Analyze the collected data using XRD analysis software (TOPAS (Bruker),Origin Pro (OriginLab), ). The software helps identify and interpret the diffraction peaks present in the pattern. These peaks correspond to the arrangement of atoms within the crystal lattice and provide information about the crystalline structure, orientation, and phases present in the fibers or polymers. Compare the obtained diffraction pattern with known reference patterns from databases to identify the peaks and corresponding crystallographic planes. This helps determine the crystal structure, lattice parameters, and crystallinity of the fibers or polymers. Interpret the XRD results based on the observed peaks and patterns, considering the known properties of the fibers or polymers being analyzed. It's important to note that the specific details and techniques used in XRD analysis may vary depending on the equipment, sample characteristics, and research objectives.

Dear friend Gourab Roy

X-ray diffraction (XRD) is a powerful technique for analyzing the crystal structure of materials such as fibers and polymers. The XRD pattern provides information about the crystal structure of the material, including the orientation and spacing of the crystal planes (https://www.thermofisher.com/blog/materials/using-xrf-and-xrd-for-polymeric-characterization/).

To analyze your newly manufactured composite, you can use XRD software such as **Match!** or **Profex** to obtain the d-spacing and peak values from your XRD graph (https://cms.eas.ualberta.ca/xrd/sample-preparation/). However, you mentioned that these software tools are not able to properly match anything related to hydrocarbons of polymers or fibers. In this case, you may want to consider using a more advanced XRD analysis technique such as **small-angle X-ray scattering (SAXS)** or **wide-angle X-ray scattering (WAXS)**(https://www.thermofisher.com/blog/materials/using-xrf-and-xrd-for-polymeric-characterization/)

SAXS is used to analyze the size and shapes of polymer domains within a sample. It is particularly useful for analyzing polymer fibers and films for more advanced structural investigations ((https://www.thermofisher.com/blog/materials/using-xrf-and-xrd-for-polymeric-characterization/)). WAXS is used to determine the degree of polymer crystallinity in a sample (Article X-ray Diffraction Analysis and Electron Microscopy of the Ca...

first, you must obtain polycarbonate XRD patterns

secondly, you get the pattern of Your composite

and then final you check the d parameter between two compounds together

you can find differences between two compounds and return to the other paper to characterize these.

For XRD of fiber sample one apply on glass by using solvent .

1. By using origin pro software, you can find peak positions, crystallinity, size of particles in nm with modified Dybe scherrer equation, microstrain and stress, inter planer distance(d-spacing), FWHM.

2. You can also use Xpert high score software

2. VESTA software for visualisation of planes along x,y,z axis.

@Gourab Roy... Download Xpert Highscore XRD analysis software. Tutorials for using this software are easily available. Follow the procedure and you would get XRD pattern of sample as well as you can get comparative patterns and in the form of graph/peak lines. Also you can calculate many parameters such as average crystallinity,lattice strain etc very easily.

Few options:

1. Experimental Indexing: Instead of relying solely on existing databases, you can perform experimental indexing of your XRD pattern. This involves analyzing the peak positions, intensities, and shapes to identify characteristic patterns that may correspond to specific crystallographic planes. By comparing your experimental data with known diffraction patterns of various crystalline materials, you may be able to determine the planes present in your composite.

2. Simulation and Modeling: XRD simulation and modeling software can be used to simulate diffraction patterns based on known structural information. By inputting the structural details of the constituents of your composite (e.g., fiber material, polymer matrix), you can generate simulated diffraction patterns and compare them to your experimental data. This approach can help identify the planes and crystal structures that best match your XRD pattern.

3. Collaboration with Experts: Seek collaboration with experts in the field who have experience in analyzing XRD patterns of natural fiber composites or similar materials. They may be able to provide insights, guidance, or access to specialized databases or resources that can assist in identifying the planes present in your composite.

4. Additional Characterization Techniques: Consider employing complementary characterization techniques to gain a more comprehensive understanding of your composite's structure. Techniques such as scanning electron microscopy (SEM), transmission electron microscopy (TEM), or Fourier transform infrared spectroscopy (FTIR) can provide valuable information about the morphology, microstructure, and chemical composition of the composite, which can aid in determining the planes present.

Hope it helps
