CONSULTING
From resin development to process stabilization,
we solve shop-floor problems with you.
Development delays, production defects and property variation in composite products mostly arise where the resin system and process conditions interact. JNC Composites Lab looks at materials and processes together, finds the cause, and proposes solutions that can be reproduced under real production conditions.
SERVICES
Consulting Areas
Resin System Development
We design thermoset resin formulations to suit your target properties and process.
- Formulation design for epoxy, vinyl ester and phenolic resins
- Curing agent and accelerator selection, and cure cycle design
- Verification of target properties such as viscosity, pot life and Tg
Prepreg · Towpreg
We establish manufacturing conditions that balance impregnation quality and handling.
- Design of tack, flow and shelf life
- Control methods for resin content and degree of impregnation
- Review of winding and unwinding processes and AFP suitability
Molding Process Optimization
We diagnose and improve the conditions of winding, pultrusion and RTM processes.
- Filament winding tension, viscosity and cure conditions
- Pultrusion die temperature zones and pull speed
- RTM and infusion resin flow, and countermeasures for dry spots
Defect Root-Cause Diagnosis
We find the root causes of voids, delamination, under-cure and property loss.
- On-site process review and sample analysis
- Forming cause hypotheses and running verification tests
- Proposing control criteria to prevent recurrence
Production Transfer · Scale-up
We help lab formulations deliver the same results on production equipment.
- Review of process variables when scaling up batch size
- Suitability evaluation for raw material substitution and localization
- Setting quality inspection items and criteria
Technical Advisory · Project Collaboration
We work with you from the R&D project and new product planning stages.
- Technical advice on material and process selection
- Technical collaboration on government and corporate research projects
- Regular technical advisory contracts
PROCESS
How We Work
