Manufacture of Polyester Composite BQTN 157-EX with a Reinforcement of Bentonite and Surfactant Cetyl Trimethyl Ammonium Bromide (CTAB)

The development of composite materials has become increasingly important in various industries, including construction, automotive, and aerospace. Composites are materials made from two or more constituent materials with significantly different physical or chemical properties. In this study, we focus on the manufacture of polyester composite BQTN 157-EX with a reinforcement of bentonite and surfactant cetyl trimethyl ammonium bromide (CTAB). Bentonite, a type of clay, is used as a filler material to improve the mechanical properties of the composite, while CTAB, a surfactant, is used to modify the structure and nature of bentonite to make it more compatible with the organic polymer material.

The main matrix of the composite is BQTN 157-EX polyester resin, a widely used material in various industries. Bentonite, an inorganic material, is used as a filler to improve the mechanical properties of the composite. CTAB, a surfactant, is used to modify the structure and nature of bentonite to make it more compatible with the organic polymer material. The process of making this composite involves the treatment of bentonite to increase its characteristics to be more in accordance with organic polymer material and provide hydrophobic properties.

Bentonite Processing

Bentonite processing is carried out to modify its structure and nature. The D-Spacing of bentonite before the measured CTAB treatment is 1,142 Nm, and after treatment, D-Spacing becomes 1,571 Nm. This shows that the part of the ammonium alkyl was successfully interested in the commercial bentonite layer. The treatment of bentonite with CTAB is an important step in making the composite, as it allows the bentonite to interact with the polyester resin and improve the mechanical properties of the composite.

Characterization of Composites

The characterization of composites is an important step in understanding their properties and behavior. In this study, we use various techniques to characterize the composites, including Microscopy Electron Scanning (SEM), Fourier Transform Infrared Spectroscopy (FTIR), and tensile testing. The results of these tests show that the addition of bentonite improves the mechanical properties of the composite, including its tensile strength, elongation, and thermal resistance.

The results of this study show that the addition of bentonite improves the mechanical properties of the composite. The tensile strength of the composite is 196.57 MPa, which is much higher than that of pure polyester resin (104.92 MPa). The elongation of the composite is 24%, which is also higher than that of pure polyester resin (13.32%). The thermal resistance of the composite is slightly faster than that of pure polyester resin, but this is not a significant drawback.

The SEM images of the composite show that the structure consists of random aggregates due to intercalization in the matrix. The FTIR analysis shows that the functional groups in each particle size and bentonite concentration are almost entirely compatible with pure polymers, indicating that the composite has a good compatibility in its structure and nature.

In conclusion, this study shows that the addition of bentonite improves the mechanical properties of the composite. The use of CTAB to modify the structure and nature of bentonite is an important step in making the composite. The results of this study have implications for the development of composite materials in various industries, including construction, automotive, and aerospace. Further development of this composite can contribute to broader industrial applications and increase material efficiency in various fields.

Future work in this area could involve the development of new composite materials with improved mechanical properties. This could involve the use of different types of fillers or the modification of the structure and nature of bentonite using different surfactants. Additionally, the study of the thermal resistance of the composite could be further investigated to determine the optimal conditions for its use in various applications.
