Epoxy Resin Composites

As an efficient reinforcing material in resin matric composites, the application of basalt fibers (BFs) in composites is limited by the poor interfacial adhesion between BFs and the resin matrix. In this study, to obtain the basalt fibers/epoxy resin composites with enhanced mechanical properties, the modification solution containing different concentrations of Lanthanum ions (La3+) was synthesized to modify the BFs surfaces to enhance the poor interfacial adhesion between BFs and the matrix. The morphology, the chemical structure and the chemical composition of the modified BFs surface were observed and detected by scanning electron microscopy, Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy, respectively. The results show that, after BFs were soaked in the modification solution, the more active groups (C=O, –OH, C–O, etc.) were introduced to the BFs surfaces and effectively enhanced the bond strength between BFs and the resin matrix. The obtained mechanical performances of prepared basalt fibers/epoxy resin composites showed that the tensile strength, bending strength and interlaminar shear strength (ILSS) were improved with the modified BFs, and reached to 458.7, 556.7 and 16.77 Mpa with the 0.5 wt.% La. Finally, the enhancement mechanism of the modification solution containing La element is analyzed.

To enhance the interfacial adhesion between carbon fibre and epoxy resin matrix, phenolic resin surface treatment agent has been carried out. The influence of phenolic resin treatment agent on interfacial adhesion of carbon fibre reinforced epoxy resin composites were investigated by interlaminar shear strength, atomic force microscopy, X-ray photoelectron spectroscopy and scanning electron microscopy. The results indicated that the interfacial adhesion was improved greatly after carbon fibre treated by phenolic resin surface treatment agent.

Lignin/epoxy resin composites were prepared by blending lignin with epoxy resin cured by polyamide. The effect of the content of lignin and polyamide on the mechanical properties of the lignin/epoxy resin composites was studied systemically. And the structure for the blend of lignin and epoxy resin without the curing agent was characterized by Fourier transform infrared spectroscopy (FTIR). The results of mechanical properties test showed that the bending strength of the composites decreases gradually with increasing the content of lignin, while the impact strength increased firstly and then decreased. The bending strength of lignin/epoxy resin composites showed a trend of increasing firstly and then decreasing with the increase of the content of polyamide, while the impact strength exhibited an opposite trend. The density for the composites increased with the addition of lignin, and polyamide exhibited an inconspicuous effect on density of the composites. The FTIR analysis results showed that the epoxy resin could be cured by lignin without polyamide, which concluded that the lignin could catalyze the cross-linking of epoxy resin or react with epoxy resin, and this bonding effect would beneficial to the properties of lignin/epoxy resin composites.

Flexural Tests

In this work, montmorillonite (MMT) nanoclay reinforced epoxy resin was prepared to study the effect of nano filler on tensile and flexural properties of its nanocomposite. MMT was first sonicated for 2 hours with an acetone where the ratio was 50 mL acetone: 1g clay. After being sonicated the clay was added to an epoxy resin matrix at 80 °C and mixed until the acetone was removed. Tensile and flexural tests were investigated to understand the effect of clay on the mechanical properties of MMT reinforced epoxy nanocomposite. In general, the mechanical properties of MMT/epoxy nanocomposites were slightly increased as the clay loading was increased up to 1 phr. However, for the amount of nanoclay more than 1 phr the result showed significantly decrease in mechanical properties. It was found that by adding the nanoclay up to 1 phr, the Young’s and flexural modulus increased around 6.75% and 6.61%, respectively. Since the nanoclay has higher elastic modulus as compared to epoxy resin, the addition of clay increased the modulus of its nanocomposites. On the other hand, at 2 phr of nanoclay the tensile strength, Young’s modulus, flexural strength and flexural modulus deceased around 44.12%, 17.24%, 17.84% and 10.77% respectively compared to pure epoxy. For more than 1 phr of filler the clay distributions might not be well dispersed and thus more agglomerations occurred in the composites. It can be concluded that, 1 phr of MMT filler was the optimum amount that can be reinforced with epoxy resin in term of tensile and flexural properties.

Epoxy Resin Composites

In this work we focused our attention on an innovative use of food residual biomasses. In particular, we produced biochar from coffee waste and used it as filler in epoxy resin composites with the aim to increase their electrical properties. Electrical conductivity was studied for the biochar and biochar-based composite in function of pressure applied. The results obtained were compared with carbon black and carbon black composites. We demonstrated that, even if the coffee biochar had less conductivity compared with carbon black in powder form, it created composites with better conductivity in comparison with carbon black composites. In addition, composite mechanical properties were tested and they generally improved with respect to neat epoxy resin.
