Yes they are. Membranophones and Idiophones are categories in the percussion family.
It can be Idiophones and Membranophones or Pitched and Unpitched percussion.
They are Percussion Instruments. Specifically Membranophones
Membranophones Chordophones Idiophones Percussion
All can be considered as a percussion instrument but the Chordophone is not really a "Main" category in percussion. The two major category in percussion are Membranophones and Idiophones but there are chordophones that can be considered as a percussion instrument. An example of this is the piano. It produces sounds by its strings so its a chordophone but the strings are hit by little hammer so that they would vibrate and produce sound.
Drums are members of the percussion family of instruments.
There are two main classifications of percussion instruments. Idiophones include things such as cymbols and maracas. Membranophones include common instruments such as drums.
Percussion instruments can be categorized into two main groups: pitched percussion and unpitched percussion. Pitched percussion instruments produce definite pitches, such as xylophones and marimbas, while unpitched percussion instruments produce indefinite pitches, such as drums and cymbals.
Not quite sure what you are asking here, but....Percussion can be broken down into two families of instruments, the membranophones and the idiophones. the membranophones are the skinned drums. the idiophones are the rest of the percussion family, they use their bodies to make a sound, so are self-sounding (the meaning of idiophone).Beyond these calsses, we can talk about the types of materials used to make idiophonesmetalglasswoodbonestoneplasticvegetable - dried gourds (pumpkin and squash family) are used in a lot of instruments
For Membranophones, It is a stretched membrane such as an animal skin that vibrates which produces sounds. Examples of membranophones are Drums,Timpani,etc. For Idiophones it is the vibration of the whole instrument as a whole which produces sound. Examples of idiophones are Shakers,Cowbells, Cymbals,etc.

Mostly out of skin but the membranophones of the drum set are made out of plastic.
No. Membranophones are drums, with a skin or drum head tightened over a frame.
