Frequently Asked Questions

What is the shelf life of your prepreg, and what happens after expiration?

Our prepreg carbon fiber offers a 12-month shelf life at -18°C. Expiration means manufacturer's performance guarantee ends. While often usable after testing, critical carbon fiber parts require strict adherence. Proper inventory management and our carbon fiber supply chain support minimize waste.

Can I re-freeze thawed prepreg materials?

Yes, with documentation. Materials can be re-frozen if out-time limits aren't exceeded. However, repeated freeze-thaw cycles can impact carbon fiber properties and introduce moisture. Our technical support team advises minimizing re-freezing for optimal carbon fiber composite manufacturing.

Autoclave vs. Oven Cure: What's the difference for your prepreg?

Autoclave carbon fiber cure uses heat, pressure, and vacuum for superior void content (<1%) and mechanical properties. Out-of-autoclave prepregs achieve near-autoclave performance with only heat and vacuum. Standard prepreg in an oven reduces strength, so choose wisely for your carbon fiber manufacturing process.

How do I select between UD tape and woven fabric prepreg?

Choose unidirectional carbon fiber for high tensile strength in clear load paths on simpler geometries. Opt for woven carbon fiber fabrics where multi-directional loads or complex shapes requiring drapability are key. Our technical support guides optimal carbon fiber prepreg product types selection.

What environmental conditions are ideal for prepreg layup?

Maintaining 18-24°C and 35-65% humidity is crucial for carbon fiber fabrication. Proper conditions prevent prepreg carbon fiber tack issues, resin advancement, and moisture absorption, ensuring consistent carbon fiber properties and defect-free carbon fiber composite manufacturing.

What weight savings can I expect with your carbon fiber prepreg?

Switching from aluminum to our carbon fiber prepreg typically yields 40-60% weight reduction. Optimized structural carbon fiber designs leverage directional carbon fiber properties and part consolidation, dramatically enhancing the lightweight carbon fiber advantage for your application.

Can damaged carbon fiber prepreg parts be repaired?

Yes, carbon fiber reinforced polymer structures can be repaired using bonded patch methods, often with the original prepreg carbon fiber. While carbon fiber repairs are feasible, critical components require OEM-approved procedures and careful material selection to ensure structural integrity and longevity.

What certifications and test data do you provide?

Every carbon fiber prepreg shipment includes a Certificate of Conformance and material test reports. Detailed carbon fiber data sheets and traceability documentation link to carbon fiber manufacturing process records, ensuring full transparency and compliance for your carbon fiber supply chain.

How do you handle quality issues or material defects?

Our commitment to quality carbon fiber means swift action. Report any suspected defect immediately. We conduct a thorough root cause investigation, providing prompt technical support and resolution. Our carbon fiber manufacturing process boasts a <0.1% claim rate, ensuring reliability.
