Sandwich Core Materials

Hi, I'm Steve from Fibre Glast. Today we're taking a look at the Sandwich Core materials available at FibreGlast. This category includes Nomex Honeycomb, EndGrain Balsa, and a selection of foam products. We use the term Sandwich Core because these materials are sandwiched between layers of reinforcement within your part. They are used to build bulk and strength for a part without adding significant weight. Parts made with sandwich core achieve a much higher flexural strength than using skin laminates alone. Sandwich core materials also build thickness into any composite part, which in turn, builds stiffness.

Let's take a closer look at each of our sandwich core categories, beginning with Nomex Honeycomb. Nomex Honeycomb is a sheet of cells, nested together to form panels with much the same look as a crosssection of beehive. It's extremely flexible, and when fully expanded, is almost entirely open space. It offers good impact resistance and is also fire retardant. Among sandwich core, Honeycomb offers the very best strengthforweight ratio. It is used primarily for structural applications in aerospace. EndGrain Balsa is the most widely used sandwich core material. It is constructed using small blocks of wood each bonded in succession to.

A light scrim fabric backing. As a result, it conforms to nearly any simple curve and most gradual compound curves. It offers a high compressive strength due to the density of the wood blocks. Balsa is often selected as a more affordable option compared to honeycomb or vinyl foams. Foams make up the last category of Sandwich Core. All foams at FibreGlast are rigid, closedcell foams, meaning they resist water, gas, and oil. They deliver added strength, stiffness, and insulation for parts, without adding significant weight. Foam is easy to handle, provides excellent flotation, and can.

Be easily carved or shaped. Our foam selections includes sheets of vinyl foam Divinymat flow media mixandpour polyurethane foams and sheets of polyisocyanurate foam. All the Sandwich Core materials at FibreGlast are compatible with epoxy, polyester, and vinyl ester resins, and can be used for most layup techniques, including vacuum bagging and infusion. Because of their combined strength, stiffness and bulk for low weight, they are popular for use with marine applications, like boat hulls, as well as aerospace and structural panels. To get more details on our entire selection of Sandwich Core materials, visit product pages at FibreGlast and watch spotlight tutorials.

EASY TO MAKE Paper Tower Challenge Tutorial

This is a small tutorial on how to build a paper tower and you'll need the items seen here so first you'll need to create three strips of paper and you should do that by drawing three strips on your piece of paper as i've already done with a ruler and a pencil and then cutting it out with scissors as shown here so now you an idea what the width of the paper should be like, and you'll be folding these as shown here into triangular prisms and to tape them together.

I'd recommend three two at the end as shown and one in middle just for extra stability do this with the other two and you're set now to create the base of the paper tower you'll need four strips of paper these can be roughly the same size it doesn't matter so much here cut them out then you'll be doing what you did in the previous step where you turned them into triangular prisms in this case i've taped the middle as well and you can see that it's quite sturdy.

Do this with the other three and you'll be ready to start creating the base of the tower so you'll be using three to create a triangular based pyramid and one to attach the three legs to as shown here and you should probably cut out another piece of paper and do what i did just join the legs together to make them stable and now for the body the three triangular prisms you've created earlier should slip inside each other as shown here and make sure they fit snugly so that your tower doesn't start to lean.

Fiberglass Boat Repair, Wooden Yacht Bow Deck, System 3 Silvertip Epoxy

So here's that same Chris Craft bow deck, and we've just put a coat of epoxy with fibreglass cloth on it. We're using this system three laminating resin, and the hardener there, and that's a very good epoxy. It allows the fresh, or the raw plywood to soak up a certain amount of that epoxy, and then wetting the cloth into it, makes the two bond together, form a bit of a watertight seal, or hopefully a watertight seal. And we'll put another coat of the resin on it, and the hardener mixed into it,.
