clamp various fluid systems/modules to the cryogenic fluid

connected structures. Since the tanks and flow lines are carr

glass fabric & LY 5052 resin composite system. This material

The Elements (Brackets, Isolators, etc.) are to be realized o

conforming to the dimensions and other requirements given in t

the particular type of Element.

The composite system is realized by appropriately laying-up

mould (matched-die type for obtaining the required compaction

by following the recommended curing cycle as mentioned

feed stock of the material - in the shape and size shown in the

given at the edges for trimming – wherein, from the feed stock

Getting a higher number of individual components from a sin

moulded using a larger mould realized after economically schem

suitable parting/trepanning operations using a precise machine

Use (0°, 45°) combination lay-up sequence for all the products.

Symmetric lay-up sequence is to be maintained for all sectio

layers and lay-up sequence for different laminate thickness are

Wherever variable thickness is coming, filler layers to be used

Wherever possible, one bigger size feedstock to be processe
