Making a Nylon - Fibre Composite

Click For Summary
SUMMARY

The discussion centers on designing a nylon-fibre composite for a 3-point bending test, with a maximum deflection of 15mm and a load capacity of 5kN. The user seeks effective adhesion methods for fibres to nylon, specifically inquiring about the use of epoxy and the possibility of melting nylon to incorporate fibres. It is confirmed that nylon, being a thermoplastic, can be melted and solidified with fibres. Epoxy resins are recommended for their strong adhesion properties to various fibres, including glass fibre, making them suitable for DIY composite projects.

PREREQUISITES
  • Understanding of nylon thermoplastics
  • Knowledge of epoxy resin properties
  • Familiarity with composite material design
  • Basic skills in DIY moulding techniques
NEXT STEPS
  • Research the properties of glass fibre reinforced epoxy resin composites
  • Explore techniques for melting and solidifying nylon with fibres
  • Learn about the use of hempsilkotton as a reinforcement material
  • Investigate DIY moulding methods for composite fabrication
USEFUL FOR

Engineers, materials scientists, DIY enthusiasts, and anyone interested in composite material design and testing.

Hi, I was tasked to design a composite material that will undergo a 3 point bending test. Maximum deflection will be of 15mm and a maximum load of 5kN. The scope of this task is not to prevent failure but to analyse the composite and learn from the design process. Nonetheless the composite should sustain a reasonable load in relation to the given criteria.

To do this I came up with the idea of a fibre and nylon composite. What is the best way to adhere these fibres to nylon? Will epoxy work?

Would it be possible to melt the nylon and let the nylon solidify with fibres in it ?
Note, this will be done on a DIY basis.

Any other material ideas are more than welcome!

Thanks in advance

Nylon is a thermoplastic so yes.

Nylon composites are common, chances are you have some in your home or garage. Off the top of my head I have cheap garden tools and bicycle parts which are fibre reinforced nylon.
 
What about hempsilkotton?

Epoxy resins have polar OH-groups that make them adhere well to most fibres. You could use for an example glass fibre rowings or sheets as the reinforcement. You can use a mould or build your composite layer by layer on a flat surface and process it to desired shape by just cutting the edges. Glass fibre reinforced epoxy resin matrix composites are common in DIY projects.
