Reaction of maleic anhydride grafted polypropylene with carbon fibre

Hey
I am a PhD student in Mechanical Engineering and have recently done some XPS work to characterise the functional groups on the surface of carbon fibre to help explain changes in adhesion between different fibre treatments.
I am willing to admit my chemistry knowledge is not great, although I have been trying to work at it!

My question is whether groups such as carbonyl, carboxylic acid and hydroxyl carbon (which are present on the surface of the fibres) are able to form chemical bonds with maleic anhydride, and what functional groups in the maleic anhydride can they react with?

From reviewing literature on the topic, most authors don't go into any detail about what chemical bonding is taking place, I have found that carboxylic acid groups are known for bonding with carbonates, sulfones and imides in other thermoplastics, but like I said I am struggling a bit with the chemistry

If anyone can even point me in the right direction with where I would be able to find this info (books, journals etc.) I would be extremely grateful!

Thanks

Technically, mechanical engineering is the application of the principles and problem-solving techniques of engineering from design to manufacturing to the marketplace for any object. Mechanical engineers analyze their work using the principles of motion, energy, and force—ensuring that designs function safely, efficiently, and reliably, all at a competitive cost.

Mechanical engineers make a difference. That's because mechanical engineering careers center on creating technologies to meet human needs. Virtually every product or service in modern life has probably been touched in some way by a mechanical engineer to help humankind.

This includes solving today's problems and creating future solutions in health care, energy, transportation, world hunger, space exploration, climate change, and more.

Being ingrained in many challenges and innovations across many fields means a mechanical engineering education is versatile. To meet this broad demand, mechanical engineers may design a component, a machine, a system, or a process. This ranges from the macro to the micro, from the largest systems like cars and satellites to the smallest components like sensors and switches. Anything that needs to be manufactured—indeed, anything with moving parts—needs the expertise of a mechanical engineer.
