    Australian Names for USA Fibreglass Products

    Hello All,

    I have been watching a number of YouTube clips about carrying out fibreglass repairs - especially for fixing holes. "Bluey" my ex-Telecom Linesman's Van has a fibreglass back which has seen better days and now needs a fair bit of work done. Oh, and a previous owner put in a roof rack that has set of supports that go from the cargo area via a series of holes cut through the roof.

    One of the YouTube sites I have been watching mentions using 1.5 Ounce Chop Strand Matting and 1708 biaxial fibreglass. Are the products available in Australia? If so what are they know as through fibreglass suppliers in Queensland? I found a USA-based source The Fiberglass Site which provides an image that shows close-up detail on the 1708 - accessed from http://fiberglasssite.com/biaxial-mat-1708-5-yards-x-50


    The clips are were accessed via BoatWorks Today on the 13th October 2020 from, Fiberglass Boat Repair~ There's A Hole In My Boat Part 1 - YouTube

    Kind regards

    Try Fibreglass cloth, Fibreglass resin - Fibreglass Sydney at Seven Hills in Sydney

    I think this is the same mob from which I used to buy CSM (chopped strand mat), cloth, and resin years ago (then called Fibreglass Material Services - also in Seven Hill but a different street).

    They have double bias, triaxial, quadaxial, etc., materials Product List - Fibreglass Sydney

    If you have a whitworths boat shop near you, or other such like marine shops, they carry a range of fibreglass mat, cloth, resin etc. I used to use polyester resin, but recently used Epoxy resin when doing quite major repairs to a fibreglass tractor roof, good stuff.

    Those clothes you mention, would be chopped strand matting, and 'cloth' or dynel I think they also call it.

    the cloth is also known as woven rovings and can be purchased in various degrees of coarseness.

    it nearly always leaves lines on overlays , no matter how hard you stipple and ends up being much heavier than chopped strand mat , which is just easier to work but not as strong.

    Hi Lionel,
    I have been using AA Composites / AA fibgreglass in Hemant Bris, http://aafibreglass.com.au/ .
    I'm a bit of a novice but they have been patient enough with my endless questions over the years. I've done a bit of repairing to boats and Kayaks.
    Hope I'm not telling you how to suck eggs, but US based weights are Ounce per square foot where as we use grams per square meter.

    Chopped strand matting is chopped strand bound together with a binder, random directions, where as cloth can be chopped strand but held together with a weave (or stitching) or more usually a woven cloth like the material in your shirt.
    AFAIK, Biaxial or double bias is usually a cloth of two layers one layer has all the main threads running one way and the second layer all of the main threads running at 90 degrees. It's all held together with light stitching or a weave. The photo you have shown is not the type of stuff I am used to as biaxial.
    Double bias will let you get around compound curves a lot more easily than woven cloth as the two layers can slide over each other a bit so you don't get wrinkles as easily.

    Epoxy is great, pretty much sticks to everything a lot more easily than polyester resin, and you can get more open time with it if you use the right hardener, so if your by yourself and the jobs fiddley then it's the way to go. However the vast majority of chopped strand matting will have a binder that is incompatible with epoxy, so decide on the resin before ordering and make sure your getting compatible products ie no resin if using epoxy. Also polyester will not stick to epoxy, so it's a one way street.

    There are a range of low volatile epoxy's on the market now which get around the problem of amine allergy's from exposure to the uncured hardener but they are a bit more expensive, which ever way you go, keep protected, I've been living with my allergy for about 25 years it's not fun and it never goes away.

    The great thing about fibre glassing is that any mistakes can be sanded away.

    Been using this stuff professionally since I was 14, so it's nearly 50 years. (at the highest level............ surfboards and then later, custom windsurfers)

    Polyester resin and most likely 300gm chopped strand is all you need.......... easier to work with and would match the original thing that needs repairing.

    If you take pics of each 'wound' I should be able to help you fix it and others can learn.

    PM if you want.

    ATM I'm doing a really stupid big job and could post you enough 300gm and 4oz woven leftovers for jack.

    cheers, DL

    Try doing that when the resin is still sticky a week later from someone else's lack of expertise.

    What would you do then?

    I would be cursing my lack of experience.
