Start with the engineering decision
The Chinese TDS identifies XK52 with a typical density of 52±5 kg/m3, room-temperature compression strength of 1.0 MPa, compression modulus of 44 MPa, tensile strength of 1.7 MPa, tensile modulus of 74 MPa, and 130°C compression strength of 0.71 MPa. The document states that values are for reference and are not guaranteed values. That disclaimer is essential: the values organize an early selection discussion but do not replace the applicable project document.
Translate the component into a controlled core brief
An XK52 request should identify whether the part is a flat sandwich panel, a curved shell, a drilled or grooved insert, or a complex CNC-prepared core. Thickness, skin construction, core form and the controlling drawing affect the practical meaning of a density-class request. A supplier cannot determine the final core geometry from an XK52 label alone.
Connect the material question to the process route
Single-test reports provide useful context when their conditions remain visible. Two room-temperature XK52 compression samples recorded 1.14 MPa at 50.92 kg/m3 and 1.18 MPa at 52.17 kg/m3. These are single-test sample results, not a guaranteed product range. The RFQ should also state the process temperature, pressure path, resin system, holding conditions and inspection questions.
Keep technical evidence within its stated boundary
Treat a technical table as a controlled decision record. Record the source document, issue date, grade name, test method, specimen orientation if relevant, temperature and test rate. When a buyer needs a release value, the correct next step is to request the applicable grade datasheet and agree the project’s acceptance method rather than turning a website number into a universal specification.
Related questions
Questions that make the next engineering conversation more useful.
01Are XK52 sample-test values a product guarantee?
No. The reported XK52 sample values are single-test results under stated conditions. Final requirements must be confirmed against the applicable datasheet and project acceptance criteria.
02What should be included with an XK52 enquiry?
Include the component, thickness, drawing or CAD package, manufacturing route, temperature context, quantity, and the specific value or document that requires confirmation.
