    Has anyone worked with UHMWPE Cloth (or hybrid with carbon/Kevlar) as a substitute for Kevlar or otherwise, in a composite laminate?
    Interested in potential applications for this.
    Apparently there are issues with resin adhering to the UHMWPE fiber but looks like there are a number of military applications where they have got this right for armor ...

    Beware that the temperature capabilities are low for Spectra, etc.
    Might not matter.

    Spectra has really poor bond to resins. In armor use that can be an advantage as fibers are able to slide inside the matrix dividing impact energy to larger area. In other uses that kind of action is not a sign of good laminate.

    UHMWPE cloths are corona treated when used in laminates. They have been used by some sailplane manufacturers for pilot protection in forward fuselages. Resin matrix is epoxy.

    I don't know of many (if any) resins that truly bond to polyethylene or polypropylene. ??

    Heat fusing to other materials has seen some success, but that is basically a mechanical bond.
