I infused a boat Earlier this year. Strength for regular Kevlar canoe use should be fine. I have seen partial layers delaminate at the seams when rocks/rapids come knocking on the hull, though. Remember, Birchbark canoes of old were made of partials stitched and pitched together and they worked well enough to develop the entire fur trade industry. |

Can two infusions make overall weaker hull? One more question: I see people usually doing thwart and gunwale from carbon fiber. Why not kevlar? |

-you will use twice the infusion consumables (peelply/mesh/tubing/vac bag). -you will need to finish the outside of the canoe to a gloss by ‘filling the weave’ with epoxy and then sanding/polishing to a gloss. Given the complexity of infusion, you might want to reconsider if it is the right technique for your build. I can recommend the James Moran book on building a Kevlar boat over a male mold- I’ve seen some very functional boats built with that technique. |

Any thought about my other ideas? |

From your experience, how much may it affect hull strength? Is it worth it to consider making it from pieces or better not to take a risk and go with one piece per layer? Thank you for your time. Andrei |

Thanks a lot! |

From your thread on canoe you used 5lb foam for core. I have access to 4lb and 6lb. Will 4lb work or better to go with 6lb? |

ak44: " Kevlar only surface bonds with the resin (the main reason that a kevlar hull is lighter than fiberglass is due to the reduced need for resin rather than the weight of the cloth), the fibers don't "wet through"- any abrasion that goes through the resin results in the exposure of frayed fiber. |

With fiberglass as outer layer, next 2 layers of 5oz kevlar, next foam core and kevlar over core. It will be my first serious project, so I'm not really run for perfection, just to have decent view. How it all sounds for you, if I do it from pieces, doable? |
