To build the blank, I used CFW epoxy because it does not chemically attack the foam. However, the hard glue lines at each layer of foam can cause difficulties when shaping the part.   Styrofoam has a density of about 2 pounds per cubic foot—very low. Unless the density of the glue line approximates the foam, the shaping process will remove foam much more quickly than the glue lines. This leaves unacceptable ridges at each joint in the foam. So to make shaping easier, I used epoxy thickened with 410 Microlight to glue the layers of Styrofoam together. Microlight has a very low density and does not make hard glue lines that other fillers might. Breather Fabric Tue, 19 Nov 2019 00:00:00 +0530 We've received a couple of requests for "bleeder" fabric, but that's a material we're not familiar with. Any ideas?A bleeder fabric is typically part of a composite material and is used in applications such as vacuum bagging.   A "breather" will evacuate air, while the "bleeders" absorb excess resins so that they don't go somewhere they might become a problem. Bleeder fabrics can be made from several different fiber types and are typically made of nonwoven constructions. In some instances, one fabric can act as both a breather and a bleeder.

Core Foam Tue, 19 Nov 2019 00:00:00 +0530 By using core between two composite, alloy or wood skins, you can create a lighter, stronger and stiffer part than with a solid laminate. However, different types of cores have a wide range of properties and unique characteristics. Proper structural engineering is necessary to optimize performance and minimize cost.Core Composites provides only general technical data as an accommodation to assist our customers.

Epoxy Gelcoat Tue, 19 Nov 2019 00:00:00 +0530 Epoxies are best known for their excellent adhesion, chemical and heat resistance, mechanical properties, and outstanding electrical insulating properties. The chemical resistance of epoxies is excellent against basic solutions (best choice for brine tanks).Epoxies are more expensive than polyesters, and cure times are longer, but their extended range of properties can make them the cost/performance choice for critical applications. Glass Fiber Tue, 19 Nov 2019 00:00:00 +0530 The versatility of glass as a fiber makes it unique industrial textile material. Glass fiber in fabric form offers an excellent combination of properties from high strength to fire resistance. Wide ranges of yarn sizes and weave patterns provide huge number of design potential allowing the end user to choose the best combination for material performance, economics and flexibility. Infusion Resin Trap Tue, 19 Nov 2019 00:00:00 +0530 Infusion represents a class of closed mold manufacturing processes whereby dry fabric — carbon, glass, aramid or natural is placed in a mold and infused with a liquid resin under heat and vacuum to distribute the resin throughout all fabric layers. Our anti-corrosive infusion resin traps are available in various lengths ranging up to 6m.  Kevlar Fabric Tue, 19 Nov 2019 00:00:00 +0530 In a world where lightweight and durable composites are increasingly replacing conventional materials, para-aramid fibers play an important role. They are essential for reinforcing composites where weight reduction and excellent damage tolerance are required. For over three decades, CFW Aramid has been committed to providing high-tech solutions for composite-based applications in marine and aerospace construction, civil engineering, ground transportation, engineering plastics, and sporting goods – and the number of applications is growing. PU Liquid Foam Tue, 19 Nov 2019 00:00:00 +0530 It is sprayed on as a liquid which reacts and expands in place. This expansion action also seals all of the cracks and crevasses in your wall's exterior sheathing. The result is that air can no longer slip in – your house will be less drafty and more comfortable. Air leakage can also introduce moisture into the wall cavity, resulting in wet insulation and mold and mildew. With the sealing effects of polyurethane foam insulation, this will not be a concern. Release Film Tue, 19 Nov 2019 00:00:00 +0530 Release Films are typically placed directly in contact with the laminate. They separate the laminate from breather/bleeder fabrics, which have no release characteristics, while the thin plastic release film has been treated so it won't bond to the laminate. There are many types of release films available and selection will depend on such things as the cure temperature, pressure, complexity of component and resin system involved. Release films can be perforated or non perforated depending on whether or not resin bleed is necessary. Perforations enable trapped air, volatiles or excess resin, which may compromise the physical properties of the laminate, to be removed. Various perforation patterns are available with P3 being a standard medium bleed perforation and P31 a high bleed infusion perforation. Vacuum Bagging Film Tue, 19 Nov 2019 00:00:00 +0530 High performance vacuum bagging film in a lay flat tube suitable for use in all composites vacuum bagging applications, including conventional vacuum bagging, resin infusion and pre-preg parts manufacture.The lay flat tube (LFT) configuration means that the film is essentially a giant tube of bagging film meaning that half of the seams for many applications are already there, reducing the amount of gum tape needed and reducing the likelihood of leaks. The film is 1.52m wide and with the two sides of the tube results in 3.04sqm per linear metre ordered.This high performance bagging film is tear resistant and suitable for use in operating temperatures up to 204°C. Vacuum Pump Tue, 19 Nov 2019 00:00:00 +0530 Vacuum bagging is a commonly used technique in composites, and for good reason. When done correctly, your part will have a nice, uniformly distributed compression about the surface of the layup. This in turn helps to minimize any voids (e.g. bubbles and wrinkles) in the buildup of layers. Also, when used with a porous substrate made of peel-ply and breather-cloth as we'll see, it assists in having the optimal ratio of resin to reinforcement (e.g fiberglass, or carbon fiber) by squeezing out the excess.The project is quite simple for illustrative purposes. I'm making a small container from a mold of a nice tea container lid. I'll go over the steps to make this part, but the vacuum bagging phase is what this topic is about, so we'll be delving into that a bit more thoroughly. Vinyl Ester Resin Tue, 19 Nov 2019 00:00:00 +0530 Vinyl esters are halfway between polyesters and epoxies as far as typical properties and toughness, and they are a step up on a cost basis. Their longer double bonded vinyl groups that link the ester groups together contribute a flexible nature to the resin. That flexible nature produces parts that withstand impacts and repeated flexing without developing cracks.Vinyl esters provide excellent resistance to water, organic solvents and alkalis, but less resistance to acids than polyesters. Vinyl esters are stronger than polyesters and more resilient than epoxies. Molding conditions for vinyl esters are similar to those for polyesters.
