CNG Composite Cylinders (Type IV) VII. Hole 38 locates the sleeve ports relative to the intermediate mold so the fins are formed in the correct places.The removable core is continuous and integral and keys itself to the sleeve.

However, all process variations have the common features of holding unresinated fibres within a closed tool cavity with a differential pressure applied to a supply of resin such that the resin permeates into the reinforcement. and lower maintenance requirements, they are much more customer-friendly.

reducing the core and removing the material, whereby to form a cylinder head assembly with a clear bore, open ports, and at least one passage communicating with a port and extending axially alongside the outer wall of the sleeve.Process for making a composite cylinder head assembly The completed cylinders are pressure-tested with air. The composite materials will remain rust-free and low-maintenance—soap and water is all that is needed to clean the outside of the cylinder. I have actually written about a specific application of AFP here When I wrote this post I wasn’t aware of Boeing’s capability in detail. The primary market to be targeted first is the grill cylinder business-marketing to retailers and directly to customers.

Proposals to change NFPA’s code governing the use of propane and cabinet heaters is also in the negotiation stages. A number of propane cylinder manufacturers began exploring the possibility of using the material in the 1980s. This will allow the gas to seep through the walls slowly instead of releasing large amounts of gas through the valve. This leaves the liner in contiguous contact with the surrounding cast cylinder head construction.

composite components. Cylinders made of composite material are one of the most significant developments in the last 60 years. After hardening, the two halves are de-moulded and then joined using a specially-developed method.
Filament winding creates too much build up of material on changing geometries where weight sensitivity is an issue. A kind of composite L PG gas cylinder moulding process, first blowing adopts the inner bag of bottleneck and body integration blow molding method, the unnecessary material of inner bag is carried out process and forms ganoid inner bag, to bottleneck mounting flange, valve seat, the parts such as sealing ring, use wrapping machine that inner bag carries out the high-speed coiling of fortifying fibre layer, valve is installed, Wrapping formed gas cylinder is put into the station of injecting glue, gel-injection mould is combined and seals, the pressurization being carried out glue by adhesive pouring nozzle is injected, glue is enable to infiltrate through fibrolaminar each filament surface, at the intrinsic pressure hydraulic pressure being consistently higher than gum-injecting port being maintained with inner bag of injecting glue thus preventing inner bag and fibrolaminar deformation;Realize the curing molding to glue by heating and cooling down mould, finally add handle, foot ring and protective jacket. CN1196462A discloses compressed natural gas used as vehicle fuel composites gas cylinder and manufacture method thereof; first; plastic inner container adopts rolling technique, and its shaping efficiency relatively blow molding process is poor and needs perforate operation, secondly; its winding process adopts Wet Winding Process; relatively dry fibers is wound around speed difference, glue waste and processing environment can be caused unclean, finally; the gas cylinder of its production needs to cover external protection processed, affects whole production efficiency and cannot observe level change in bottle. The term does not include formation in multiple sections which are separately removed.This invention is not to be limited by the embodiments shown in the drawings and described in the description, which are given by way of example and not of limitation, but only in accordance with the scope of the appended claims.A cast composite cylinder head assembly for an internal combustion engine having a cylinder liner cast integrally with a cylinder head, and a process for making the same wherein, as the consequence of a casting process, open continuous passages can be formed inside the cylinder head itself, in a bore in the liner, and in ports through the liner.1.
