modes. Finally, the vibroacoustic transfer functions to the driver’s ear node were assessed, considering two different excitation points on the structure. The excellent damping capacity of the proposed material led to an improvement in the vibroacoustic transfer functions and to a reduction in the weight of the pavilion.

Study of the Biodegrability of Degradable/Biodegradable Plastic Material in a Controlled Composting EnvironmentThe objective of this study was to determine the degrability/biodegradability of disposable plastic bags available on the market that are labeled as degradable/biodegradable and those certified as compost. The investigated materials were obtained from chain stores in the Czech Republic and Poland. Seven kinds of bags (commercially available) were used in this study. One of them was a disposable bag made of HDPE and mixed with totally degradable plastic additive (TDPA additive). Another was a disposable made of polyethylene with the addition of pro-oxidant additive (d2w additive). One was labeled as 100% degradable within various periods of time, from three months up to three years, and four were certified as compostable. The test was carried out in a controlled composting environment. The biodisintegration degree of the obtained pieces was evaluated following a modified version of ČSN EN 14806 Norm "Packaging - Preliminary evaluation of the disintegration of the packaging materials under simulated composting conditions in a laboratory scale test" and a modified version of ČSN EN ISO 20200 "Plastics - Determination of the degree of disintegration of plastic materials under simulated composting conditions in laboratory-scale test" (ISO 20200:2004). The emphasis was put on determination whether the bags are degradable/biodegradable or not.

Computational simulations of indentations in elastic-plastic materials showed overestimate in determining elastic modulus using the Oliver & Pharr’s method. Deviations significantly increase with decreasing material hardening. Based on extensive finite element computations the correlation between elastic-plastic material property and indentation has been carried out. A modified method was introduced for estimating elastic modulus from dimensional analysis associated with indentation data. Experimental verifications confirm that the new method produces more accurate prediction of elastic modulus than the Oliver & Pharr’s method.

Before And After

The significance of composite materials and their applications are mainly due to their good properties. This imposes the need for their recycling, thus extending their lifetime. Once used composite material will be disposed as a waste at the end of it service life. After recycling, this kind of waste can be used as raw materials for the production of same material, which raises their applicability. This indicates a great importance of recycling as a method of the renowal of composite materials. This study represents a contribution to the field of mechanical properties of the recycled composite materials. The tension mechanical properties (tensile strength and modulus of elasticity) of once used and disposed glass-epoxy composite material were compared before and after the recycling. The obtained results from mechanical tests confirmed that the applied recycling method was suitable for glass-epoxy composite materials. In respect to the tensile strength and modulus of elasticity it can be further assessed the possibility of use of recycled glass-epoxy composite materials.

Eco-paving block is a product used for construction consisting of sand and plastic mixes. In order to produce eco-paving blocks, the mixture of sand and concrete was substituted in part with sand and plastics. In order to properly mix plastics to create eco-paving blocks, a plastic smelter was used to generate heat and melt the plastic materials. The plastic material types used in this case was PETE or PETE, which has the characteristics of being flexible and high adhesive properties; along with ABS which can stand pressures. Based on the tests conducted with the plastic smelter using PET, ABS, and the combination of PET and ABS, the most promising result was shown with the combination of PET and ABS. This combination required 8 minutes 21 seconds for the plastics to become fully melted, and a temperature of 278oC. The combination of PET and ABS resulted in a mixture of plastics with strong adhesive properties and durability. This product could potentially be developed into eco-paving blocks. Additional studies regarding the optimum dosage combinations of PET and ABS plastics in eco-paving blocks can potentially be established in order to further optimize the usage of these plastics in eco-paving blocks.

Plastic waste has become a big issue in the world for its large amount of plastic waste in the sea. Most of the plastic waste is plastic packaging which consists of flexible and rigid plastic packaging. This research discusses flexible plastic packaging. Until now, most researches on the loss of plastic materials discuss how to manage plastic waste disposal once it has been used by community: only a few discuss production cycle: while none of them discusses flexible plastic packaging area. This research aims to examine the number of mismanaged materials throughout flexible plastic packaging life cycle using a combination of Material Flow Analysis (MFA) and Life Cycle Analysis (LCA). Based on the literature review, interviews and observations conducted by the author to all stakeholders in the life cycle of flexible plastic packaging, mismanagement of plastic material occurred in each cycle, mostly caused by quality degradation of flexible plastic that could cause plastic waste was not acceptable in the mechanical recycle. The results of this study show that: (1) mismanaged material occurred in all cycles throughout the life cycles of flexible plastic packaging, (2) quality degradation is the main caused of mismanaged material in several cycles, and (3) the mismanaged materials in the life cycle of flexible plastic packaging were 98.29%.
