Abstract

Woven fabric carbon fiber/epoxy composites made through compression molding are one of the promising choices of material for the vehicle light-weighting strategy. Previous studies have shown that the processing conditions can have substantial influence on the performance of this type of the material. Therefore the optimization of the compression molding process is of great importance to the manufacturing practice. An efficient way to achieve the optimized design of this process would be through conducting finite element (FE) simulations of compression molding for woven fabric carbon fiber/epoxy composites. However, performing such simulation remains a challenging task for FE as multiple types of physics are involved during the compression molding process, including the epoxy resin curing and the complex mechanical behavior of woven fabric structure. In the present study, the FE simulation of the compression molding process of resin based woven fabric composites at continuum level is conducted, which is enabled by the implementation of an integrated material modeling methodology in LS-Dyna. Specifically, the chemo-thermo-mechanical problem of compression molding is solved through the coupling of three material models, i.e., one thermal model for temperature history in the resin, one mechanical model to update the curing-dependent properties of the resin and another mechanicalmore »« less

Development of rCF Thermoplastic Non-woven Prepreg for Automotive Class A Body Panels via Compression Molding

Technical Report Bouguettaya, Mohamed ; Cieslinski, Mark ; Campbell, Don ; ...

One of IACMI’s stated goals is the recycling of composites into useful products. To achieve this, the institute plans to demonstrate recycling technologies at a sufficient scale to justify the investment risk for private industry commercialization. Success will mean the reduction of regulatory disposal risks, encouraging additional investment and will allow for the opening of new composite markets. This is a particular concern as failure to achieve this could mean the loss of US global competitiveness in the composites marketplace as US manufacturers become unable to meet increasing regulatory burdens surrounding composite waste disposal nor are able to compete withmore »« less

Static and Dynamic Mechanical Properties of Graphene Oxide-Incorporated Woven Carbon Fiber/Epoxy Composite

Journal Article Adak, Nitai Chandra ; Chhetri, Suman ; Kim, Nam Hoon ; ... - Journal of Materials Engineering and Performance

This study investigates the synergistic effects of graphene oxide (GO) on the woven carbon fiber (CF)-reinforced epoxy composites. The GO nanofiller was incorporated into the epoxy resin with variations in the content, and the CF/epoxy composites were manufactured using a vacuum-assisted resin transfer molding process and then cured at 70 and 120 °C. An analysis of the mechanical properties of the GO (0.2 wt.%)/CF/epoxy composites showed an improvement in the tensile strength, Young’s modulus, toughness, flexural strength and flexural modulus by ~ 34, 20, 83, 55 and 31%, respectively, when compared to the CF/epoxy composite. The dynamic mechanical analysis of the composites exhibitedmore »« less

Meso-scale modeling and damage analysis of carbon/epoxy woven fabric composite under in-plane tension and compression loadings

Journal Article Zhou, Guowei ; Sun, Qingping ; Li, Dayong ; ... - International Journal of Mechanical Sciences

The mechanical properties and damage behaviors of carbon/epoxy woven fabric composite under in-plane tension and compression are studied at the meso-scale level through experiment and simulation. An efficient representative volume element (RVE) modeling method with consistent mesh, high yarn volume fraction and realistic geometry is proposed. The material constitutive laws with plasticity, tension-compression asymmetry and damage evolution are established for the three components - yarn, matrix and interface, respectively. Significantly different mechanical properties and damage evolutions are observed depending on loading conditions and initial geometry characteristics. It shows a non-linear stress-strain curve with clear transition region and intensive damage inmore »« less

Properties of multiaxial and 3-D orthogonal woven carbon/epoxy composites

Book Bilisik, A K ; Mohamed, M H

A new three-dimensional multiaxial weaving technique was developed at NCSU. Rectangular cross-sectional preforms were fabricated. The preforms have five sets of yarn: these are warp, filling, Z-yarn and {+-}45{degree} yarns. The preforms which are made from carbon fibers were consolidated by vacuum impregnation molding at N.C. A and T State University. Epoxy/resin was used as the matrix. The unit cell of the multiaxial 3-D woven structure has been described. Mechanical tests were carried out on multiaxial 3-D woven and orthogonal woven carbon/epoxy composites. The tests included bending, interlaminar shear and in-plane shear. Test results for both structures were compared andmore » are presented.« less
Experimental Characterization and Numerical Modeling of the Interaction Between Carbon Fiber Composite Prepregs During a Preforming Process

Journal Article Zhang, Weizhao ; Ma, Xuan ; Lu, Jie ; ... - Journal of Manufacturing Science and Engineering

We report carbon fiber reinforced composites have received growing attention because of their superior performance and high potential for lightweight systems. An economic method to manufacture the parts made of these composites is a sequence of forming followed by a compression molding. The first step in this sequence is called preforming that forms the prepreg, which is the fabric impregnated with the uncured resin, to the product geometry, while the molding process cures the resin. Slip between different prepreg layers is observed in the preforming step, and it is believed to have a non-negligible impact on the resulting geometry. Thismore »« less
