Resin infusion

SCRIMP process This Seeman Composites Resin Infusion Process (SCRIMP) is described as a gas-assist resin transfer molding process. As an example glass fiber fabrics/ thermoset vinyl ester polyester plastic and polyurethane foam panels (for insulation) are placed in a segmented tool. A vacuum is pulled with a bag so that a huge amount of plastic can be drawn into the mold (Marco process approach). Its curved roof is made separately and bonded to the box with mechanical and adhesive fastening. It is similar to various reinforced plastics molding processes. [Pg.522]

Epoxy vinyl ester resins are a special class of unsaturated resin. This resin is made by capping an epoxy resin with methacrylic acid and then dissolving in styrene monomer to the desired viscosity. This gives mechanical properties similar to epoxy resins, but the processibility (low viscosity allowing for resin infusion processes) of an unsaturated polyester resin. As with unsaturated vinyl esters, the most common fire retardant vinyl ester resin is based on a resin made from a halogenated system, tetrabromobisphenol A. The level of bromine in the resin and the presence of antimony will determine the fire performance of the resin. These resins are normally used for corrosion resistant equipment or when fire performance and high mechanical properties are required. It is very difficult to get a low smoke value with a brominated vinyl ester resin again due to the fact that bromine... [Pg.705]

The vacuum assisted liquid molding process has been used for the manufacture of large composite parts. In this process, a preform is placed in an open mold and a plastic vacuum bag placed on top of the mold. A vacuum is created in the mold using a vacuum pump. A resin source is connected to the mold. As vacuum is drawn through the mold, resin infuses into the preform. Application includes the fabrication of large products with complex geometry such as panels of allcomposite buses, railroad cars, and vehicle components. [Pg.509]

The VARTM is a hquid resin infusion process and is currentiy considered by the aircraft industry to be the favoured low cost manufacmring process for the future. It is an autoclave-free process that has been identified as reducing the cost of component processing. It is reported that dimensional tolerance and mass measurements are comparable with stitched RFI autoclave panels. A conventional blade stiffened test panel (3 X 2 ft with 4-in-high blades 0.5 in thick) has been manufactured recently at NASA by using the VARTM method, achieving a reasonable quahty. [Pg.11]

Uniaxial tensile tests have been performed for four-ply and one-ply composites based on glass plain-weave reinforcement — Table 2.3. The composites are produced by resin infusion moulding using Dow Derakane 8084 Epoxy-Vinyl Ester resin. The weave architecmre is slightiy unbalanced exhibiting different crimp in warp and weft directions. The lay-up of four-ply composite has been balanced. [Pg.43]

SCRIMP This process involves placing a peel-ply and distribution medium between the fibre preform and the vacuum bag (Figure 3.7). Advantages include speeding up the filling process, i.e. resin infusion. [Pg.69]

Two of the most popular of these processes are CRTM which is reviewed by Bickerton and Kelly (2012) [22] and VARTM which is discussed by Hsiao and Heider (2012) [23]. The use of vacuum to develop resin-infusion processes has been one of the most successful developments in reducing the problem of voidage as well as speeding up the process. Vacuum-based processes have enjoyed enormous growth in popularity... [Pg.70]

Other types of low viscosity resins suitable for processing by resin transfer molding and resin infusion are based on 4,4 -BPDA, 2,2 -bis(4-(4-amino-phenoxy)phenyl)propane and CA. 1 mole of 4,4 -BPDA is used the other compounds are fed in amounts of 2 mole. [Pg.487]

A lead adopter, at least among production boat builders, of new resin film infusion materials is the French company Poncin Yachts, which offers hulls laid up in SP Systems Resin Infusion Technology (SPRINT) material. The company could equally have chosen Hexcel Composites HexFit, or another of the several semi- preg products now available on the market. [Pg.322]

This Seeman Composites Resin Infusion Process (SCRIMP) has been used to manufacture corrosion resistance bus shells (Chapter 5). North America Bus Industries (NABI) of Anniston, AL uses glass fiber-polyester plastic material from TPI Composites of Warren, RI. These new buses weigh about 10,000 kg (22,000 lb) that is 3200 kg (7000 lb) lighter than steel units. Lighter weight results in reduced axial loads, brake wear, etc. and improved fuel efficiency. [Pg.528]

Figure 10.7 Example of a cricket helmet (RawTek ) from Ayrtek . The helmet is made from carhon fiber via placing the material into a female mold that is vacuum-bagged and placed in an autoclave to cure it as the resin infuses into the material, forming the shell. The helmet also features a grade 5 titanium grille that comes standard with this model. With kind permission from Ayrtek Limited. Figure 10.7 Example of a cricket helmet (RawTek ) from Ayrtek .
