Hello,

Of all the crashed cargo I visited, never have I obtained a salvaged frigate module, and only once in a mission with my frigates.
I might be unlucky, but in the event I am not the only one having this issue here is a mod that allows you to craft it yourself, along with the storage augmentation module, the cargo bulkhead, the repair kits, the multi-tool expansion slot and now the exosuit expansion unit.

You will have to break into a protected manufacturing facility for that, resolve the riddle and then, when you have the possibility to unlock new technology, under the tree where you probably already unlocked the circuit board, you will be able to unlock all of these modules !
EDIT : Changed the location, from "Valuable Products" to "Components & Devices" since adding more where it used to be was cropping the other items at the edges of the screen.

In order to use it you just have to put the "Craftable Modules.pak" file in the folder MODS in  *\Steam\steamapps\common\No Man's Sky\GAMEDATA\PCBANKS". Create the folder if there isn't one already. 
Also, delete or rename "DISABLEMODS.TXT" into "ENABLEMODS.TXT". You will find this file in PCBANKS.

You can also use the lua script provided.
