“…where V is the activation volume and p is the pressure. The dependence of rate of cure on temperature is significantly stronger than on pressure in the range 1-140 bar, which is observed during the curing process in the mold [42][43][44]. Therefore, the dependence on pressure will be ignored.…”

The influence of the representative volume element (RVE) size (in terms of fiber packing and number of fibers for a given fiber-volume fraction) on the residual stresses created during the curing process of a continuous fiber-reinforced polymer matrix tow is investigated with the ultimate goal of finding a minimum unit cell size that can be used later for a homogenization procedure to calculate the response of woven fiber textile composites and in particular, fiber tows. A novel network curing model for the solidification of epoxy is used to model the curing process. The model takes into account heat conduction, cure kinetics and the creation of networks in a continuously shape changing body. The model is applied to the curing of a fiber/matrix RVE. The results for the minimum size of the RVE, obtained on the basis of the curing problem, are compared with a similar RVE, modeled as an elastic-plastic solid subjected to external loads, in order to compare the minimum RVE sizes obtained on the basis of different boundary value problem solutions.

“…Sheet moulding compounds (SMCs) are composite materials that, due to their mechanical and aesthetical properties have been employed in a large numbers of applications from sport and automotive to building applications. 1 However, despite their numerous advantages there are some drawbacks associated with glass fibres used in SMC composites. They are non-renewable and give problems with respect to ultimate disposal at the end of a materials lifetime since they cannot be completely thermally incinerated and leave behind a residue that can damage the incineration furnace.…”

Hemp fibre mat reinforced polyester composites were fabricated using a conventional sheet moulding compound (SMC) process. The influence of fibre and CaCO 3 filler content on strength and stiffness of the HF-SMCs is reported and compared with data for chopped glass fibre reinforced sheet moulding compounds (GF-SMCs). In addition the influence of alkaline and silane treatments of the hemp fibres is evaluated. The experimental data is compared to modified versions of the Cox-Krenchel and Kelly-Tyson models, supplemented with parameters of composite porosity to improve the prediction of composite tensile properties. A good agreement was found between the modified models and experimental data for strength and stiffness. The results indicate that HF-SMCs are of interest for lowcost engineering applications that require high stiffness to weight ratios.

“…The speed of the support film controls the percentage of fiber. For this purpose, synchronization between the translation speed of support film and fiber chopping can be set up [31]. Resin paste from side-B is laid above chopped fiber in the downstream direction, which creates a sandwich pattern of resin and fiber which is further passed through a roller set, thereby compressing the resin and fibers, hence wetting the chopped fibers with resin.…”

Composites have recently emerged as the ideal material for weight reduction in a wide range of technical applications. Hybrid composites offer special properties that enable them to meet a wide range of design objectives more efficiently and affordably than conventional composites. Natural fiber-based hybrid composites are also less damaging to the environment and have a reduced carbon footprint. The hybridization of natural fibres with synthetic fibres can substantially minimise the problems associated with natural fibre composites, since the advantages of one kind of fibre can outweigh the disadvantages of another. Several research have been carried out to investigate the different characteristics of carbon-natural fibre reinforced hybrid composites and to evaluate their suitability for a variety of technological applications. The objective of this work is to provide an overview of the materials and manufacturing processes currently utilised to fabricate carbon-natural fibre reinforced hybrid composites. This paper also attempts to discuss the reported mechanical, damping, and other characteristics of the resultant hybrid composites. This article provides a factual overview of the development accomplished so far in the field of hybrid composites constructed from carbon-natural fibres.
